Pitch Playground
A quick and dirty demonstrator for audio interference phenomena.
The five sine-wave oscillators can be tuned independently or linked via arbitrary or preset intervals. The amplitudes can also be independent or linked. A calculator keeps track of the ten possible beat-frequencies that are being generated by the interference between the tones.

Pitch Playground (Mac Intel/PPC)
April, 2008, 8MB with source “patches” for MAX/MSP/Jitter 4.6. (Tested with Mac OS 10.5 Leopard.)
For Snow Leopard compatibility you must install Quicktime 7.
There is no Windows version. If you are a MAX/MSP user and want to compile your own, my download link points to a Mac disk image which you can open with HFSExplorer on Windows. Inside you will find the cross-platform source patches.
