+The following flags can be OR'ed together to allow a client to make changes to the default stream behavior:<p>
+<ul>
+<li><em>RTAUDIO_NONINTERLEAVED:</em> Use non-interleaved buffers (default = interleaved).</li><li><em>RTAUDIO_MINIMIZE_LATENCY:</em> Attempt to set stream parameters for lowest possible latency.</li><li><em>RTAUDIO_HOG_DEVICE:</em> Attempt grab device for exclusive use.</li></ul>
+<p>
+By default, <a class="el" href="classRtAudio.html">RtAudio</a> streams pass and receive audio data from the client in an interleaved format. By passing the RTAUDIO_NONINTERLEAVED flag to the openStream() function, audio data will instead be presented in non-interleaved buffers. In this case, each buffer argument in the RtAudioCallback function will point to a single array of data, with <code>nFrames</code> samples for each channel concatenated back-to-back. For example, the first sample of data for the second channel would be located at index <code>nFrames</code> (assuming the <code>buffer</code> pointer was recast to the correct data type for the stream).<p>
+Certain audio APIs offer a number of parameters that influence the I/O latency of a stream. By default, <a class="el" href="classRtAudio.html">RtAudio</a> will attempt to set these parameters internally for robust (glitch-free) performance (though some APIs, like Windows Direct Sound, make this difficult). By passing the RTAUDIO_MINIMIZE_LATENCY flag to the openStream() function, internal stream settings will be influenced in an attempt to minimize stream latency, though possibly at the expense of stream performance.<p>
+If the RTAUDIO_HOG_DEVICE flag is set, <a class="el" href="classRtAudio.html">RtAudio</a> will attempt to open the input and/or output stream device(s) for exclusive use. Note that this is not possible with all supported audio APIs. </td>

+The <a class="el" href="classRtAudio.html">RtAudio</a> API incorporates many of the concepts developed in the <a href="http://www.portaudio.com/">PortAudio</a> project by Phil Burk and Ross Bencina. Early development also incorporated ideas from Bill Schottstaedt's <a href="http://www-ccrma.stanford.edu/software/snd/sndlib/">sndlib</a>. The CCRMA <a href="http://www-ccrma.stanford.edu/groups/soundwire/">SoundWire group</a> provided valuable feedback during the API proposal stages.<p>
+The early 2.0 version of <a class="el" href="classRtAudio.html">RtAudio</a> was slowly developed over the course of many months while in residence at the <a href="http://www.iua.upf.es/">Institut Universitari de L'Audiovisual (IUA)</a> in Barcelona, Spain and the <a href="http://www.acoustics.hut.fi/">Laboratory of Acoustics and Audio Signal Processing</a> at the Helsinki University of Technology, Finland. Much subsequent development happened while working at the <a href="http://www-ccrma.stanford.edu/">Center for Computer Research in Music and Acoustics (CCRMA)</a> at <a href="http://www.stanford.edu/">Stanford University</a>. All recent versions of <a class="el" href="classRtAudio.html">RtAudio</a> have been completed while working as an assistant professor of <a href="http://www.music.mcgill.ca/musictech/">Music Technology</a> at <a href="http://www.mcgill.ca/">McGill University</a>.

