Get in the Mix: Creating a comb filter and a flange effect

“

So far we've talked about how constructive and destructive interference leads to cone filtering. Let's see how we can make musical use of this. The cone filter frequency response represents a radical reshaping of tone. Modulating that cone filter gives us flanging. All we need is a track and a short delay. Plugins with the word flanger in their name typically provide us delay processors with a single short delay accompanied by all the usual parameters. Feedback, filtering, polarity reverse, and modulation capability. Electric guitar offers a great opportunity for the flanging effect. Recall that flanging comes from the mixing of a signal with a very short delay. It's most pronounced at very short delay times. One millisecond or less. But the effect remains audible up to as much as 15 or 20 milliseconds. Adding flange transports the guitar texturally, spectrally, and it might even transport us a bit back in time. Back to the 60s, when rock and roll guitarists first introduced us to the…
