New drc audio normalisation is not enough

I'm on linux Version: 17.5.0 (revision 8554)

I see the new setting
--af-add=lavfi=[acompressor]

Is there any way to get to work like the old one.

The new one has too much range compared to the old version. The old one really kept the loud sounds quiet and quiet sounds louder. SFX and music is loud.

I actually really need this due to head damage. Loud sounds are very disturbing to me.

TIA

PS. For others on Ubuntu (other linux?), I'm using this at the moment. https://github.com/gotbletu/shownotes/b ... ression.md

The acompressor filter supports many options:
https://ffmpeg.org/ffmpeg-filters.html#acompressor

In smplayer svn r8557 it's possible to pass options to that filter. Edit smplayer.ini, look for [filter_options] and add something like this:
acompressor="level_in=0.5:threshold=0.005:ratio=2"

Thanks.

I've been playing around with it. Not much success yet.

Sound Output is set to Pulse Audio.

If I get it to work, I'll post what I did.
