do a search for "Audio Tools", or "Audio, installation discs" on google... Bass CD's often have some sine waves there too.
If you want to do it on the cheap... Find a Wave Generator/Sine generator program, and record them in .wav format, or any other loss less format. MP3's and other compressed options aren't as good. Then just burn them on a disc.
I have a Bass Mechanik Set that is 2 discs... has all kinds of stuff... I've gont from 20hz to 99hz in .1hz increments, as well as some audio tools like digital blank, white noise, sweeps, and even 10hz & 1hz tones. Never found cd player & amp combo that can play the 1hz tone... but 10hz is a properly tuned Home Theater ported box is WAY COOL.
Digital Black is really cool for finding out how much noise your cd-player & amps add to the signal... play the track, crank it up... and you SHOULD hear nothing... if your equipment has a bad signal/noise ratio however you'll hear noise of some sort (like static). I had an old school sony ES amp back in the day... (Please don't laugh).. It was AWESOME for the signal/noise... thing was SILENT.. I couldn't believe it... problem was it blew a resistor, then some mosfets really easily, it was the Achilles of the amp.
