Hey, I've been trying to make a program that shows the frequency and plays it through your PC speaker until it gets to 200000 (humans can't hear passed that). Anyway.. I saw it during physics and thought it would be a cool program to make. Only I've run into a problem. Instead of the a sound it's more like a dull beeb. I want it so that I can do what the physics program did by playing the sound and test how high frequency you can here. I used dos.h's sound(); but that didn't work. If you could help out please that would be greatly appreciated.
