RCA MP3Pro Audio Player

From Overcaster Family:

A player and encoder for the new MP3Pro format. The world's most popular audio compression format gets even better! mp3PRO audio technology is both backwards and forwards compatible with mp3 and creates files that are 1/2 or less the size of original mp3 files, with great sound quality. Developed by Coding Technologies, mp3PRO utilizes both Coding Technologies' codec enhancement technology and the pioneering work in the field of perceptual audio coding covered under the basic mp3 patents owned by Thomson and Fraunhofer. About mp3PRO and compatibility: Using advanced psychoacoustics techniques and music structure analysis, mp3PRO creates files that are more compact than original mp3 files, with equal or better sound quality and complete backwards and forwards compatibility. Your old mp3 files will play completely normally on a new mp3PRO player. New mp3Pro files will play normally on old mp3 players, but without the dramatic mp3Pro improvements. Of course, new mp3PRO files played on a new mp3PRO decoder will provide the optimal listening experience!