+<h1><a class="anchor" name="apinotes">API Notes</a></h1><a class="el" href="classRtAudio.html">RtAudio</a> is designed to provide a common API across the various supported operating systems and audio libraries. Despite that, some issues should be mentioned with regard to each.<h2><a class="anchor" name="linux">
+Linux:</a></h2>
+<a class="el" href="classRtAudio.html">RtAudio</a> for Linux was developed under Redhat distributions 7.0 - Fedora. Three different audio APIs are supported on Linux platforms: <a href="http://www.opensound.com/oss.html">OSS</a> (versions >= 4.0), <a href="http://www.alsa-project.org/">ALSA</a>, and <a href="http://jackit.sourceforge.net/">Jack</a>. Note that <a class="el" href="classRtAudio.html">RtAudio</a> now only supports the newer version 4.0 OSS API. The ALSA API is now part of the Linux kernel and offers significantly better functionality than the OSS API. <a class="el" href="classRtAudio.html">RtAudio</a> provides support for the 1.0 and higher versions of ALSA. Jack is a low-latency audio server written primarily for the GNU/Linux operating system. It can connect a number of different applications to an audio device, as well as allow them to share audio between themselves. Input/output latency on the order of 15 milliseconds can typically be achieved using any of the Linux APIs by fine-tuning the <a class="el" href="classRtAudio.html">RtAudio</a> buffer parameters (without kernel modifications). Latencies on the order of 5 milliseconds or less can be achieved using a low-latency kernel patch and increasing FIFO scheduling priority. The pthread library, which is used for callback functionality, is a standard component of all Linux distributions.<p>
+The ALSA library includes OSS emulation support. That means that you can run programs compiled for the OSS API even when using the ALSA drivers and library. It should be noted however that OSS emulation under ALSA is not perfect. Specifically, channel number queries seem to consistently produce invalid results. While OSS emulation is successful for the majority of <a class="el" href="classRtAudio.html">RtAudio</a> tests, it is recommended that the native ALSA implementation of <a class="el" href="classRtAudio.html">RtAudio</a> be used on systems which have ALSA drivers installed.<p>
+The ALSA implementation of <a class="el" href="classRtAudio.html">RtAudio</a> makes no use of the ALSA "plug" interface. All necessary data format conversions, channel compensation, de-interleaving, and byte-swapping is handled by internal <a class="el" href="classRtAudio.html">RtAudio</a> routines.<p>
+At the moment, only one <a class="el" href="classRtAudio.html">RtAudio</a> instance can be connected to the Jack server.<h2><a class="anchor" name="macosx">
+Macintosh OS-X (CoreAudio and Jack):</a></h2>
+The Apple CoreAudio API is designed to use a separate callback procedure for each of its audio devices. A single <a class="el" href="classRtAudio.html">RtAudio</a> duplex stream using two different devices is supported, though it cannot be guaranteed to always behave correctly because we cannot synchronize these two callbacks. The <em>numberOfBuffers</em> parameter to the <a class="el" href="classRtAudio.html#a7">RtAudio::openStream()</a> function has no affect in this implementation.<p>
+It is not possible to have multiple instances of <a class="el" href="classRtAudio.html">RtAudio</a> accessing the same CoreAudio device.<p>
+The <a class="el" href="classRtAudio.html">RtAudio</a> Jack support can be compiled on Macintosh OS-X systems, as well as in Linux.<h2><a class="anchor" name="windowsds">
+Windows (DirectSound):</a></h2>
+In order to compile <a class="el" href="classRtAudio.html">RtAudio</a> under Windows for the DirectSound API, you must have the header and source files for DirectSound version 5.0 or higher. As far as I know, there is no DirectSoundCapture support for Windows NT. Audio output latency with DirectSound can be reasonably good, especially since <a class="el" href="classRtAudio.html">RtAudio</a> version 3.0.2. Input audio latency still tends to be bad but better since version 3.0.2. <a class="el" href="classRtAudio.html">RtAudio</a> was originally developed with Visual C++ version 6.0 but has been tested with .NET.<p>
+The DirectSound version of <a class="el" href="classRtAudio.html">RtAudio</a> can be compiled with or without the UNICODE preprocessor definition.<h2><a class="anchor" name="windowsasio">
+Windows (ASIO):</a></h2>
+The Steinberg ASIO audio API allows only a single device driver to be loaded and accessed at a time. ASIO device drivers must be supplied by audio hardware manufacturers, though ASIO emulation is possible on top of systems with DirectSound drivers. The <em>numberOfBuffers</em> parameter to the <a class="el" href="classRtAudio.html#a7">RtAudio::openStream()</a> function has no affect in this implementation.<p>
+A number of ASIO source and header files are required for use with <a class="el" href="classRtAudio.html">RtAudio</a>. Specifically, an <a class="el" href="classRtAudio.html">RtAudio</a> project must include the following files: <code>asio.h,cpp; asiodrivers.h,cpp; asiolist.h,cpp; asiodrvr.h; asiosys.h; ginclude.h; iasiodrv.h; iasiothiscallresolver.h,cpp</code>. The Visual C++ projects found in <code>/tests/Windows/</code> compile both ASIO and DirectSound support.<p>
+The Steinberg provided <code>asiolist</code> class does not compile when the preprocessor definition UNICODE is defined. Note that this could be an issue when using <a class="el" href="classRtAudio.html">RtAudio</a> with Qt, though Qt programs appear to compile without the UNICODE definition (try <code>DEFINES -= UNICODE</code> in your .pro file). <a class="el" href="classRtAudio.html">RtAudio</a> with ASIO support has been tested using the MinGW compiler under Windows XP, as well as in the Visual Studio environment. <HR>

For some stupid devices, like the Griffin iMic, the default format is 8-bit mono when the requested format and number of channels does not exist. So, we need to query the device's capabilities using the kAudioStreamPropertyPhysicalFormats selector - i.e. ask a device for all of the channels/format/rate combination that it supports - and then enumerate through them to pick the best one.</td></tr>

<p>
-A public method which sets a user-defined callback function for a given stream.
+A function that returns the index of the default output device.
<p>
-This method assigns a callback function to a previously opened stream for non-blocking stream functionality. A separate process is initiated, though the user function is called only when the stream is "running" (between calls to the <a class="el" href="classRtAudio.html#a13">startStream()</a> and <a class="el" href="classRtAudio.html#a14">stopStream()</a> methods, respectively). The callback process remains active for the duration of the stream and is automatically shutdown when the stream is closed (via the <a class="el" href="classRtAudio.html#a12">closeStream()</a> method or by object destruction). The callback process can also be shutdown and the user function de-referenced through an explicit call to the <a class="el" href="classRtAudio.html#a7">cancelStreamCallback()</a> method. Note that the stream can use only blocking or callback functionality at a particular time, though it is possible to alternate modes on the same stream through the use of the <a class="el" href="classRtAudio.html#a6">setStreamCallback()</a> and <a class="el" href="classRtAudio.html#a7">cancelStreamCallback()</a> methods (the blocking <a class="el" href="classRtAudio.html#a11">tickStream()</a> method can be used before a callback is set and/or after a callback is cancelled). An <a class="el" href="classRtError.html">RtError</a> will be thrown if called when no stream is open or a thread errors occurs. </td>
+If the underlying audio API does not provide a "default device", or if no devices are available, the return value will be 0. Note that this is a valid device identifier and it is the client's responsibility to verify that a device is available before attempting to open a stream. </td>

For example, if a system error occurs when processing the <a class="el" href="classRtAudio.html#a3">RtAudio::getDeviceCount()</a> function, the return value is zero. In such a case, the user cannot expect to make use of most other <a class="el" href="classRtAudio.html">RtAudio</a> functions because no devices are available (and thus a stream cannot be opened). A client can call the function <a class="el" href="classRtAudio.html#a16">RtAudio::showWarnings()</a> with a boolean argument to enable or disable the printing of warning messages to <code>stderr</code>. By default, warning messages are displayed. There is a protected <a class="el" href="classRtAudio.html">RtAudio</a> method, error(), that can be modified to globally control how these messages are handled and reported. <HR>

-<a class="el" href="classRtAudio.html">RtAudio</a> is a set of C++ classes which provide a common API (Application Programming Interface) for realtime audio input/output across Linux (native ALSA, JACK, and OSS), Macintosh OS X, SGI, and Windows (DirectSound and ASIO) operating systems. <a class="el" href="classRtAudio.html">RtAudio</a> significantly simplifies the process of interacting with computer audio hardware.

