DIY CD ?
I've heard of people making their own CDs by using something like soundforge 4.5 and using some function to make test tones, save them as WAV files and then burn them to a CD.
You could crank out a custom CD with only the stuff you want.
Might be nice to have a CD of this to use on a CD boombox for testing drivers since the amp on a boombox will crank out better than most function generators. Would come in handy for centering during refoam jobs too.
