5.4.1 Information mp3PRO encoder plug-in
What is ?:
Using advanced technology 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
without a problem on a new mp3PRO player. New mp3PRO files will play
correctly on old mp3 players, however, without the dramatic mp3PRO
improvements. Of course, new mp3PRO files played on a new mp3PRO decoder
will provide the optimal listening experience!
How the mp3PRO technology works:
When making an mp3PRO file, the new 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.