<p>
-<a class="el" href="classRtAudio.html">RtAudio</a> incorporates the concept of audio streams, which represent audio output (playback) and/or input (recording). Available audio devices and their capabilities can be enumerated and then specified when opening a stream. Where applicable, multiple API support can be compiled and a particular API specified when creating an <a class="el" href="classRtAudio.html">RtAudio</a> instance. See the <a class="el" href="index.html#apinotes">API Notes</a> section for information specific to each of the supported audio APIs.<p>
-The <a class="el" href="classRtAudio.html">RtAudio</a> API provides both blocking (synchronous) and callback (asynchronous) functionality. Callbacks are typically used in conjunction with graphical user interfaces (GUI). Blocking functionality is often necessary for explicit control of multiple input/output stream synchronization or when audio must be synchronized with other system events.<h2><a class="anchor" name="changes">
-What's New (Version 3.0)</a></h2>
-<a class="el" href="classRtAudio.html">RtAudio</a> now allows simultaneous multi-api support. For example, you can compile <a class="el" href="classRtAudio.html">RtAudio</a> to provide both DirectSound and ASIO support on Windows platforms or ALSA, JACK, and OSS support on Linux platforms. This was accomplished by creating an abstract base class, RtApi, with subclasses for each supported API (RtApiAlsa, RtApiJack, RtApiOss, RtApiDs, RtApiAsio, RtApiCore, and RtApiAl). The class <a class="el" href="classRtAudio.html">RtAudio</a> is now a "controller" which creates an instance of an RtApi subclass based on the user's API choice via an optional <a class="el" href="classRtAudio.html#w8">RtAudio::RtAudioApi</a> instantiation argument. If no API is specified, <a class="el" href="classRtAudio.html">RtAudio</a> attempts to make a "logical" API selection.<p>
-Support for the JACK low-latency audio server has been added with this version of <a class="el" href="classRtAudio.html">RtAudio</a>. It is necessary to have the JACK server running before creating an instance of <a class="el" href="classRtAudio.html">RtAudio</a>.<p>
-Several API changes have been made in version 3.0 of <a class="el" href="classRtAudio.html">RtAudio</a> in an effort to provide more consistent behavior across all supported audio APIs. The most significant of these changes is that multiple stream support from a single <a class="el" href="classRtAudio.html">RtAudio</a> instance has been discontinued. As a result, stream identifier input arguments are no longer required. Also, the RtAudio::streamWillBlock() function was poorly supported by most APIs and has been deprecated (though the function still exists in those subclasses of RtApi that do allow it to be implemented).<p>
-The <a class="el" href="classRtAudio.html#a9">RtAudio::getDeviceInfo()</a> function was modified to return a globally defined <a class="el" href="structRtAudioDeviceInfo.html">RtAudioDeviceInfo</a> structure. This structure is a simplified version of the previous RTAUDIO_DEVICE structure. In addition, the RTAUDIO_FORMAT structure was renamed RtAudioFormat and defined globally within <a class="el" href="RtAudio_8h-source.html">RtAudio.h</a>. These changes were made for clarity and to better conform with standard C++ programming practices.<p>
-The <a class="el" href="classRtError.html">RtError</a> class declaration and definition have been extracted to a separate file (<a class="el" href="RtError_8h-source.html">RtError.h</a>). This was done in preparation for a new release of the RtMidi class (planned for Summer 2004).<h2><a class="anchor" name="download">

-Latest Release (18 November 2005): <a href="http://music.mcgill.ca/~gary/rtaudio/release/rtaudio-3.0.3.tar.gz">Version 3.0.3</a><h2><a class="anchor" name="start">
-Getting Started</a></h2>
-With version 3.0, it is now possible to compile multiple API support on a given platform and to specify an API choice during class instantiation. In the examples that follow, no API will be specified (in which case, <a class="el" href="classRtAudio.html">RtAudio</a> attempts to select the most "logical" available API).<p>
-The first thing that must be done when using <a class="el" href="classRtAudio.html">RtAudio</a> is to create an instance of the class. The default constructor scans the underlying audio system to verify that at least one device is available. <a class="el" href="classRtAudio.html">RtAudio</a> often uses C++ exceptions to report errors, necessitating try/catch blocks around most member functions. The following code example demonstrates default object construction and destruction:<p>
-<div class="fragment"><pre class="fragment"><span class="preprocessor">#include "RtAudio.h"</span>
-
-<span class="keywordtype">int</span> main()
-{
- <a class="code" href="classRtAudio.html">RtAudio</a> *audio = 0;
-
- <span class="comment">// Default RtAudio constructor</span>
- <span class="keywordflow">try</span> {
- audio = <span class="keyword">new</span> <a class="code" href="classRtAudio.html">RtAudio</a>();
- }
- <span class="keywordflow">catch</span> (<a class="code" href="classRtError.html">RtError</a> &error) {
- <span class="comment">// Handle the exception here</span>
- error.<a class="code" href="classRtError.html#a2">printMessage</a>();
- }
-
- <span class="comment">// Clean up</span>
- <span class="keyword">delete</span> audio;
-}
-</pre></div><p>
-Obviously, this example doesn't demonstrate any of the real functionality of <a class="el" href="classRtAudio.html">RtAudio</a>. However, all uses of <a class="el" href="classRtAudio.html">RtAudio</a> must begin with a constructor (either default or overloaded varieties) and must end with class destruction. Further, it is necessary that all class methods that can throw a C++ exception be called within a try/catch block.<h2><a class="anchor" name="error">
-Error Handling</a></h2>
-<a class="el" href="classRtAudio.html">RtAudio</a> uses a C++ exception handler called <a class="el" href="classRtError.html">RtError</a>, which is declared and defined in <a class="el" href="RtError_8h-source.html">RtError.h</a>. The <a class="el" href="classRtError.html">RtError</a> class is quite simple but it does allow errors to be "caught" by <a class="el" href="classRtError.html#w11">RtError::Type</a>. Almost all <a class="el" href="classRtAudio.html">RtAudio</a> methods can "throw" an <a class="el" href="classRtError.html">RtError</a>, most typically if a driver error occurs or a stream function is called when no stream is open. There are a number of cases within <a class="el" href="classRtAudio.html">RtAudio</a> where warning messages may be displayed but an exception is not thrown. There is a protected <a class="el" href="classRtAudio.html">RtAudio</a> method, error(), that can be modified to globally control how these messages are handled and reported. By default, error messages are not automatically displayed in <a class="el" href="classRtAudio.html">RtAudio</a> unless the preprocessor definition __RTAUDIO_DEBUG__ is defined. Messages associated with caught exceptions can be displayed with, for example, the <a class="el" href="classRtError.html#a2">RtError::printMessage()</a> function.<h2><a class="anchor" name="probing">

