Building a comb filter in Pure Data Vanilla from scratch.

A comb filter is a filter created by adding a delayed signal to itself, creating constructive and destructive interference of frequencies based on the length of the delay. All we have to do is delay the signal a little bit, feed it back into itself (predelay), and we get that pleasing, hightech robotic resonance effect.

There's no talking on this one, just building the patch, and listening to it go.
