"Judy" read this in the National Enquirer :
You need to open it up in Peak, and either highlight the part you want and
make a new doc from selection, or highlight the part you want gone, and
erase it. Probably better off making two new docs from the different parts
and saving the two as well as the original. Then they will be 3 aiff files.
Just drag those files to Toast in the Finder and burn away as AUDIO.
Jam isn't needed for this. If you wanted to simply use the whole 20 minute
shebang and put markers in with Peak, and save that as a Jam file. Thatıs
the only way I know of making a single long file into several ones while not
actually separating it into many smaller files. The Peak/Jam method is best
for dropping indexes into a long continuous material like a piece of music,
live show with segueing songs, etc. Otherwise, taking a single file and
cutting out sections and saving as new files works fine if the timing can be
broken up without harming the program (cutting an LP into the constituent
songs from a single 45 minute capture).
