SUMMARY
In many environments (e.g. noisy) a video with wide dynamic range audio is
impossible to listen to; either silent parts are too silent or loud parts get
too loud. A dynamic range compressor (or a compressor/limiter) works by
boosting low volume and/or lowering high volume. This way you can hear a
whisper, and still not damage your hearing by a gunshot in the film. This is
one of the most useful filters a movie player can have.
It would be nice if the "high volume lowering" would actually keep the peaks
where they are, but instead boost everything else, except very low volume. Like
in the attached picture of a top-biased S-curve.
The filter should have at least one setting: the amount of boosting to do.
(Other minor things, like attack, release, and window size, could be hidden as
long as they're at least somewhat sensible.)
