What kind of audio hardware do you own? In particular, will you be using a card like the creative emu10k1? If so, you want tonegen: http://www.lns.com/papers/tonegen/ You run the command, it produces a sine wave sound. Supposing you have multiple-open capable hardware, you can just run multiple copies of tonegen to add harmonics! -- Ross Vandegrift ross@xxxxxxxxxxxx "The good Christian should beware of mathematicians, and all those who make empty prophecies.
