The accuracy of the generated frequencies may depend upon the computer. I would expect the playback of the NAB CD to be reasonably accurate in, say, my Technics CD player (or maybe the Sony car stereo that I use in the shop on a 13.8 volt supply), but I do not know how accurate Audition tones would be. For giggles I should try burning CDs with Audition-generated files on the laptop and the desktop, and then see how accurately those frequencies play back on the computers, the Technics, and the Sony.
