Winamp is an audio player that can handle audio CDs, MP3 audio files, and streaming audio broadcasts. It combines extensive functionality with an intuitive interface. Winamp features a playlist editor and a 10-band graphic equalizer with user-definable presets that can automatically load specific files. It also includes Windows Media Technology 4.0 input/output support and the industry-standard Fraunhofer MP3 decoder. This download no longer includes VIS/DSP plug-ins; you can download them separately.

Winamp 3 plays MPEG Layer 2 (MP2) and Layer 3 (MP3) audio streams and Windows Media Audio (WMA), and combines extensive functionality with an intuitive interface. Winamp 3 revamps the entire idea of a skinning system by allowing developers to add entirely brand-new functionality within their own skins.
