Ubuntu: Is there a way to equalize (i.e. drop the bass of) videos?


The Question: I have very bassy speakers, and when I watch videos at night, I either can't
understand the people talking, or have too much bass for my neighbors. Is there
a way to drop the basses of the audio output? Like maybe an audio "proxy", or a
video player with built-in equalizer (like audacious or xmms have for music).
I tried mplayer's equalizer function, but it somehow didn't work.

I usually hate linking to WebUpd8.com because their posts (like too many Ubuntu
user blogs out there) are usually too fast to tell you to add random PPAs and
unknown packages but in this case, they have the best information.
PulseAudio (the sound backend for Ubuntu) supports a system-wide equaliser as
of Lucid. It doesn't provide one but it has the nuts and bolts to let one
transform the audio that passes through PA.
This application was written and released on UbuntuForums but as it doesn't
work for Maverick (due to a broken icon of all things) there's a package built
by WebUpd8 that addresses this:

I wouldn't add their PPA. Not because I think they're somehow evil but because
it'll probably move you to versions of software that we can't support here.
Just download the single deb and double click it.
