Finally, sound is smootly and equally distributed over all speakers.
What I noticed is, that now the overall sound volume is much lower. Is there a way to make the whole sound louder as well?
I played around with the equalizer but couldn't make the volume louder.
I don't have a surround configuration, so I'm not certain if there's a better way to solve this problem. The point of equalizer used by this script is not to redistribute volume across speakers.
Anyway, the best way to boost sound is to enable "flat-volumes" in PulseAudio, which will ensure that equalized volume is just as loud as regular audio (at least on my system). Here's the easiest way:
Code:
$ sed 's/flat-volumes = no/flat-volumes = yes/g' /etc/pulse/daemon.conf >~/.pulse/daemon.conf; pkill pulseaudio
Note that the above command will (necessarily) force PulseAudio to restart, so any running sound applications will also need to be restarted.
Re: PulseAudio Equalizer Script
Folks,
I've packaged v1.9 of the script which now includes a GUI interface.
GUI Features:
- 15 equalizer bands available
- ability to change settings without restarting applications;
- ability to permanently save equalizer settings;
- Convenient toggle checkmark to enable/disable the equalizer.
TODO:
- Add more presets (the Flat and Laptop presets work correctly, the Pop preset is not accurate;
- Add ability to save settings as a user-defined preset.
Problems (v1.9)
Unfortunately, although I included a .desktop file in the .deb package, the menu item for the PulseAudio Equalizer will not display. If anybody knows how to help, please get in touch with me (the PackagingFromScratch instructions were of no use).
Until this problem is sorted, you can manually create a desktop link, like so:
- Copy the .desktop file to your own desktop:
Code:
$ cp /usr/share/applications/pulseaudio-equalizer.desktop ~/Desktop/
- Go to your desktop, double-click on the .desktop file, mark as trusted, and then the shortcut will appear properly.
You can grab the .deb from the first post.

Psyke83: Indeed you GUI is a LOT better. In order not to introduce confusion I propose to remove mine. What do you think?
Best regards,

Re: PulseAudio Equalizer Script
Hi Psyke83,
I've seen that in VLC media player the graphic equalizer already has presets (Classical, Reggae, Pop, ....) Maybe you could reproduce the values there.
Best regards,
Steph

The next update will incorporate the VLC presets (though the frequency bands differ, I'll try to compensate) ;).
I plan to make this automatic in a future update, but if you have a setting that you like and want to save as a preset, you can do this:
- Click "Apply Changes" to ensure the setting is saved.
- Run:
Code:
$ cp ~/.equalizerrc ~/.pulse/presets/MyPreset.preset
- The next time you run the GUI, you'll see "MyPreset" in the list.
Edit: fixed since v2.0

I already added the VLC presets (manually) to v2.0.
I'm going to evaluate your files in depth a little later, but I immediately see a problem with the first (Classical) - it seems that the values are inverted... or am I wrong?
Re: PulseAudio Equalizer Script
Note: I've intentionally rounded the values to integer values is it absolutely necessary? If not I can modify the previous attachement.
Re: PulseAudio Equalizer Script
Ooops, yes indeed the signs are wrong for Classical settings. But if you've already done it. There no point for me to correct it.
