Equalizer for Pulse Audio

There’s a really cool equalizer for Pulse Audio which can be installed by adding a repository. Its a system wide equalizer hence no matter what media player you use, you will be able to utilise this setting.

The image below is a screenshot of the same:

How to install:

Open the Terminal (Accessories > Terminal) and type in the following:

sudo add-apt-repository ppa:psyke83/ppa

Next type the following in the Terminal:

sudo apt-get update

Finally, type the following (in the Terminal of course)

sudo apt-get install pulseaudio-equalizer

Thats it. You can access the Pulse Audio Equalizer from the Sounds & Video menu.

Update: The creator of this Equalizer has added a new .deb file for both 32 and 64 bit versions of Ubuntu 10.10, simply click on the following link and install: Download Link

    To make it work in Meerkat:

    1. Follow all the steps described above

    2. Edit psyke83-ppa-maverick.list and
    change “maverick” to “lucid” in both of the two lines

    $ sudo pico /etc/apt/sources.list.d/psyke83-ppa-maverick.list

    3. Copy the missing icon

    $ sudo cp /usr/share/icons/Humanity/apps/16/gnome-volume-control.svg /usr/share/icons/hicolor/16×16/apps/gnome-volume-control.svg

    Executing from Applications/Sound & Video/PusleAudio Equalizer gives nothing.

    Executing from Terminal gives the following:

    dennis@PC:~$ pulseaudio-equalizer-gtk
    Getting settings…
    ls: cannot access /home/dennis/.pulse/presets/*.preset: No such file or directory

    Typical for Linux…so…what next?

        I have exactly the same problem, giving exactly the same error message. I have re-installed and re-installed and re-installed, to no avail. I am running Maverick and have followed the procedure as given by Kenneth Freeman above, still no luck. Any other suggestions?

    I’m trying to get the equalizer enabled by default at startup. I’m running 10.04. I’ve tried adding the following entry to the Startup Applications:

    Command: pulseaudio-equalizer enable

    However, this isn’t working.

    I also tried adding sudo pulseaudio-equalizer enable to my etc/rc.local script to no effect.

    I’m a Linux n00b, so does anyone have a better way to do this?

    Thanks.

    pulseaudio-equalizer is already in Fedora’s repos. Ubuntu should keep up.

        but still no effect. can somebody help me?

        i noticed something, the pulse audio equalizer doesn’t work with an input sound & in real time recording (equalizing the input sound of an electic guitar) or whatever it called but it only works with output sound & when i played a recorded sound (like playing music) or playback or whatever it called… is there anything that can equalize any input sound in real time or during recording so the input sound (from electric guitar or something) is equalize or clean during recording? (i don’t know how to use JACK)

    Is there any way to make this work when playing music through spotify?

    So far spotify stops everytime I change anything in the equalizer program.

    HEY! It works WITHOUT GRAPHICAL INTERFACE!
    Got the same problem:
    pulseaudio-equalizer works (terminal)
    pulseaudio-equalizer-gtk works not (terminal or menu)

    In that case, go to /home//.pulse/equalizerrc
    and modify the 1.0 in the file, right below “Multiband EQ”, this is the master volume.
    restart the EQ via terminal:
    pulseaudio-equalizer disable
    pulseaudio-equalizer enable

    Done!

      Awe, man!!!
      between home//.pulse
      there’s the username (your home-folder)

      I set “username” in “less than”-“greater than”-parentheses and they were removed automatically. :'(
