It might indeed make sense to apply some kind of normalization based
on dynamic range compression when mixing audio.

The TAP LADSPA plugins contain a supposedly very good limiter. It
might make sense to steal that code (license permitting) and use it in
the PA mixer -- if it doesn't add extra latency.

Patches welcome!
