Wow and Flutter: A Starting Template
Caveat: I’m not a studio engineer. Parameters and starting points are derived from real world data, but they are just starting points. I’ve tried to give you enough controls to shape the effect to your liking, along with some qualitative descriptors for depth (professional to walkman) and flutter rate (roughness to blur).
Flutter: Three cosines at starting rates of 7, 11, 17 hertz with weighted mixing; light phase drift; and moderate random amplitude modulation.
Wow: A fixed 0.1 hertz cosine with very slow random amplitude modulation.
Let me know if I need to fix anything.
For a tapin~ based delay, multiply your delay time by this patch's output signal.
For a groove~ delay, multiply your playhead rate (as signal) by this patch's output.
For a play~ delay, multiply the rate of the phasor~ driving your playhead.
