Hi Tasso,

thank you for the suggestion.

This was already reported here:
https://bugs.launchpad.net/mixxx/+bug/1009987

But I am afraid this is not a good solution for your use case.

You can easily have two tracks with the same DB peaks, sounding different
loud.
So a limiter is more to protect your sound systems from peak voltages.
Currently the samples are just clamped at 1. which leads to a bearable
frequency distortion, similar to a bit crusher effect.
A limiter would just reduce the master volume over a period of time.

For the Mixxx decks your use-case is solved by the replay gain analysis.

If you whant to do the same for external sourced like Vinyl Passrough  Aux
or Mic we need a compressor in the input only.

I think we have no such bug, but its similar to:

https://bugs.launchpad.net/mixxx/+bug/1000759
https://bugs.launchpad.net/mixxx/+bug/857450

So I have just filed https://bugs.launchpad.net/mixxx/+bug/1370891

Is it that what you need?  Or do you need something different?

If you like to implement it yourselves, you will receive all the help you
need.
It is just a combination of code sniped that are already in place :-)

Kind regards.

Daniel
