Stereo Tool is a Winamp plugin that delivers professional quality audio processing.
Have you ever wondered why on the radio all songs have the same volume,
while if you play CDs or MP3s, the volume and the type of sound changes
all the time? That's because the big commercial radio stations use
expensive equipment that ensures that all songs sound the same, and
that they sound good on a wide range of cheap up to expensive audio
systems. Now Stereo Tool offers you similar processing, which you can
use while listening to your own music. Many people have reported that
the processed audio sounds better on their equipment than the original
unprocessed audio. Besides this, Stereo Tool offers a stereo widener
which makes music sound 'fuller' and more 'spacial' (less is also
possible), and it can repair phase shift problems in recordings (cheap
CDs, vinyl, tapes).
