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
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!
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.
More Music on your media
Offering 128 kbps (kilo bits per second) performance at a 64 kbps-encoding
rate, mp3PRO 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.
The bottom line is mp3PRO provides superior sound quality at lower
bit rates that traditional mp3..You simply have to experience the difference
for yourself. Download the free Thomson mp3PRO
encoder/decoder and create your own mp3PRO files from your own content
and you be the judge.
