SpWaveFormatEx BitsPerSample property (SAPI 5.4)

Microsoft Speech API 5.4

Object: SpWaveFormatEx

BitsPerSample Property

The BitsPerSample property gets and sets the bits per sample for the FormatTag format type.

If FormatTag is WAVE_FORMAT_PCM, BitsPerSample should be equal to 8 or 16. For non-PCM formats, this member must be set according to the manufacturer's specification of the format tag.

Note that some compression schemes cannot define a value for BitsPerSample, so this member can be zero.


Set: SpWaveFormatEx.BitsPerSample = Integer
Get: Integer = SpWaveFormatEx.BitsPerSample


  • SpWaveFormatEx
    The owning object.
