Normalize volume under alsa?

I watch movies in my dorm pretty frequently, but the noise level differences are a real pain. I''m watching Episode I tonight and I have to crank the volume way up to hear the speech, but then way down whenever there''s explosions. Does anyone know of a way to normalize the audio on a movie on the fly? In other words, is there a way to process the audio so that the sound coming out has a constant "loudness" whether it be whispering or ass-whooping? By the way, I''m using the soyo dragon onboard sound, which use the cmipci driver. While I''m at it, it seems that I can''t play more than one sound at once...if I start playing a song with XMMS I can''t start a movie in xine (or any other sound) until I stop it. Is that just a limitation of my sound driver? I don''t want to use arts, because it has a pretty irritating delay on my system. Thanks for any advice.
dunno, I''d say its probably possible, but I''ve never tried. certainly as a plugin for a sound daemon like arts or esd.

arts''s delay can probably be reduced (at some small additional cpu usage cost) there''s probably as sound buffer length that is set to something noticeable like 500ms. I''m sure you can reduce it to 50ms
