equalizer for ubuntu 11.10

[G.]

Is there a sound equalizer compatible with Ubuntu 11.10?

I added a repository from
https://launchpad.net/~nilarimogard/+archive/webupd8  and I then found
this by searching for equalizer.  Does anyone have experience with
this?

Alsaequal is a real-time adjustable equalizer plugin for ALSA. It can
be adjusted using an ALSA compatible mixer, like alsamixergui or
alsamixer.

Alsaequal uses the Eq CAPS LADSPA Plugin for audio processing, actually
alsaequal is a generic LADSPA plugin interface with real-time access to
the LADSPA controls (the LADSPA plugin included with alsa doesn't allow
for real-time controls) but it was developed for and only tested with
Eq CAPS LADSPA plugin.


Thanks