-The <em>nativeFormats</em> member of the <a class="el" href="structRtAudioDeviceInfo.html">RtAudioDeviceInfo</a> structure is a bit mask of the above formats that are natively supported by the device. However, <a class="el" href="classRtAudio.html">RtAudio</a> will automatically provide format conversion if a particular format is not natively supported. When the <em>probed</em> member of the <a class="el" href="structRtAudioDeviceInfo.html">RtAudioDeviceInfo</a> structure is false, the remaining structure members are undefined and the device is probably unuseable.<p>
-While some audio devices may require a minimum channel value greater than one, <a class="el" href="classRtAudio.html">RtAudio</a> will provide automatic channel number compensation when the number of channels set by the user is less than that required by the device. Channel compensation is <em>NOT</em> possible when the number of channels set by the user is greater than that supported by the device.<p>
-It should be noted that the capabilities reported by a device driver or underlying audio API are not always accurate and/or may be dependent on a combination of device settings.

-The <a class="el" href="classRtAudio.html#a4">RtAudio::openStream()</a> method attempts to open a stream with a specified set of parameter values. In this case, we attempt to open a two channel playback stream with the default output device, 32-bit floating point data, a sample rate of 44100 Hz, a frame rate of 256 sample frames per read/write, and 4 internal device buffers. When device = 0, <a class="el" href="classRtAudio.html">RtAudio</a> first attempts to open the default audio device with the given parameters. If that attempt fails, <a class="el" href="classRtAudio.html">RtAudio</a> searches through the remaining available devices in an effort to find a device that will meet the given parameters. If all attempts are unsuccessful, an <a class="el" href="classRtError.html">RtError</a> is thrown. When a non-zero device value is specified, an attempt is made to open that device <em>ONLY</em> (device = 1 specifies the first identified device, as reported by <a class="el" href="classRtAudio.html#a9">RtAudio::getDeviceInfo()</a>).<p>
-<a class="el" href="classRtAudio.html">RtAudio</a> provides four signed integer and two floating point data formats that can be specified using the RtAudioFormat parameter values mentioned earlier. If the opened device does not natively support the given format, <a class="el" href="classRtAudio.html">RtAudio</a> will automatically perform the necessary data format conversion.<p>
-The <em>bufferSize</em> parameter specifies the desired number of sample frames that will be written to and/or read from a device per write/read operation. The <em>nBuffers</em> parameter is used in setting the underlying device buffer parameters. Both the <em>bufferSize</em> and <em>nBuffers</em> parameters can be used to control stream latency though there is no guarantee that the passed values will be those used by a device (the <em>nBuffers</em> parameter is ignored when using the OS X CoreAudio, Linux Jack, and the Windows ASIO APIs). In general, lower values for both parameters will produce less latency but perhaps less robust performance. Both parameters can be specified with values of zero, in which case the smallest allowable values will be used. The <em>bufferSize</em> parameter is passed as a pointer and the actual value used by the stream is set during the device setup procedure. <em>bufferSize</em> values should be a power of two. Optimal and allowable buffer values tend to vary between systems and devices. Check the <a class="el" href="index.html#apinotes">API Notes</a> section for general guidelines.<p>
-As noted earlier, the device capabilities reported by a driver or underlying audio API are not always accurate and/or may be dependent on a combination of device settings. Because of this, <a class="el" href="classRtAudio.html">RtAudio</a> does not attempt to query a device's capabilities or use previously reported values when opening a device. Instead, <a class="el" href="classRtAudio.html">RtAudio</a> simply attempts to set the given parameters on a specified device and then checks whether the setup is successful or not.<h2><a class="anchor" name="playbackb">

-Once the device is open for playback, there are only a few final steps necessary for realtime audio output. We'll first provide an example (blocking functionality) and then discuss the details.<p>

-The first thing to notice in this example is that we attempt to open a stream during class instantiation with an overloaded constructor. This constructor simply combines the functionality of the default constructor, used earlier, and the <a class="el" href="classRtAudio.html#a4">RtAudio::openStream()</a> method. Again, we have specified a device value of 0, indicating that the default or first available device meeting the given parameters should be used. An attempt is made to open the stream with the specified <em>bufferSize</em> value. However, it is possible that the device will not accept this value, in which case the closest allowable size is used and returned via the pointer value. The constructor can fail if no available devices are found, or a memory allocation or device driver error occurs. Note that you should not call the <a class="el" href="classRtAudio.html">RtAudio</a> destructor if an exception is thrown during instantiation.<p>
-Assuming the constructor is successful, it is necessary to get a pointer to the buffer, provided by <a class="el" href="classRtAudio.html">RtAudio</a>, for use in feeding data to/from the opened stream. Note that the user should <em>NOT</em> attempt to deallocate the stream buffer memory ... memory management for the stream buffer will be automatically controlled by <a class="el" href="classRtAudio.html">RtAudio</a>. After starting the stream with <a class="el" href="classRtAudio.html#a13">RtAudio::startStream()</a>, one simply fills that buffer, which is of length equal to the returned <em>bufferSize</em> value, with interleaved audio data (in the specified format) for playback. Finally, a call to the <a class="el" href="classRtAudio.html#a11">RtAudio::tickStream()</a> routine triggers a blocking write call for the stream.<p>
-In general, one should call the <a class="el" href="classRtAudio.html#a14">RtAudio::stopStream()</a> and <a class="el" href="classRtAudio.html#a12">RtAudio::closeStream()</a> methods after finishing with a stream. However, both methods will implicitly be called during object destruction if necessary.<h2><a class="anchor" name="playbackc">

