But, if sin.wav is a 0.01Hz sine wave, peaking at 1.0 and cos.wav is a 0.01Hz cosine wave peaking at 1.0, then newX.wav = X.wav x cos.wav - Y.wav x sin.wav newY.wav = X.wav x sin.wav + Y.wav x cos.wav are interesting ... ? Cutting and pasting bits of various sin.wav's/cos.wav's/etc. into a 'rotate.wav' and making files for higher orders are left as exercises for the reader ...
