- * \class PluginInputDomainAdapter PluginInputDomainAdapter.h <vamp-sdk/hostext/PluginInputDomainAdapter.h>
- *
- * PluginInputDomainAdapter is a Vamp plugin adapter that converts
- * time-domain input into frequency-domain input for plugins that need
- * it. This permits a host to use time- and frequency-domain plugins
- * interchangeably without needing to handle the conversion itself.
- *
- * This adapter uses a basic Hanning windowed FFT that supports
- * power-of-two block sizes only. If a frequency domain plugin
- * requests a non-power-of-two blocksize, the adapter will adjust it
- * to a nearby power of two instead. Thus, getPreferredBlockSize()
- * will always return a power of two if the wrapped plugin is a
- * frequency domain one. If the plugin doesn't accept the adjusted
- * power of two block size, initialise() will fail.
- *
- * The adapter provides no way for the host to discover whether the
- * underlying plugin is actually a time or frequency domain plugin
- * (except that if the preferred block size is not a power of two, it
- * must be a time domain plugin).
- *
- * The FFT implementation is simple and self-contained, but unlikely
- * to be the fastest available: a host can usually do better if it
- * cares enough.
- *
- * In every respect other than its input domain handling, the
- * PluginInputDomainAdapter behaves identically to the plugin that it
- * wraps. The wrapped plugin will be deleted when the wrapper is
- * deleted.
- *
- * \note This class was introduced in version 1.1 of the Vamp plugin SDK.