-The primary difference in using <a class="el" href="classRtAudio.html">RtAudio</a> with callback functionality involves the creation of a user-defined callback function. Here is an example that produces a sawtooth waveform for playback.<p>

-After opening the device in exactly the same way as the previous example (except with a data format change), we must set our callback function for the stream using <a class="el" href="classRtAudio.html#a6">RtAudio::setStreamCallback()</a>. When the underlying audio API uses blocking calls (OSS, ALSA, SGI, and Windows DirectSound), this method will spawn a new process (or thread) that automatically calls the callback function when more data is needed. Callback-based audio APIs (OS X CoreAudio Linux Jack, and ASIO) implement their own event notification schemes. Note that the callback function is called only when the stream is "running" (between calls to the <a class="el" href="classRtAudio.html#a13">RtAudio::startStream()</a> and <a class="el" href="classRtAudio.html#a14">RtAudio::stopStream()</a> methods). The last argument to <a class="el" href="classRtAudio.html#a6">RtAudio::setStreamCallback()</a> is a pointer to arbitrary data that you wish to access from within your callback function.<p>
-In this example, we stop the stream with an explicit call to <a class="el" href="classRtAudio.html#a14">RtAudio::stopStream()</a>. When using callback functionality, it is also possible to stop a stream by returning a non-zero value from the callback function.<p>
-Once set with <a class="el" href="classRtAudio.html#a6">RtAudio::setStreamCallback</a>, the callback process exists for the life of the stream (until the stream is closed with <a class="el" href="classRtAudio.html#a12">RtAudio::closeStream()</a> or the <a class="el" href="classRtAudio.html">RtAudio</a> instance is deleted). It is possible to disassociate a callback function and cancel its process for an open stream using the <a class="el" href="classRtAudio.html#a7">RtAudio::cancelStreamCallback()</a> method. The stream can then be used with blocking functionality or a new callback can be associated with it.<h2><a class="anchor" name="recording">

-When an <a class="el" href="classRtAudio.html">RtAudio</a> stream is running in duplex mode (nonzero input <em>AND</em> output channels), the audio write (playback) operation always occurs before the audio read (record) operation. This sequence allows the use of a single buffer to store both output and input data.<p>
-As we see with this example, the write-read sequence of operations does not preclude the use of <a class="el" href="classRtAudio.html">RtAudio</a> in situations where input data is first processed and then output through a duplex stream. When the stream buffer is first allocated, it is initialized with zeros, which produces no audible result when output to the device. In this example, anything recorded by the audio stream input will be scaled and played out during the next round of audio processing.<p>
-Note that duplex operation can also be achieved by opening one output stream instance and one input stream instance using the same or different devices. However, there may be timing problems when attempting to use two different devices, due to possible device clock variations, unless a common external "sync" is provided. This becomes even more difficult to achieve using two separate callback streams because it is not possible to <em>explicitly</em> control the calling order of the callback functions.<h2><a class="anchor" name="multi">
-Using Simultaneous Multiple APIs</a></h2>
-Because support for each audio API is encapsulated in a specific RtApi subclass, it is possible to compile and instantiate multiple API-specific subclasses on a given operating system. For example, one can compile both the RtApiDs and RtApiAsio classes on Windows operating systems by providing the appropriate preprocessor definitions, include files, and libraries for each. In a run-time situation, one might first attempt to determine whether any ASIO device drivers exist. This can be done by specifying the api argument <a class="el" href="classRtAudio.html#w8w6">RtAudio::WINDOWS_ASIO</a> when attempting to create an instance of <a class="el" href="classRtAudio.html">RtAudio</a>. If an <a class="el" href="classRtError.html">RtError</a> is thrown (indicating no available drivers), then an instance of <a class="el" href="classRtAudio.html">RtAudio</a> with the api argument <a class="el" href="classRtAudio.html#w8w7">RtAudio::WINDOWS_DS</a> can be created. Alternately, if no api argument is specified, <a class="el" href="classRtAudio.html">RtAudio</a> will first look for ASIO drivers and then DirectSound drivers (on Linux systems, the default API search order is Jack, Alsa, and finally OSS). In theory, it should also be possible to have separate instances of <a class="el" href="classRtAudio.html">RtAudio</a> open at the same time with different underlying audio API support, though this has not been tested. It is difficult to know how well different audio APIs can simultaneously coexist on a given operating system. In particular, it is most unlikely that the same device could be simultaneously controlled with two different audio APIs.<h2><a class="anchor" name="methods">

