distressor

I am working on a basic analyzer. Most of it is working fine but i have some trouble with the correlation meter.

I know this has been discussed before and i also found some patches with attempt to do a phase or correlation meter but none of it was working as expected sadly.

I also attached two test files via wetransfer:

The phasing sinus is displayed correctly. I get more or less the same result as spectres as well as logics correlation meter.

The drumloop has some negative spikes that i don't see in spectre or logic. I tried easing the signal but that still doesn't help.

If someone could take a look i would really appreciate it.

correlation

you could use abs~ instead of using the x^2 sqrt~.

It looks like the result is the same.
I'll experiment a little with abs~.
