On Windows with my sound driver software I can use reverb effects like "Concert Hall" to add an echo to music.

In Ubuntu 10.10 I use VLC as the player. Is there anyway to add a similar effect? I don't mind a VLC plugin, or an Ubuntu software that makes all output audio as a reverb.

It should be easy to turn on and off. I want this so I can hear my music with different effects, but still want to use VLC if possible.
