XAudio2 supports the following PCM formats. 8-bit (unsigned) integer PCM 16-bit integer PCM (Optimal format for XAudio2) 20-bit integer PCM (either in 24 or 32 bit containers) 24-bit integer PCM (either in 24 or 32 bit containers) 32-bit integer PCM 32-bit float PCM (Preferred format after 16-bit integer) The number of channels in a source voice must be less than or equal to XAUDIO2_MAX_AUDIO_CHANNELS. The sample rate of a source voice must be between XAUDIO2_MIN_SAMPLE_RATE and XAUDIO2_MAX_SAMPLE_RATE. Note Data formats such as XMA, {{ADPCM}}, and {{xWMA}} that require more information than provided by <see cref="SharpDX.Multimedia.WaveFormat"/> have a <see cref="SharpDX.Multimedia.WaveFormat"/> structure as the first member in their format structure.
