Flanger - Pure Data Part 2

This is part two of this series on creating audio effects using Pure Data. If you haven't yet, check out last weeks tutorial on creating chorus effects, then come back to complete this one. This week we'll be turning our chorus effect into a flanger.

Famous for rock guitar riffs like Barracuda by Heart, flanger is a swooshing guitar effect some people liken to a strong sounding phaser, however they are built differently.

The flanger effect differs from chorus due to it's use of a feedback loop and shorter delay times of up to 10ms, rather than around 10-40ms for chorus. For two very different sounding effects they are built very similarly. 

Below is a pure data patch for flanger. You'll notice that it is very similar to the patch from last week's post, demonstrating the small technical differences between chorus and flanger. Why not give it a go and see what kind of effects you can create!

Hint: By increasing the delay time you decrease the pitch of the effect, and decreasing the delay time increases the pitch.
