Hi @igorski ,

I am trying to add effects(mostly all the effects) to the input channel during live recording. it produce noise in output file. With out effects output files are smooth(with out noise).

I have attached both without and with effects sample files.

 private ReverbSM reverb;
  reverb = new ReverbSM();
_engine.getInputChannel().getProcessingChain().addProcessor(reverb);

song with effect

Hi @igorski

We noted that noise not only come during addProcessor(). Also some time during normal recording mic produce that noise.

Thanks in advance @igorski

Sounds like your input signal is hot. A little fail safe clamping has been added in b320434 but you might consider adding a Limiter instance to the ProcessingChain of the input channel (as the last effect in the chain).

Hi @igorski ,

Thank you for the fail safe clamping. I have tested in more then 4 device(which causes the noise before) now it's clear and better then before. Once again thank you for your time and effort.
