I want to get hold of a free burn-in CD for my new amp. Does anyone
know of a public domain download that can be copied to CD and played?

I am also looking for a similar download file with tones of different
pitch but the same volume to compare left and right speakers.

Yes, I could buy something over the web from the Audiophile /
Stereophile website but I want it today still.

Just use any audio editing package to generate the signals you want
and write them to a CD. I use Goldwave, which is free.

Be careful when burning-in. You don't want to let the magic smoke out.
