Pulseaudio equalizer

Mon Mar 22, 2021 4:56 am

I wasn't successful in finding my answer with the search. I am a new user and see that pulseaudio is now the default audio controller in raspberry os. I am using one of my Pi's as a media server and would love to use the equalizer to get the best sound from my soundbar for movies. Thank you for any assistance. I have looked in the bin and not found the equalizer or I don't know what I am looking for.

PulseAudio is a Sound Server which sits atop the ALSA API:

Code: Select all

sudo apt update
sudo apt install pavucontrol pulseaudio-equalizer

Thank you so very much.
I feel like I am in over my head. How do I go about learning what I don't know that I don't know?

I am going to show my ignorance.
I performed the install. I tried to add the equalizer to the main menu. I looked in bin to no avail. What am I looking for and where do I find it?
Thank you in advance.

There is a configuration error in the install of pulseaudio-equalizer.

It would appear PulseEffects is a full featured equaliser, but unfortunately it is not in the Raspberry Pi ARMHF (Raspbian) Operating System repositories:

https://github.com/wwmm/pulseeffects

There are 2 versions of PulseEffects, the current version 5.xx and an unsupported version 4.xx..

Debian Bullseye when released will include the older PulseAudio version 4.8 in the repositories which hopefully will also be included in RaspiOS Bullseye:

https://packages.debian.org/bullseye/pulseeffects

https://github.com/wwmm/pulseeffects/tr ... dio-legacy



Currently I am running Raspberry Pi ARM64 Beta Testing Operating System, which is based of Debian ARM64 and PulseEffects is in the Buster Backports repositories..

I'm running the 32-bit Raspberry OS. Is there a way to run the equalizer program? Is there a backport? Can this be compiled from source? Thank you.

Follow the link I posted above to GitHub page.

You will need version 4.8.5 Source Code:

sudo apt install aptitude
sudo aptitude install pulseaudio-equalizer # Use last option: force install just this package
echo "pactl load-module module-equalizer-sink" >> /etc/pulse/default.pa
echo "pactl load-module module-dbus-protocol" >> /etc/pulse/default.pa
pulseaudio --kill && pulseaudio --start
pactl load-module module-equalizer-sink
pactl load-module module-dbus-protocol
qpaeq # brings up equalizer window with sliders

Equalizer loads up fine, but doesn't affect output. Not sure if this is because it won't affect HDMI sound. Will try with audio out later.

pulseaudio-equalizer does not equate to PulseEffects differing software.

As stated above pulseaudio-equalizer causes compatibility issues for both the OP and myself.

What exactly is the nature of the compatibility problem you're referring to? What are the symptoms?

Didn't the OP and yourself have trouble with the installation of equalizer? I seem to have gotten past that. I can't seem to get it to affect audio output yet, but from your post, that seems to be a different problem than the one you're talking about, unless I'm mistaken?

Since PulseEffects is not a straightforward install, I'm wanting to first explore getting equalizer to work.
