[maxmsp] [somewhat ot] Importing Audio from CD

Hi,

I never noticed any dropout when importing audio CD, but almost never 
did it with iTunes. To get an audio file from an audio CD, just copy 
the track from the CD to a hard disk, OSX will create an AIFF file for 
you (lathough it may be AIFC, but the conversion is easy).
Peak can also import files from audio CDs.

If you really have to compare audio files, you could use diff in a 
shell (although i'm quite sure there must be some UI versions 
available, I remember there was one on NeXTStep).
