Moiré Waves

I was playing around with some additive synthesis in Python, generating various basic waveforms and checking them visually, in Soundtrack Pro.

The moiré pattern of the waveforms in one test file was interesting:

That's actually 220 cycles of a sine wave, followed by the same for a sawtooth, square and triangle waveform.

Any plans to post code? I like the idea of programatically generating sound.

I'll open source it soon.

Note: in pure Python, it's way slower than real time :-)