-API Notes</a></h2>
-<a class="el" href="classRtAudio.html">RtAudio</a> is designed to provide a common API across the various supported operating systems and audio libraries. Despite that, some issues should be mentioned with regard to each.<h3><a class="anchor" name="linux">
-Linux:</a></h3>
-<a class="el" href="classRtAudio.html">RtAudio</a> for Linux was developed under Redhat distributions 7.0 - Fedora. Three different audio APIs are supported on Linux platforms: OSS, <a href="http://www.alsa-project.org/">ALSA</a>, and <a href="http://jackit.sourceforge.net/">Jack</a>. The OSS API has existed for at least 6 years and the Linux kernel is distributed with free versions of OSS audio drivers. Therefore, a generic Linux system is most likely to have OSS support (though the availability and quality of OSS drivers for new hardware is decreasing). The ALSA API, although relatively new, is now part of the Linux development kernel and offers significantly better functionality than the OSS API. <a class="el" href="classRtAudio.html">RtAudio</a> provides support for the 1.0 and higher versions of ALSA. Jack, which is still in development, is a low-latency audio server, written primarily for the GNU/Linux operating system. It can connect a number of different applications to an audio device, as well as allow them to share audio between themselves. Input/output latency on the order of 15 milliseconds can typically be achieved using any of the Linux APIs by fine-tuning the <a class="el" href="classRtAudio.html">RtAudio</a> buffer parameters (without kernel modifications). Latencies on the order of 5 milliseconds or less can be achieved using a low-latency kernel patch and increasing FIFO scheduling priority. The pthread library, which is used for callback functionality, is a standard component of all Linux distributions.<p>
-The ALSA library includes OSS emulation support. That means that you can run programs compiled for the OSS API even when using the ALSA drivers and library. It should be noted however that OSS emulation under ALSA is not perfect. Specifically, channel number queries seem to consistently produce invalid results. While OSS emulation is successful for the majority of <a class="el" href="classRtAudio.html">RtAudio</a> tests, it is recommended that the native ALSA implementation of <a class="el" href="classRtAudio.html">RtAudio</a> be used on systems that have ALSA drivers installed.<p>
-The ALSA implementation of <a class="el" href="classRtAudio.html">RtAudio</a> makes no use of the ALSA "plug" interface. All necessary data format conversions, channel compensation, de-interleaving, and byte-swapping is handled by internal <a class="el" href="classRtAudio.html">RtAudio</a> routines.<p>
-The Jack API is based on a callback scheme. <a class="el" href="classRtAudio.html">RtAudio</a> provides blocking functionality, in addition to callback functionality, within the context of that behavior. It should be noted, however, that the best performance is achieved when using RtAudio's callback functionality with the Jack API. At the moment, only one <a class="el" href="classRtAudio.html">RtAudio</a> instance can be connected to the Jack server. Because <a class="el" href="classRtAudio.html">RtAudio</a> does not provide a mechanism for allowing the user to specify particular channels (or ports) of a device, it simply opens the first <em>N</em> enumerated Jack ports for input/output.<h3><a class="anchor" name="macosx">
-Macintosh OS X (CoreAudio):</a></h3>
-The Apple CoreAudio API is based on a callback scheme. <a class="el" href="classRtAudio.html">RtAudio</a> provides blocking functionality, in addition to callback functionality, within the context of that behavior. CoreAudio is designed to use a separate callback procedure for each of its audio devices. A single <a class="el" href="classRtAudio.html">RtAudio</a> duplex stream using two different devices is supported, though it cannot be guaranteed to always behave correctly because we cannot synchronize these two callbacks. This same functionality might be achieved with better synchrony by creating separate instances of <a class="el" href="classRtAudio.html">RtAudio</a> for each device and making use of <a class="el" href="classRtAudio.html">RtAudio</a> blocking calls (i.e. <a class="el" href="classRtAudio.html#a11">RtAudio::tickStream()</a>). The <em>numberOfBuffers</em> parameter to the <a class="el" href="classRtAudio.html#a4">RtAudio::openStream()</a> function has no affect in this implementation.<p>
-It is not possible to have multiple instances of <a class="el" href="classRtAudio.html">RtAudio</a> accessing the same CoreAudio device.<h3><a class="anchor" name="irix">
-Irix (SGI):</a></h3>
-The Irix version of <a class="el" href="classRtAudio.html">RtAudio</a> was written and tested on an SGI Indy running Irix version 6.5.4 and the newer "al" audio library. <a class="el" href="classRtAudio.html">RtAudio</a> does not compile under Irix version 6.3, mainly because the C++ compiler is too old. Despite the relatively slow speed of the Indy, <a class="el" href="classRtAudio.html">RtAudio</a> was found to behave quite well and input/output latency was very good. No problems were found with respect to using the pthread library.<h3><a class="anchor" name="windowsds">
-Windows (DirectSound):</a></h3>
-In order to compile <a class="el" href="classRtAudio.html">RtAudio</a> under Windows for the DirectSound API, you must have the header and source files for DirectSound version 5.0 or higher. As far as I know, there is no DirectSoundCapture support for Windows NT. Audio output latency with DirectSound can be reasonably good, especially since <a class="el" href="classRtAudio.html">RtAudio</a> version 3.0.2. Input audio latency still tends to be bad but better since version 3.0.2. <a class="el" href="classRtAudio.html">RtAudio</a> was originally developed with Visual C++ version 6.0 but has been tested with .NET.<p>
-The DirectSound version of <a class="el" href="classRtAudio.html">RtAudio</a> can be compiled with or without the UNICODE preprocessor definition.<h3><a class="anchor" name="windowsasio">
-Windows (ASIO):</a></h3>
-The Steinberg ASIO audio API is based on a callback scheme. In addition, the API allows only a single device driver to be loaded and accessed at a time. ASIO device drivers must be supplied by audio hardware manufacturers, though ASIO emulation is possible on top of systems with DirectSound drivers. The <em>numberOfBuffers</em> parameter to the <a class="el" href="classRtAudio.html#a4">RtAudio::openStream()</a> function has no affect in this implementation.<p>
-A number of ASIO source and header files are required for use with <a class="el" href="classRtAudio.html">RtAudio</a>. Specifically, an <a class="el" href="classRtAudio.html">RtAudio</a> project must include the following files: <code>asio.h,cpp; asiodrivers.h,cpp; asiolist.h,cpp; asiodrvr.h; asiosys.h; ginclude.h; iasiodrv.h; iasiothiscallresolver.h,cpp</code>. The Visual C++ projects found in <code>/tests/Windows/</code> compile both ASIO and DirectSound support.<p>
-The Steinberg provided <code>asiolist</code> class does not compile when the preprocessor definition UNICODE is defined. Note that this could be an issue when using <a class="el" href="classRtAudio.html">RtAudio</a> with Qt, though Qt programs appear to compile without the UNICODE definition (try <code>DEFINES -= UNICODE</code> in your .pro file). <a class="el" href="classRtAudio.html">RtAudio</a> with ASIO support has been tested using the MinGW compiler under Windows XP, as well as in the Visual Studio environment.<h2><a class="anchor" name="wishlist">
-Possible Future Changes</a></h2>
-There are a few issues that still need to be addressed in future versions of <a class="el" href="classRtAudio.html">RtAudio</a>, including:<p>
-<ul>
-<li>
-Provide a mechanism so the user can "pre-fill" audio output buffers to allow precise measurement of an acoustic response; </li>
-<li>
-Allow the user to read / write non-interleaved data to / from the audio buffer; </li>
-<li>
-Further support in Windows OS for multi-channel (>2) input / output. This is currently only possible with ASIO interface (in large part due to limitations with the DirectSound API). But perhaps a port to the WinMM API should be investigated? </li>
-<li>
-Investigate the possibility of allowing the user to select specific channels of a soundcard. For example, if an audio device supports 8 channels and the user wishes to send data out channels 7-8 only, it is currently necessary to open all 8 channels and write the two channels of output data to the correct positions in each audio frame of an interleaved data buffer. </li>

