PCM Stream Data Format

  • Article

This example uses a KSDATAFORMAT_WAVEFORMATEX structure to describe the data format of a PCM stream.

  DataFormat.FormatSize  = sizeof(KSDATAFORMAT_WAVEFORMATEX);
  DataFormat.Flags       = 0;
  DataFormat.SampleSize  = 0;
  DataFormat.Reserved    = 0;
  DataFormat.MajorFormat = STATICGUIDOF(KSDATAFORMAT_TYPE_AUDIO);
  DataFormat.SubFormat   = STATICGUIDOF(KSDATAFORMAT_SUBTYPE_PCM);
 DataFormat.Specifier   = STATICGUIDOF(KSDATAFORMAT_SPECIFIER_WAVEFORMATEX);
  Format.wFormatTag      = WAVE_FORMAT_PCM;
  Format.nChannels       = 2;
  Format.nSamplesPerSec  = 44100;
  Format.nAvgBytesPerSec = 176400;
  Format.nBlockAlign     = 4;
  Format.wBitsPerSample  = 16;
  Format.cbSize          = 0;
