#define REDBOOK_DIGITAL_AUDIO_EXTRACTION_INFO_VERSION 1

//
// REDBOOK_DIGITAL_AUDIO_EXTRACTION_INFO is a structure which
// defines what the OS believes the abilities of a CD-Rom
// capable drive are with respect to Digital Audio Extraction (DAE)
//
// if Accurate is non-zero, then the drive is able to recover
//     from loss-of-streaming conditions without losing any
//     data.  this means the drive never requires what is commonly
//     referred to as 'stitching' to get a correct audio stream
// if Supported is non-zero, then the drive supports audio
//     extraction.  this field does not suggest any quality.
// AccurateMask0 reports what sized reads (in number of sectors)
//     the OS believes to work.  this field is a bitmask, with the
//     lowest bit indicating single-sector reads, and the high bit
//     indictating 32-sector reads.  if reading a given number of
//     sectors per read gives accurate results, the bit will be a
//     '1'.  if Accurate is non-zero, all the bits should be '1'.
//
