Make sound quality better in ubuntu 9.10(karmic) with PulseAudio equalizer
Posted Under: General
Ubuntu karmic uses pulseaudio as its audio system and if you have a good quality audio card,you can enable surround sound and use equalizer to make sound quality better.
1.First,the installed pulseaudio version is 0.9.19 and need to update to 0.9.21.
Just add “ppa:ubuntu-audio-dev”(without quotes) as a software source in System -> Administration -> Software Sources->Other Software.Reload and it will automatically add the correct PPA and it’s GPG key.(Thanks ARSENDY for the comment)
update and install pulseaudio:
sudo apt-get update
sudo apt-get install pulseaudio
you can use this command to check the pulseaudio version:
pulseaudio --version
2.
Goto System->Preferences->Sound -> Hardware,select your audio card,config->choose Surround or digital output
3.Download the equalizer package from attachment and install it:
sudo dpkg -i pulseaudio-equalizer_2.4_all.deb
you may need to install some dependences which will be list in the output of above command,just use sudo apt-get install package_name to install them.
4.Open equalizer from Applications->Sound and Video->PulseAudio Equalizer,this is a
15-band equalizer.Enable equalizer and set on it.

Something really annoying happens here…
When I enable the equalizer, it turns the audio volume to 100%, is there any workaround this little detail?

As a serious music lover with two sound cards installed on every computer I own, this equalizer makes ubuntu sounds just as good as windows.
The ability to hear changes without having to apply settings would be nice.
Thank you very much.
Now to find a good dj program.

Correction: the config name for apt is /etc/apt/sources.list
Cheers

This mostly worked, but I had to run /usr/share/pulseaudio-equalizer/pulseaudio-equalizer.py from a terminal and send it a ctrl-c after every update. (But instead of quitting, it would perform the update)

If it does not work for you the keyserver “subkeys.pgp.net” just try on this one “keyserver.noreply.org” it works for me. Thanks.
