[2005] Producing a Sin Wav - Sound .wav file

I am making a function generator. As of right now, I am simply loading up pre-set .wav files.
I have a file for 5Hz, a file for 10Hz...and so on.


It would be nice If there was a way to actually generate these sounds on the fly, instead of loading them.


My second problem is that when I switch between the files, or stop the sound, there is an audible "click" sound.

Since this application will be used in a car audio environment, this "click" sound could damage a subwoofer at loud volumes.
Any way to avoid this?
