The new “mp3PRO” audio compression format creates files that are 1/2 or less the size of original mp3 files, and according to the developers achieves “parity or better” in terms of quality with the Windows Audio 8 format developed by Microsoft.
The new mp3PRO encoder splits audio recordings into two parts, one analyzes the low frequency band information and encodes it into a normal mp3 stream, thus preserving backwards compatibility with current mp3 players. The second part analyzes the high frequency band and encodes it into a part of the mp3 stream (that is ignored by current mp3 decoders). New or upgraded mp3PRO decoders will tap into this part of the stream and put the two bands back together, resulting in the full audio bandwidth.
