SMPlayer Support Forum

Is there any easy way to use a compressor in SMPlayer? Any plugin, or maybe I've overlooked something in Preferences?

no, not in menu

It's not really smplayers fault. MPV changed dynamic range compressor to a really crap version last year.

It's not even worth using and people would just complain it's broken.

here is how to add it.

I tried to get acompressor working as in the link

Edit smplayer.ini, look for [filter_options] and add something like this:
acompressor="level_in=0.5:threshold=0.005:ratio=2"

but I never acheived anything worth using.
acompressor="level_in=0.3:threshold=0.004:ratio=4"
that was the best result I could get before I gave up but the hold and release are wrong and it's very noticeable.
It's extremely frustrating.

Thank you for your response, it's unfortunate that there's no well working compressor in mpv.
For the moment, I found an app, PulseEffects, which is exactly what I wanted, but systemwide. Just for others struggling with the issue.

Thanks for pointing out pulse effects. Needed a reboot.

Compressed it till the level is almost flat. Perfect.

update

pulse effects wasn't stable on my system. It was really nice to set compression and see the resulting output too :/

I switched back to https://github.com/gotbletu/shownotes/b ... ression.md

Ubuntu and others really needs an option for system wide drc built in. It took years for colour temp. Maybe there will be drc in another 10 years
