+A public method for opening a stream with the specified parameters.

-This method assigns a callback function to a specific, 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#a11">startStream</a>() and <a class="el" href="classRtAudio.html#a12">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#a10">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#a5">cancelStreamCallback</a>() method.

-Exception handling class for <a class="el" href="classRtAudio.html">RtAudio</a>.
+Exception handling class for <a class="el" href="classRtAudio.html">RtAudio</a> & RtMidi.
<p>
-The RtError class is quite simple but it does allow errors to be "caught" by <a class="el" href="classRtError.html#s11">RtError::TYPE</a>. Almost all <a class="el" href="classRtAudio.html">RtAudio</a> methods can "throw" an RtError, most typically if an invalid stream identifier is supplied to a method or a driver error occurs. 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 private <a class="el" href="classRtAudio.html">RtAudio</a> method, error(), which can be modified to globally control how these messages are handled and reported.
+The RtError class is quite simple but it does allow errors to be "caught" by <a class="el" href="classRtError.html#w11">RtError::Type</a>. See the <a class="el" href="classRtAudio.html">RtAudio</a> and RtMidi documentation to know which methods can throw an RtError.

+<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. It was designed with the following goals:<p>
<ul>
- <li>object oriented C++ design <li>simple, common API across all supported platforms <li>single independent header and source file for easy inclusion in programming projects <li>blocking functionality <li>callback functionality <li>extensive audio device parameter control <li>audio device capability probing <li>automatic internal conversion for data format, channel number compensation, de-interleaving, and byte-swapping <li>control over multiple audio streams and devices with a single instance </ul>
-
-<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. When allowed by the underlying audio API, multiple streams can run at the same time and a single device can serve multiple streams. See the <a href="index.html#osnotes">OS 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 (asyncronous) 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.

+<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#a7">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.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.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">

+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.

-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 which can throw a C++ exception be called within a try/catch block.

-<a name="error"><h2>Error Handling</h2></a>
-
-<p>
-<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 within the <a class="el" href="classRtAudio.html">RtAudio</a> class files. 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#s11">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 an invalid stream identifier is supplied to a method or a driver error occurs. 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 private <a class="el" href="classRtAudio.html">RtAudio</a> method, error(), which can be modified to globally control how these messages are handled and reported.

-The <a class="el" href="classRtAudio.html#a3">RtAudio::openStream</a>() method attempts to open a stream with a specified set of parameter values. When successful, a stream identifier is returned. 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 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 only (device = 1 specifies the first identified device, as reported by <a class="el" href="classRtAudio.html#a7">RtAudio::getDeviceInfo</a>()).

-<p>
-The <em>bufferSize</em> parameter specifies the desired number of sample frames which 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 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 href="index.html#osnotes">OS Notes</a> section for general guidelines.

-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.

-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#a3">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. The integer identifier of the opened stream is returned via the <em>stream</em> pointer value. 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>
-Because <a class="el" href="classRtAudio.html">RtAudio</a> can typically be used to simultaneously control more than a single stream, it is necessary that the stream identifier be provided to nearly all public methods. 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#a11">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#a9">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#a12">RtAudio::stopStream</a>() and <a class="el" href="classRtAudio.html#a10">RtAudio::closeStream</a>() methods after finishing with a stream.

-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#a4">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) which automatically calls the callback function when more data is needed. Callback-based audio APIs (OS X CoreAudio 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#a11">RtAudio::startStream</a>() and <a class="el" href="classRtAudio.html#a12">RtAudio::stopStream</a>() methods). The last argument to <a class="el" href="classRtAudio.html#a4">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#a12">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#a4">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#a10">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#a5">RtAudio::cancelStreamCallback</a>() method. The stream can then be used with blocking functionality or a new callback can be associated with it.

+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">

-<a class="el" href="classRtAudio.html">RtAudio</a> for Linux was developed under Redhat distributions 7.0 - 7.2. Two different audio APIs are supported on Linux platforms: OSS and <a href="http://www.alsa-project.org/">ALSA</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. 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 0.9 and higher versions of ALSA. Input/output latency on the order of 15 milliseconds can typically be achieved under both OSS or ALSA 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>
-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 can be achieved with better synchrony by opening two separate streams for the devices and using <a class="el" href="classRtAudio.html">RtAudio</a> blocking calls (i.e. <a class="el" href="classRtAudio.html#a9">RtAudio::tickStream</a>()). The <em>numberOfBuffers</em> parameter to the <a class="el" href="classRtAudio.html#a3">RtAudio::openStream</a>() function has no affect in this implementation. It is not currently possible to have multiple simultaneous <a class="el" href="classRtAudio.html">RtAudio</a> streams accessing the same device.

-<p>
-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.
-<p>
-<a name="windowsds"><h3>Windows (DirectSound):</h3></a>
-
-<p>
-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 (on the order of 20 milliseconds). On the other hand, input audio latency tends to be terrible (100 milliseconds or more). Further, DirectSound drivers tend to crash easily when experimenting with buffer parameters. On my system, I found it necessary to use values around nBuffers = 8 and bufferSize = 512 to avoid crashes. <a class="el" href="classRtAudio.html">RtAudio</a> was developed with Visual C++ version 6.0. I was forced in several instances to modify code in order to get it to compile under the non-standard version of C++ that Microsoft so unprofessionally implemented. Unfortunately, it appears they are continuing to undermine the C++ standard with more recent compiler releases.

-<p>
-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. Therefore, it is not possible to have multiple simultaneous <a class="el" href="classRtAudio.html">RtAudio</a> streams running concurrently with this API. 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#a3">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</code>. See the <code>/tests/asio/</code> directory for example Visual C++ 6.0 projects.

+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.

+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">
