That does not help with noise, but it sure does with bad levels. I have always wondered if the dynamics compression could not be done at the source. Grüße, Carsten (*) For those with a Mac: Install soundflower and a VST tool of your choice (I use Audio Hijack), run the system audio to soundflower, and run the VST plugin AUDynamics (comes with the Mac) from that to the speaker output you want to use. Configure AUDynamics for an about 40 dB (I’m not joking) knee. Don’t forget to reset system audio to your speaker output when you switch back to a sane audio source…
