Hi
I'm using the AudioEffectDelay with a Teensy4 and AudioBoard.
When I change tap times I get pops and clicks. I'm changing a few tap time together (like changing between different presets if that makes sense).
Question is whether this is as expected and if so are there any approaches to minimise the noise?
I've attached some simple code that switches between two sets of tap delay times (it expects some audio input through the audioboard).
Any advice appreciated, Cheers Paul