+<h1><a class="anchor" name="multi">Using Simultaneous Multiple APIs</a></h1>Because support for each audio API is encapsulated in a specific RtApi subclass, it is possible to compile and instantiate multiple API-specific subclasses on a given operating system. For example, one can compile both the RtApiDs and RtApiAsio classes on Windows operating systems by providing the appropriate preprocessor definitions, include files, and libraries for each. In a run-time situation, one might first attempt to determine whether any ASIO device drivers exist. This can be done by specifying the api argument <a class="el" href="classRtAudio.html#w8w5">RtAudio::WINDOWS_ASIO</a> when attempting to create an instance of <a class="el" href="classRtAudio.html">RtAudio</a>. If no available devices are found, then an instance of <a class="el" href="classRtAudio.html">RtAudio</a> with the api argument <a class="el" href="classRtAudio.html#w8w6">RtAudio::WINDOWS_DS</a> can be created. Alternately, if no api argument is specified, <a class="el" href="classRtAudio.html">RtAudio</a> will first look for an ASIO instance and then a DirectSound instance (on Linux systems, the default API search order is Jack, Alsa, and finally OSS). In theory, it should also be possible to have separate instances of <a class="el" href="classRtAudio.html">RtAudio</a> open at the same time with different underlying audio API support, though this has not been tested. It is difficult to know how well different audio APIs can simultaneously coexist on a given operating system. In particular, it is unlikely that the same device could be simultaneously controlled with two different audio APIs.<p>
+The static function <a class="el" href="classRtAudio.html#e0">RtAudio::getCompiledApi()</a> is provided to determine the available compiled API support. The function <a class="el" href="classRtAudio.html#a2">RtAudio::getCurrentApi()</a> indicates the API selected for a given <a class="el" href="classRtAudio.html">RtAudio</a> instance. <HR>

+We open the stream in exactly the same way as the previous example (except with a data format change) and specify the address of our callback function <em>"saw()"</em>. The callback function will automatically be invoked when the underlying audio system needs data for output. Note that the callback function is called only when the stream is "running" (between calls to the <a class="el" href="classRtAudio.html#a9">RtAudio::startStream()</a> and <a class="el" href="classRtAudio.html#a10">RtAudio::stopStream()</a> functions). We can also pass a pointer value to the <a class="el" href="classRtAudio.html#a7">RtAudio::openStream()</a> function that is made available in the callback function. In this way, it is possible to gain access to arbitrary data created in our <em>main()</em> function from within the globally defined callback function.<p>
+In this example, we stop the stream with an explicit call to <a class="el" href="classRtAudio.html#a10">RtAudio::stopStream()</a>. It is also possible to stop a stream by returning a non-zero value from the callback function. A return value of 1 will cause the stream to finish draining its internal buffers and then halt (equivalent to calling the <a class="el" href="classRtAudio.html#a10">RtAudio::stopStream()</a> function). A return value of 2 will cause the stream to stop immediately (equivalent to calling the <a class="el" href="classRtAudio.html#a11">RtAudio::abortStream()</a> function). <HR>

