Feedback Looper drifts upwards

[ringhof]

I set up a feedback looper which is always engaged and recording.
so that i can feed it with audio and it just plays the loop (resets on trigger)
again and again and i am able to feed it with new audio.

Now to the problem: The audio buffer driffts upwards as long as i
have punch active (see screenshots)

i expected that it piles up on volume more an more as i feed it
with audio but i cant explain myself why it drifts. Any help?
(i use 0.4.26 stable)

Your input probably has a small DC offset. Place a Fixed HPF unit in front of the looper to remove the DC.
