PCM Multichannel Stream Data Range

  • Artikel

This example uses a KSDATARANGE_AUDIO structure to describe the data range for a PCM multichannel stream.

  DataRange.FormatSize  = sizeof(KSDATARANGE_AUDIO);
  DataRange.Flags       = 0;
  DataRange.SampleSize  = 0;
  DataRange.Reserved    = 0;
  DataRange.MajorFormat = STATICGUIDOF(KSDATAFORMAT_TYPE_AUDIO);
  DataRange.SubFormat   = STATICGUIDOF(KSDATAFORMAT_SUBTYPE_PCM);
 DataRange.Specifier   = STATICGUIDOF(KSDATAFORMAT_SPECIFIER_WAVEFORMATEX);
  MaximumChannels        = 4;   // max number of channels, or -1 for unlimited
  MinimumBitsPerSample   = 2;
  MaximumBitsPerSample   = 16;
  MinimumSampleFrequency = 5000;
  MaximumSampleFrequency = 48000;
