Limiter vs. Preamp

[blaubär]

Currently the limiter only limits if and when the final output to the DAC exceeds the maximum allowed value.

It generally doesn't prevent distortion arising from preamp and equalizer.

See the discussions here :

I propose to change this :

The limiter should take action when the output of the DSP exceeds the maximum value, thereby effectively preventing distortions, and that then wouldn't depend on the volume level.

As far as I'm aware, internal processing uses much higher numeric handling (32 bit?) so it should have tons of extra headroom and not normally distort during PA's internal processing. Max could confirm this though.

Whatever - if you switch off DVC and set volume low, you can easily produce distortions that aren't limited by the limiter, see

And maybe that's a feature and not a  bug. That's the reason I created this topic.

( There's another well known MP that already has this feature, there they call it "automatic gain protection",  I take that as an indication that it shouldn't be impossible to realize )
