Public Methods

Method	Description
AudioBufferMono ( int SampleRate, int Channels ) : System	Prepare an audio frame buffer. Sample rate and channels should match INCOMING signal (from capture device). Always outputs 44.1kHz 16 bit PCM mono audio.
HandleCapturedSamples ( object sender, AudioDataEventArgs e ) : void	Respond to capture event. This should return as fast as possible.
LoadToFrame ( MediaFrame &Frame ) : void	Load the buffer into a MediaFrame for the encoder. IMPORTANT: You must call UnloadFrame after this method is called. For effciency, unload as soon as possible.
RebufferCapturedFrames ( ) : void	Not yet implemented.
RegisterPlugin ( IAudioProcessor PlugIn ) : void
RegisterPlugin ( IVideoProcessor PlugIn ) : void
UnloadFrame ( MediaFrame &Frame ) : void	Release memory previously locked by LoadToFrame()
WipeBuffer ( ) : void	Emergency frame drop. Removes all waiting samples.
WipeBufferUntil ( double AbandonTime ) : void

Private Methods

Method	Description
MergeFirstSample ( ) : void	Join the first two samples together, making a large first sample. Resulting sample retains first sample's timecode.
PrependUnusedSamples ( MediaFrame Frame ) : void	Add unused samples back into the sample buffer. Time stamps need to be properly re-integrated!
ResampleBuffer ( AudioDataEventArgs e, double sample_sec ) : short[]	Error based resampler. Only works for MONO.
ResampleStereo ( AudioDataEventArgs e, double sample_sec ) : short[]	Handles the more complex case of resampling interleaved stereo samples to mono