+The <a class="el" href="classRtAudio.html#a7">RtAudio::openStream()</a> function attempts to open a stream with a specified set of parameter values. In the above example, we attempt to open a two channel playback stream using the default output device, 32-bit floating point data, a sample rate of 44100 Hz, and a frame rate of 256 sample frames per output buffer. If the user specifies an invalid parameter value (such as a device id greater than or equal to the number of enumerated devices), an <a class="el" href="classRtError.html">RtError</a> is thrown of type = INVALID_USE. If a system error occurs or the device does not support the specified parameter values, an <a class="el" href="classRtError.html">RtError</a> of type = SYSTEM_ERROR is thrown. In either case, a descriptive error message is bundled with the exception and can be queried with the <a class="el" href="classRtError.html#a4">RtError::getMessage()</a> or <a class="el" href="classRtError.html#a5">RtError::what()</a> functions.<p>
+<a class="el" href="classRtAudio.html">RtAudio</a> provides four signed integer and two floating point data formats which can be specified using the RtAudioFormat parameter values mentioned earlier. If the opened device does not natively support the given format, <a class="el" href="classRtAudio.html">RtAudio</a> will automatically perform the necessary data format conversion.<p>
+The <code>bufferFrames</code> parameter specifies the desired number of sample frames that will be written to and/or read from a device per write/read operation. This parameter can be used to control stream latency though there is no guarantee that the passed value will be that used by a device. In general, a lower <code>bufferFrames</code> value will produce less latency but perhaps less robust performance. A value of zero can be specified, in which case the smallest allowable value will be used. The <code>bufferFrames</code> parameter is passed as a pointer and the actual value used by the stream is set during the device setup procedure. <code>bufferFrames</code> values should be a power of two. Optimal and allowable buffer values tend to vary between systems and devices. Stream latency can also be controlled via the optional <a class="el" href="structRtAudio_1_1StreamOptions.html">RtAudio::StreamOptions</a> member <code>numberOfBuffers</code> (not used in the example above), though this tends to be more system dependent. In particular, the <code>numberOfBuffers</code> parameter is ignored when using the OS-X Core Audio, Jack, and the Windows ASIO APIs.<p>
+As noted earlier, the device capabilities reported by a driver or underlying audio API are not always accurate and/or may be dependent on a combination of device settings. Because of this, <a class="el" href="classRtAudio.html">RtAudio</a> does not attempt to query a device's capabilities or use previously reported values when opening a device. Instead, <a class="el" href="classRtAudio.html">RtAudio</a> simply attempts to set the given parameters on a specified device and then checks whether the setup is successful or not.<p>
+The RtAudioCallback parameter above is a pointer to a user-defined function that will be called whenever the audio system is ready for new output data or has new input data to be read. Further details on the use of a callback function are provided in the next section.<p>
+Several stream options are available to fine-tune the behavior of an audio stream. In the example above, we specify that data will be written by the user in a <em>non-interleaved</em> format via the <a class="el" href="structRtAudio_1_1StreamOptions.html">RtAudio::StreamOptions</a> member <code>flags</code>. That is, all <code>bufferFrames</code> of the first channel should be written consecutively, followed by all <code>bufferFrames</code> of the second channel. By default (when no option is specified), <a class="el" href="classRtAudio.html">RtAudio</a> expects data to be written in an <em>interleaved</em> format. <HR>

+<hr><a name="_details"></a><h2>Detailed Description</h2>
+The structure for specifying stream options.
+<p>
+The following flags can be OR'ed together to allow a client to make changes to the default stream behavior:<p>
+<ul>
+<li><em>RTAUDIO_NONINTERLEAVED:</em> Use non-interleaved buffers (default = interleaved).</li><li><em>RTAUDIO_MINIMIZE_LATENCY:</em> Attempt to set stream parameters for lowest possible latency.</li><li><em>RTAUDIO_HOG_DEVICE:</em> Attempt grab device for exclusive use.</li></ul>
+<p>
+By default, <a class="el" href="classRtAudio.html">RtAudio</a> streams pass and receive audio data from the client in an interleaved format. By passing the RTAUDIO_NONINTERLEAVED flag to the <a class="el" href="classRtAudio.html#a7">openStream()</a> function, audio data will instead be presented in non-interleaved buffers. In this case, each buffer argument in the RtAudioCallback function will point to a single array of data, with <code>nFrames</code> samples for each channel concatenated back-to-back. For example, the first sample of data for the second channel would be located at index <code>nFrames</code> (assuming the <code>buffer</code> pointer was recast to the correct data type for the stream).<p>
+Certain audio APIs offer a number of parameters that influence the I/O latency of a stream. By default, <a class="el" href="classRtAudio.html">RtAudio</a> will attempt to set these parameters internally for robust (glitch-free) performance (though some APIs, like Windows Direct Sound, make this difficult). By passing the RTAUDIO_MINIMIZE_LATENCY flag to the <a class="el" href="classRtAudio.html#a7">openStream()</a> function, internal stream settings will be influenced in an attempt to minimize stream latency, though possibly at the expense of stream performance.<p>
+If the RTAUDIO_HOG_DEVICE flag is set, <a class="el" href="classRtAudio.html">RtAudio</a> will attempt to open the input and/or output stream device(s) for exclusive use. Note that this is not possible with all supported audio APIs.<p>
+The <code>numberOfBuffers</code> parameter can be used to control stream latency in the Windows DirectSound, Linux OSS, and Linux Alsa APIs only. A value of two is usually the smallest allowed. Larger numbers can potentially result in more robust stream performance, though likely at the cost of stream latency. The value set by the user is replaced during execution of the <a class="el" href="classRtAudio.html#a7">RtAudio::openStream()</a> function by the value actually used by the system.<p>
+The <code>streamName</code> parameter can be used to set the client name when using the Jack API. By default, the client name is set to RtApiJack. However, if you wish to create multiple instances of <a class="el" href="classRtAudio.html">RtAudio</a> with Jack, each instance must have a unique client name.

+<h2>Details:</h2>
+
+<a name="1"><sup>1</sup></a>Currently implemented by incrementing a counter every time the tickStream() or callback function is called. If the gettimeofday() function is available (right now it is enabled for all Unix-like systems but not Windows), it also records the time of each tickStream() call. Then, when you call getStreamTime(), it adds the elapsed time since the last tickStream also. This makes the playback counter pretty smooth, but accurate. The intent is that now we could implement something more accurate on platforms that support it - but this is a reasonable baseline. One thing to watch out for: asking OSS for the stream time is problematic; on some devices the counter is only 16-bit and wraps around frequently, and on some devices it will sometimes return bogus values.
+<P>
+<P>
+<a name="2"><sup>2</sup></a>This function could not be implemented for all APIs. If the function returns a value of zero, it should be assumed to be invalid.
+<P>
+<P>
+<a name="3"><sup>3</sup></a>This implementation does not attempt to leave a device as-is. However, the flag <tt>RTAUDIO_HOG_DEVICE</tt> is provided to attempt to grab exclusive use of a device.
+<P>
+<P>
+<a name="4"><sup>4</sup></a>I actually coded this up for OS-X Core Audio. However, I found it bloated the code and presented a number of interface problems that did more harm than good. Thus, it is currently not being considered further (GS).
