Remarks
Obtains the size in bytes of the WAVEFORMATEX data structure that describes the format of the given ACM codec.
The WAVEFORMATEX data structure that describes the given format can be obtained using the EncodeFormats.ACM.GetCodecFormatWavData method.
For further details about using the Windows Audio Compression Manager refer to the EncodeACM class section.
For a tutorial about the use of the Windows Audio Compression Manager refer to the How to use the Windows Audio Compression Manager section.
For further information about available encoding formats see the EncodeFormatsMan class.
