mp3PRO is both backwards and forwards compatible with MP3 and creates files that are 1/2 or less the size of your original MP3 files, with even greater sound quality.

mp3PRO offers 128 kbps (kilo bits per second) performance at a 64 kbps-encoding rate, which doubles the digital music capacity of flash memory and of compact discs. For example, traditional audio CDs hold about 15 songs, and an MP3 CD can hold 150 or more songs encoded at 128 kbps. In the near future, when MP3 CD players incorporate the mp3PRO decoder, consumers will be able to store over 300 songs on an mp3PRO encoded Compact Disc.
