Analog modeled audio enhancement. Analog modeled EQ, tube compressors and amplifiers, room simulators and more -- a lot more. As a plug-in for Windows Media Player 9, Winamp 2, and Winamp 3, Ozone adds warmth, bass, sparkle and an overall desirable sound to your MP3s. Unlike other 'enhancers', it does so by modeling the analog characteristics of vintage audio equipment such as tube amplifiers and valve equalizers. So instead of sounding harsh and hollow, your music sounds deep and full.
