hey guys

i'm looking for some suggestions on how to test my project to see if its working the way i think (and pray) it is. i have 3 filters with center frequencies of 110 khz, 440 khz, 1760 khz. my first thought is to use a signal generator but i dont have access to one. does any one know where i can:
 1) get access to a signal generator
2) find some kind of musical tuning instrument that generates these notes

just have your computer play the tones. You can generate them with a
couple of different programs, including Audacity, which is free.
