Ussing easyeffects with a retrogaming distribution

[albmm74]

Hi friend.

I'd like to use easyeffects to normalize the sound output in a retrogaming distribution based on Ubuntu 22.04, to get most emulators/games sound at more o less the same volume.

Could this be possible? Does it work in realtime?

Thanks in advice.

to get most emulators/games sound at more o less the same volume.

For my personal needs the autogain plugin in EasyEffects is enough. But you may also want to take a look at presets like https://github.com/Digitalone1/EasyEffects-Presets/blob/master/LoudnessEqualizer.json that are more aggressively changing the audio dynamic range.

Does it work in realtime?

The plugins work in a realtime thread configured by PipeWire. If the system will be able to keep up it will depend on how powerful it is.

Many thanks.

Considering I need only this feature, what are the minimal plugins/dependencies I need to install?

Thanks again.

I do not think there is room to save a lot of space. The autogain is a built-in plugin that is complied with EasyEffects. Not way to disable it for now. Most of the other plugins are from Calf or Linux Studio Plugins. The preset in the link uses plugins from Linux Studio Plugins. So you need it if you want to try that preset.

Thanks again friend, but I can compile it on Ubuntu 22.04, getting a message saying libportal-gtk4 is not present; tried to install libgtk-4-dev broke my distribution...

I found a version of pulseeffects in the oficials ubuntu repositories, could be valid for my propossal?

UPDATE: working good with your recomended digitalone preset. Many thanks!

One solution to consider when the distribution does not provide the packages for a native EasyEffects build is using the Flatpak package https://github.com/wwmm/easyeffects/wiki/Package-Repositories#flatpak.

Thanks Wellington.

Really testing it slowly it is not working as I want, I think due the digitalone profile do not use autogain, and some old arcade (MAME) games do not raise its volumen levels, what is what I want.

Appart of this, launching pulseeffects on a terminal I get the rnnoise plugin error, and I do not get it working with the -w option to hide the windows (and really I need it be hide when I launch it from .xinitrc file).

Can you help me?

Thanks in advice.

In this case it is probably better to start it with the command line option --gapplication-service so that it doesn't even show its window and start in service mode.

I got this message from terminal launching pulseeffects --gapplication-service :
