Audio Data Formats and Data Ranges

Audio drivers use the KSDATAFORMAT and KSDATARANGE structures to specify audio stream formats:

  • The digital format of a KS data stream is specified by a KS format descriptor that begins with a KSDATAFORMAT structure.

  • The range of stream formats that a KS pin can support is specified by an array of KS data ranges; each array element is a range descriptor that begins with a KSDATARANGE structure.

For more information about these two structures, see KS Data Formats and Data Ranges. For more information about KS data ranges, see Data Range Intersections in AVStream.
