Class SilenceAudioSampleSource

Class for sending silence audio samples. This class sends a block of samples with a value of 0 every 20 milliseconds. Each sample is a 16-bit linear PCM format sample with a value of 0. The AudioSamplesReady event is fired every 20 milliseconds after the Start() method is called.

An instance of this class may be used to send silence to multiple calls. To do this, create a single instance of this class, then call the Start() method once. multiple AudioSource classes can then hook the AudioSamples event to receive the audio samples. Do not call the Stop() method until the application shuts down.
