// 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'.
