I wrote that a few years ago...It's a little outdated now. It's faster to use the time stretch dragging function in the AA multitrack or just do time decomal of 32 beats of file "A" divided by time decimal of 32 beats of file B, which will equal the process ratio...Doing the math also works well with ProTools, Waves and Sound Forge.
