System wide audio equalizer?

Does anyone know how to install the gstreamer-equalizer?
In which module can I find it?

It should be in the gst-plugin-bad module.
I compiled the csv version of gstreamer and the gst-plugin-bad module, but exaile (svn-version) still says

Gstreamer equalizer is not available. It can be found in gstreamer-plugins-bad (currently found in GTS CSV).

Not sure if this will work for your sound card, works for mine (audigy 2).

Anyway, I just use the ALSA mixer Bass and Treble controls. The thing is that you have to make sure that 'Tone' is also selected, otherwise it has no effect... or is it affect...

Alsa Mixer -->
Edit -->
Preferences --> check 'Tone', 'Bass' and 'Treble' --> close
Back to Alsa Mixer....
Switches Tab --> Check 'Tone' -->
Playback tab --> now your bass and treble sliders should work.

hope this helps.

Are you talking about the terminal program "alsamixer"? How do you get to the edit function?

me three. if I can make fire and cubes show up on the screen with my nvidia graphics card then I ought be able to do something as simple as turn down the bass a little with the nvidia/conexant sound hw.

PulseAudio is a very advanced sound server

i have a fairly old soundblaster live.

took me a while to figure this out, and i'm a tad late but here is my solution:

alsamixer from the command line and set up everything how i like it -- rear speakers louder than the front ones, mic set up as recording device etc.

press m with "tone" highlighted to switch on eq (this is what i hadn't figured out) and adjust bass and treble as necessary.

quit alsamixer and run
alsactl -f ~/.alsactl.state.eq store

run alsamixer again, switch the eq back off, exit. then
alsactl -f ~/.alsactl.state store

now i have sound profiles saved with and without eq switched on. i have the normal one restored at kde startup and then i restore the one with eq to cut the bass at night so as not to piss off my housemate below! the restore commands:

alsactl -f ~/.alsactl.state restore

alsactl -f ~/.alsactl.state.eq restore

i've made a little shell script for each of these commands so i don't have to remember them.

I checked in alsamixer and I don't see a "tone" entry that can be highlighted. Might be hardware specific to the sound blaster?

Yep, me too. My Logitech speakers are great, but way too bassy.

Here's a solution I found while desperately looking around to reduce my bass. I got these instructions from here where someone was trying to fix a sound problem on their laptop.

Type this into the terminal to install C* Audio Plugin Suite

$ sudo apt-get install caps

Create a new asoundrc file

gedit ~/.asoundrc

Insert the following text into the new file:

   pcm.!default {
       type plug
       slave.pcm "equalized";
   }

   pcm.equalized {
       type ladspa
       slave.pcm "plug:dmix";
       path "/usr/lib/ladspa";
       plugins [
           {
               id 1773
               input {
                   controls [ -8 -4 -1 0 0 0 0 0 0 0 ]
               }
           }
       ]
   }

The numbers in the controls array are the equalizer presets
I don't know the range, but I've tested it, and it reduces my bass very well. You need to restart the program using alsa for it to take effect though.
Make sure you keep a backup of your old asoundrc file if it existed.
