Redefining the Communication Experience: Fraunhofer IIS Makes Full-HD Voice Available for VoIP Apps
ERLANGEN, Germany --(Business Wire)--
Fraunhofer IIS (News - Alert), the world's renowned source for audio and multimedia
technologies, will showcase how its Full-HD Voice codec, Enhanced Low
Delay AAC (AAC-ELD), supercharges the communication quality of any VoIP
app, be it for smartphones, tablets or televisions at CES (News - Alert) 2013.
Natively supported in iOS and Android, the AAC-ELD codec is now readily
available to app developers and service providers to offer superior VoIP
applications that run at the Full-HD Voice quality level. This delivers
a completely new same-room communication experience to the end-user.
"From mobile phones to TVs, consumers expect the highest audio quality
from their entertainment experiences. There is no reason the
expectations for VoIP communication should be any different," said
Harald Popp, head of the Multimedia Realtime Systems department at
Fraunhofer IIS. "By providing developers direct, native access to the
best codecs to deliver Full-HD Voice VoIP apps, consumers can expect the
best quality possible."
Fraunhofer's Full-HD Voice technology is already widely used to provide
CD-like audio quality for professional video conferencing systems, as
well as consumer video telephony applications, such as apple FaceTime (News - Alert).
With AAC-ELD now available in iOS and Android, this same level of
professional communication quality can be readily deployed in consumer
App developers can access the natively-integrated AAC-ELD codec through
the Fraunhofer FDK Codec Library in Android (News - Alert) since version 4.1 and in iOS
since version 4.0 as well as in OSX, allowing cross-platform deployment
of Full-HD Voice.
Background Information on Audio Quality in Communication Systems
Historically, the audio quality of VoIP services has been similar to
legacy telephony, with a maximum audio bandwidth of 3.4 kHz. Recently,
some services have offered a higher audio bandwidth of 7 kHz, which is
stillquite limited compared to 20 kHz which is the maximum bandwidth
humans are able to hear. Another reason for the limited audio quality of
phone calls is usage of speech codecs. As their algorithms emulate a
single human vocal tract, they are only optimized for a single speaker
in a quiet environment. Speech codecs do not deliver other signals
clearly, such as ambience sounds, music and background noise. The result
is compromised audio quality in conversations and highly distorted
background sounds or music.
With the state-of-the-art MPEG-4 communication codec AAC-ELD, app
developers can easily offer a level of performance that removes the
limitations of speech codecs and offers the full audio bandwidth of up
to 20 kHz, giving voice, music, and ambience sounds equal treatment.

The Fraunhofer IIS Audio and Multimedia division, based in Erlangen,
Germany, has been working in compressed audio technology for more than
20 years and remains a leading innovator of technologies for
cutting-edge multimedia systems. Fraunhofer IIS is universally credited
with the development of mp3 and co-development of AAC (Advanced Audio
Coding) as well as technologies for the media world of tomorrow,
including MPEG Surround and the Fraunhofer Audio Communication Engine.
Through the course of more than two decades, Fraunhofer IIS has licensed
its audio codec software and application-specific customizations to at
least 1,000 companies. Fraunhofer estimates that it has enabled more
than 5 billion commercial products worldwide using its mp3, AAC and
other media technologies.
The Fraunhofer IIS organization is part of Fraunhofer-Gesellschaft,
based in Munich, Germany. Fraunhofer-Gesellschaft is Europe's largest
applied research organization and is partly funded by the German
government. With 20,000 employees worldwide, Fraunhofer-Gesellschaft is
composed of 60 Institutes conducting research in a broad range of
research areas. For more information, contact Matthias Rose, email@example.com,
