this seems like something relatively simple to me but i can't find anywhere
that tells me how to do it.

i know i can normalize an actual sound file (such as an mp3 or wma file) but
is there anyway of bypassing this and just normalize the sound coming from
my pc speakers?

obviously i can use the volume control but then if i play a song that is
really quiet - and have to turn the volume up - then if the next song is
really loud then sound out of the speakers will be full blast.

anyone got any help/ideas?

thanks.
