Hi Team.

I was looking for some tips on how to avoid the resonace created when an microphone comes to close with its speaker, and if someone has some tools or maybe a solution on how to address this?

what happens is that when de mic comes to close to the speaker it creates an feedback loop that start to resonate. now the signal coming in from the mic is analog, and goes into the audioboard that is connected to the teensy4
and then goes out from the adioboard to a powered speaker, so basically the audiopath goes straihgt in and out(of coarse low volumes since its just for testing puposses)
so i was wondering what could be done in the teensy-domain to avoid this feedback?

Thanks in advance,
