What is MP3Pro?
An MP3PRO encoder splits audio recordings into two parts.
One part analyzes the low frequency band information and encodes it into a normal mp3 stream. This allows the encoder to concentrate on less information and allows it to do a better job of encoding. This also maintains complete compatibility on old mp3 players.
The second part analyzes the high frequency band information and encodes it into a part of the mp3 stream that is normally ignored by old 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. Older, non-mp3Pro decoders will only recognize the first band and will play at a lower quality.
