SV: CD Mastering Conundrum


You have to use a cd burning software that is capable of burning "disc at
once" and set the silence between the files/programs to "0" seconds.

I was in the same situation as you the other day and I had to move all the
wave files from the studio PC to my Mac Powerbook to let the program Jam
handle the cd burning. I think cd mastering softwares are also crossfading
between the files/programs when burning.
