Loudness / Normalization fix or control

[tommiehansen]

Describe the bug Loudness equalization causes some audio to suffer from be cut off. There is no way to control behaviour.

Expected behavior Be able to set target dbA, in a range ie: 0 (off) +0.5 +1 +1.5 +2 +2.5 +3 +3.5 +4 +4.5 +5

Or be able to tweak the algorithm used for loudness normalization and/or change loudness normalization algoritm to be less prone to cutoffs.
