Uneven sound levels on movies - partial fix I found
I'm posting this topic for people who suffer uneven sound levels when they're watching movies.
Ever since I'm using Linux there was this problem with the sound levels on movies - when the characters speak too quiet or even whisper, the sound goes lower and lower to the point you can't hear anything and you have to increase volume. But by doing so, when the action scenes come and the shooting and explosions begin, the sound is so loud that it could wake the dead.
To that I finally found a fix. Not a 100% fix, though but at least you won't have to fiddle with the volume every 2 minutes. This fix works with VLC (v2.1.x+) and SMPlayer (v18+). It would probably work with other players but these I have and tested it with. So... before I write the fix, you need to check whether you have installed the package libasound2-plugins-extra (this is an additional plugin for ALSA). Without that package the fix won't work (I don't know why, it just won't).
1. Enable equalizer and also check the box to enable it globally.
2. Choose "Party" setting.
For SMPlayer: click the "set as default" setting, then "close" and restart SMPlayer.
For VLC it seems you'll have to do this manually every time you play a movie because VLC 2.1.x refuses to remember the setting. I also have no idea whether remembering the setting will work in VLC 3.x.x cuz I never managed install it but it won't hurt you to try it with 3.x.x.

Re: Uneven sound levels on movies - partial fix I found
Not at all. Having used SMPlayer very little if at all, I had no idea where I might find it. It appears that I don't even have SMPlayer installed on my computer. In VLC, I found the equalizer under Tools, Effects and Filters, but have no idea why an equalizer would affect the dynamic range of an audio source. If in fact it does, perhaps it should be reported as a bug. In VLC, Effects and Filters also includes a Compressor, which, of course, I would expect to affect the dynamic range.

Re: Uneven sound levels on movies - partial fix I found
Idk why it affects it either but you heard it for yourself. Report it, if you wish. The last time I reported an obvious bug with SMPlayer on their forum (a bug with subs and the black horizontal lines you can enable in options - the subs were standing in the middle of the screen, instead of going below the movie image) I was politely told to kiss their arse. Apparently the developers of SMPlayer don't like someone to point them out their own mistakes.
I know about the compressor in VLC but that doesn't change the sound for the better in my case.

I agree. SMplayer has been my default video player for years, since before I installed Linux. I'm not installing that any time soon.

Re: Uneven sound levels on movies - partial fix I found
SMPlayer isn't a stand alone program, it's just a front end for either mplayer or mpv, the latter since Mint 18 in Mint release terms. So it's probably a bug in mpv. Buck passing is a big issue with Linux software since it's so modular and this may just be another example.Valsodar wrote: ⤴Fri Aug 10, 2018 5:42 pm Idk why it affects it either but you heard it for yourself.

I never had that issue with smplayer using mpv but I actually installed mplayer in 18.2 and use that instead. I'm more familiar with mplayer settings and it works as well as mpv if not better (on that machine, YMMV).
Try turning off hardware decoding in SMplayer settings ... I know that sounds counter intuitive but that's actually what the mpv devs recommend. Then test. Then turn off direct rendering and then test again.

Hi Valsodar,
I just read your post and the good replies to it. Here are my thoughts on this as well.
It would help to know more about your system setup. If you run "inxi -Fxzd" from the console terminal prompt, highlight the results, copy and paste them back here, that should provide enough information.
It is not that uncommon for some videos and movies (and music and audio) to have been recorded with varying sound levels. Most of the multimedia players like VLC, SMplayer, etc... and music applications have an option called "normalize" ( a "compressor" filter effect) which tries to equalize the volume to eliminate or reduce highs and lows (and try to increase lower volume and decrease higher volume).
There are other posts in this forum on this topic as well.
You do not need to enable or use the "equalizer" options although you can.
FYI: I have noticed with some music applications that they do not work well if a "normalizer" is used "(enabled)...

Re: Uneven sound levels on movies - partial fix I found
My fix is to go into the movie settings and select Dolby 2.0
Re: Uneven sound levels on movies - partial fix I found
Normalization is always enabled but it doesn't change anything. In fact, when I run a video, it takes too long for the sound to be normalized by the system. The other way to force normalization is to increase the sound level to the maximum and when I hear the normalization kicking in - to turn the volume down.phd21 wrote: ⤴Thu Aug 16, 2018 12:25 pm Hi Valsodar,

Re: Uneven sound levels on movies - partial fix I found
this is my fix for uneven audio levels in linux. this option will conflict with pulseaudio-equalizer-gtk and pulseeffects
1: install
2: go to
3: create blank text and name it
4: copy this script and save
5: run
6: search/replace the script for
7: run
in
by default script will load entry2 compressor+equalizer. you can use sound settings from tray icon or pavucontrol to change entries.
ps: you won't have the echo cancelled entry that's a different script which normalizes your microphone. i'll post the addition maybe later, running these scripts , editing them and finding out how they behave takes some getting used to. listening to music may not sound good, you can use Built-in Audio for that which is audio without the script
1: install
swh-plugins
which are LADSPA plugins that can be used with audacity or audacious as live plugins2: go to
.config/pulse/
folder and delete everything in there but keep presets folder if you have one3: create blank text and name it
default.pa
4: copy this script and save
Code: Select all
#include system-wise config
.include /etc/pulse/default.pa
#compressor -- for normalize audio volume

### pulseaudio -k <<< kill pulseaudio if you make any changes ###

6: search/replace the script for
alsa_output.pci-0000_00_1b.0.analog-stereo
and paste the output from step 5:7: run
pulseaudio -k
which will kill/restart pulseaudio with the new scriptin
pavucontrol
you will now have 3 new entries. entry1 is compressor the entry2 is compressor+equalizer and entry3 is compressor+equalizer+limiterby default script will load entry2 compressor+equalizer. you can use sound settings from tray icon or pavucontrol to change entries.
