The Audio Toolbox is an audio function generator for the Mac. Using no additional hardware, you can produce sine, square, triangle, and sawtooth waveforms of any frequency up to 22 kHz, as well as generate noise. It can be used to create all sorts of cool sound effects. You have full control over the frequency, type and volume of each sound produced.
