Enhance Audio with equalizer on Arch Linux


Pulseaudio-equalizer is system wide implementation of sound enhancements like bass boosts, echoes, Fidelity, Stereo enhancement and so on.

Audio Video players have their own equalizer but they enhance only the audio / video files they are playing.

So to enhance sounds playing such as: YouTube, facebook, Spotify, System Sound, Chromium, Firefox etc. all you need is the pulseaudio-equalizer.

INSTALLING PULSEAUDIO-EQUALIZER ON ARCH LINUX

  1. install the pulseaudio-equalizer
    $ sudo pacman -S pulseaudio-equalizer
    
  2. install pavucontrol
    $ sudo pacman -S pavucontrol
    
    
  3. Load equalizer module and dbus control
    $ pactl load-module module-equalizer-sink
    $ pactl load-module module-dbus-protocol
    
    

    Load equalizer and dbus module on every boot
    Edit the

    $ sudo nano /etc/pulse/default.pa

    or

    $ nano ~/.config/pulse/default.pa

    file with your favorite editor and append the following lines:

    ### Load the integrated PulseAudio equalizer and D-Bus module
    load-module module-equalizer-sink
    load-module module-dbus-protocol

USING PULSEAUDIO-EQUALIZER

To use equalizer follow these steps below

  1. Play the audio/video file for example play a video in chrom browser
  2. Run PAVUControl by either writing “pavucontrol” in start menu or in console like
    $ pavucontrol
    
  3. Run Equalizer by either writing “qpaeq” in start menu or in console like
    $ qpaeq
  4. On the PAVUControl/Volume Control in the “Playback” tab there would be “Chromium” with a dropdown, select “FFT Based Equalizer…” from dropdown

    I’d like to know why I cant see presets on Manjaro. Also, the GUI is not like the one in te picture. Any help? How can I set a preset? Maybe downloading a configuration file of presets, but where should I introduce de configuration? In wich file? Thanks and sorry for my English

    • Tofeeq says:

      probably you need to un install the equalizer and install it back
      Plus do following if it helps
      $ rm -rf ~/.config/pulse
      $ rm -rf ~/.pulse
      and run it again

    Hi Tofeeq,

    Thanks for a very helpful guide to install an audio equalizer for Arch Linux. Especially for Notebooks (and the like) and/or when listening with headphones, an equalizer greatly improves sound quality.

    The installation as instructed worked without problems.

    To start the application in the console window (bash), enter:

    $ pavucontrol & qpaeq &

    Thus, both programs run in the background (symbol &).

    Best wishes,
    Roland

    Hi Tofeeq, I got this error:

    $ sudo pacman -S pulseaudio
    resolving dependencies…
    looking for conflicting packages…
    error: failed to prepare transaction (could not satisfy dependencies)
    :: pulseaudio-bluetooth: installing pulseaudio (9.0-1) breaks dependency ‘pulseaudio=8.0-3’
    :: pulseaudio-zeroconf: installing pulseaudio (9.0-1) breaks dependency ‘pulseaudio=8.0-3’

    What should I do? Thanks in advance!

    • Tofeeq says:

      It seems like you are installing new version of pulseaudio that is not compatible with bluetooth and zeroconf. Probably removing pulse audio and then installing might solve the problem

    • Roland says:

      “could not satisfy dependencies”

      Is your system up to date?
      Have you switched to another mirror?

      I have (Arch Linux) pulseaudio-equalizer version 9.0-1 installed.

      Do:

      sudo pacman -Syyu

      (with two ‘y’)

      and then try to install again.

    Everyone, the equalizer pictured is in the AUR. It’s called, pulseaudio-equalizer-ladspa. Has the presets and everything. For me this one is better than equalizer 9.0
