EQU is a realtime graphical equalizer that will
equalize the audio of almost everything you play through
XMMS (OGG, MP3, WAV, etc.). You can choose four
different band configurations (10, 15, 25 and 31), all of them with ISO central frequencies, independent gain settings
for left and right channels, and more than +-14dB
of gain per band.
It features a skinnable GUI and shadowed mode.
