There's Charles Henrich's cdd. Also, Jean-Marc Zucchoni was really active in this field (CD-DA, CD-R) lately. I think his cd-write port also allows reading audio data. Charles will be able to tell you stories about the various problems you encounter when trying to read CD-DA with too cheap drives... it's not that trivial as reading a CD-ROM. CD-ROM data imposes an additional sector address mark along with the ECC bytes. This compensates for crappy mechanics that are poor in following a track continuously. With CD-DA, you don't have this address mark anymore, thusly suffer from the goodwill of the drive (or from jitters if it's actually more of a badwill). > How much do you have to massage the data, once the audio track is > extracted? I.e., any big endian/little endian issues, that sort of thing? Depends on the drive. If you wanna write it with the same drive you've read it before, one would assume you don't have to convert them. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
