- Plextor CD-ROM digital audio extraction for cdrdao
- These patches enhance "cdrdao" with bitwise-exact digital audio extraction
- for "Plextor"-brand CD-ROM drives.
- It uses Plextor vendor unique SCSI command enhancements in order to
- implement this. These features are not known to exist in other
- brand drives (by me, as of 25-3-1999), or to be exploited in any
- other software at this moment.
- Status is alpha, and there are some known bugs and things to do.
- Currently known bugs:
- - Incremental extraction of a CDDA block (by collecting correct samples
- in successive reads of a partly errenous CDDA block) is known to fail
- in some cases (leading to non-unique CDDA extraction).
- Current things to do:
- - Include output formats other than raw (big-endian).
- - Include output to stdio (for on-the-fly application maybe).
- - ...
- Usage hints:
- This clones a CD-DA as exactly as possible (but see known bugs!):
- cdrdao read-cd --device /dev/sga --datafile data.cdr data.toc
- cdrdao write --swap --device /dev/sgb data.toc
- You may want to do a "md5sum" of "data.cdr" on two successive reads
- to ensure the known bug did not occur.
