Free
Codec Implementations
The VoiceAge R&D team has made fundamental
contributions to progress in telecommunications
by developing numerous audio compression standards
and proprietary solutions based on the ACELP®
technology platform. To accelerate the rollout
and market adoption of these groundbreaking
codec technologies for emerging applications,
we have chosen to offer free codec implementations
that enable the developer community to better
appreciate the strengths and capabilities of
these technologies.
To ensure optimal
dissemination and credibility within the developer
community, VoiceAge is proud to offer the following
free Win32 speech codec implementations through
the
vovida.org initiative originated from Cisco:
In addition to the
vovida open initiative, we offer free downloads
of these codecs for evaluation purposes:
Downloading our AMR-WB+ hi-fi speech and audio
codec enables the multimedia services development
community to experience the excellent hi-fi
audio reproduction capability of AMR-WB+. We
are convinced that developers who take advantage
of this free technology-evaluation offer will
make AMR-WB+ their bandwidth-efficient high-quality
codec of choice.
The ACELP®.net family has already gained
broad recognition. ACELP®.net is the preferred
low bit rate speech codec in both RealAudio®
and Audible®, and it is included in Microsoft
MediaPlayer®. Downloading ACELP®.net
enables developers to rapidly harness this technology
for applications such as broadcast over Internet
(multicasting), multimedia email and multimedia
conferencing.
Contributing
an Implementation to an Open Forum
Various initiatives to support the public exchange
and improvement of source code are currently
being promoted under the open source philosophy.
Such projects are founded on the belief that
the general community has much more to gain
from sharing improvements at the source-code
level through a publicly-owned code base than
from keeping such improvements in private hands.
The source code
published by the standardization bodies is copyrighted
by many organizations and cannot be easily transferred
under a pure open-source license. Consequently,
contributions to open forums are made in the
form of object code, under specific licenses
that place certain restrictions on the object
code but do not prevent the implementation from
being used in harmony with the typical open-source
project licenses.

of one of our free codec implementation licenses,
you will be invited to download the associated
object code to help you move forward with your
evaluation and development processes to help
accelerate solutions to market.
