NUREMBERG, Germany–Coding Technologies today announced an upgraded release of its
MPEG-4 aacPlus Audio Encoder engine. The company’s aacPlus audio codec
is the audio compression format of choice across a variety of industry
standards, systems and applications, including, MPEG, DVB, DMB, 3GPP.
Coding Technologies’ aacPlus implementations are used by the world’s
most demanding professional equipment manufacturers, broadcasters, and
content aggregators to deliver high quality music via terrestrial,
satellite, the Internet, and mobile networks.Coding Technologies’ enhanced encoder achieves significant
improvements in audio fidelity and listening experience without any
associated increase in bandwidth consumption. This allows content
service providers to “dial-down” transmission bandwidth usage without
affecting or sacrificing established audio quality. These increased
audio quality gains are realized in every application level including:
digital broadcasting, Over-the-Air (OTA) music downloads, high quality
music ring tones and Internet Streaming.

The new encoder enhancements also lead to significantly improved
speech quality and multi-channel audio fidelity at even lower bit
rates. For example, delivering 5.1 Surround Sound now only requires
128 kbps, previous versions required 160 kbps. aacPlus is capable of
delivering CD quality stereo at 48 kbps. In comparison, CD quality for
MP3 is typically rated at 128 kbps.

“Delivering the best audio experience in the most efficient manner
possible is the name of the game,” says Roger Bolton, vice president
of business development at TANDBERG Television where MPEG-4 aacPlus
multi-channel audio is included in the video compression industry
leader’s latest MPEG-4 AVC encoders for HDTV. “The new version of
aacPlus delivers excellent quality and will provide the high levels of
performance our customers require from audio to complement their high
definition video output.”

“At Coding Technologies it is all about audio quality and customer
satisfaction,” says Andreas Ehret, vice president technical lead,
Coding Technologies. “Our team has worked hard and is very proud to
have improved our encoder significantly in these areas as part of this
new release. In short, the world’s best audio codec just got even

The Coding Technologies aacPlus encoder solutions empower some of
the world’s most cutting-edge wireless music and television services
available, including, AOL, KDDI, NTT DoCoMo, REAL, Sprint and XM
Satellite Radio. In the mobile space, Coding Technologies estimates
that the number of aacPlus enabled mobile phones sold worldwide by the
end of 2006 approached 200 million units.

To realize the audio gains of the new encoder no change or upgrade
is required for any installed aacPlus decoder, including those in PC
applications, set-top boxes, mobile phones, and digital music players
or radios.


Coding Technologies’ MPEG-4 aacPlus solutions are available
immediately for Windows, Macintosh, Linux, and selected embedded
platforms. The packages include a variety of libraries, tools, and a
new GUI-based PC sample application, designed to showcase a new
interactive configuration interface within the PC SDK.

The new aacPlus encoders are available as a free upgrade to all
qualified Coding Technologies’ licensees.
