New MP3 Codec Improves Sound Quality at Lower Bit Rates Posted January 10,

Even with the fat hard drives we have today, many people run out of room
storing MP3 files. The situation is much worse for MP3 players that can
only store a very limited amount of music. One way to save space is to rip
the files at a lower bit rate, say 96-kbit instead of 160-kbit or 192-kbit
that some people use. Unfortunately, when you reduce the bit rate, sound
quality suffers. Thompson Multimedia has developed a new digital audio
codec for MP3's dubbed MP3Pro that promises to address that problem.
A new mp3 coding-decoding (codec) format that will provide improved sound
at lower bit rates is now under development for implementation in mid 2001,
Thomson Multimedia announced. The new codec, dubbed "mp3PRO," provides
128kbs performance at a 64kbs encoding rate, nearly doubling the digital
music capacity of typical flash memory. Using lower bit rates, mp3PRO will
also offer Internet radio broadcasters the ability to lower their bandwidth
costs while at the same time offering CD quality in the consumer preferred
mp3 format.
mp3PRO is being developed by Coding Technologies, a company resulting from
the cooperation between a Swedish company that specializes in audio
compression technology and a spin-off from Fraunhofer Institute for
Integrated Circuits. mp3PRO utilizes both Coding Technologies' proprietary
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.
"While the current mp3 format is quite acceptable, our goal is to never
stand still, but to continue to modify the mp3 format to deliver even
stronger audio performance," said Mark Redmond, Vice President, Worldwide
Audio, Thomson Multimedia. "This enhancement to the very popular mp3 format
not only improves sound quality, but compression rates as well."
mp3PRO offers compatibility to both mp3 content and players. Traditional
mp3 content can be decoded by any mp3PRO player. Content coded in the
mp3PRO format can be played back on any traditional mp3 player. However, to
enjoy the quality enhancements of the new mp3PRO format, mp3PRO compatible
players are required.
"Our unique enhancement technology and mp3 are an ideal match," said Martin
Dietz, President of Coding Technologies. "The new mp3PRO offers
significantly increased performance while maintaining the well established
mp3 format. Free from compatibility problems, consumers will fully enjoy
the substantial benefits of mp3PRO."
Backward compatibility with the existing MP3 format is definitely a smart
move. For more information on Thompson Multimedia, visit their website at
