This evaluation software is for personal and non-commercial use and intended to demonstrate the MP3 Surround technology available at Fraunhofer IIS. MP3 Surround provides a multi-channel listening experience with a minimum of extra bitrate and maximum compatibility.

What is MP3 Surround?

MP3 Surround is a format for storing compressed multi-channel audio material. It allows encoding multi-channel sound data in high quality at bit rates comparable to those currently used to encode stereo material. Most important, the new format is completely backward compatible to existing stereo MP3 software and devices.
