I need to make a Carbon application that access to Audio CD tracks.
How can I read the CD data?
If track files appears like AIFC files under MacOS X (TOC appears like
a
file too - ".TOC.plist"), they are empty on MacOS 9, and no TOC... So I
think that I can't use the PBReadForkAsync command...
An idea was to use SCSI or ATA commands to read CD sectors directly...
(Original message below..)
But I can't see carbonized ATA Commands.
It isn't really possible to read red book audio data the same way on 9
as you do on X. The mechanisms used are totally different. On X, the
data is presented via the file system as individual AIFC files. On 9,
you have to talk to the CD driver directly. You will have to have
custom code for each.
