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.

The Winamp Pro application was developed to be more than just a player. It’s your window to the multimedia world. From MP3s to streaming video, Winamp is the one place you go to feed your audio/video habit. Winamp 5.5 features our new Bento Skin that’s easier to use and more powerful than ever. Easily access the Media Library, Playlist Editor, Video, Visualizations, Media Monitor Browser, EQ, Skin Options and Color Themes all from one single user interface. Includes over 20 color themes that suit nearly every mood or occasion! Winamp 5.5 carries forward the unobtrusive “Window Shade” mode.
