The closest thing COM had to reflection was IDispatch's ability to return ITypeInfo, and. However, it doesn't work as well for unmanaged COM types. Index of the track in the object that created this provider.NET's Reflection API provides rich information about a managed type's properties, methods, and events. The expected playback rate for the sample frames produced by this class. The maximum number of sample frames that can be accumulated inside the internal buffer before an overflow event is emitted. Then the free sample count falls below this threshold, the AudioSampleProvider.sampleFramesAvailable event and associated native is emitted. Number of sample frames that can still be written to by the sample producer before overflowing. Otherwise, the extra sample frames in the buffer will be left unchanged. If true, buffers produced by ConsumeSampleFrames will get padded when silence if there are less available than asked for. The number of audio channels per sample frame.Įnables the AudioSampleProvider.sampleFramesAvailable events. Number of sample frames available for consuming with AudioSampleProvider.ConsumeSampleFrames.
