<H1>Open Source Digital Voice Codec</H1>
<P><FONT face=Tahoma><STRONG>David Rowe VK5DGR</STRONG> has released V0.1 alpha
of <STRONG>Codec2</STRONG>, a fully function 2550 bit/s codec for Amateur Radio
digital voice.</FONT></P>
<P><FONT face=Tahoma>Codec2 is an open source low bit rate speech codec designed
for communications quality speech at around 2400 bit/s. <STRONG>Applications
include low bandwidth HF/VHF digital radio. It fills a gap in open source,
free-as-in-speech voice codecs beneath 5000 bit/s</STRONG>. It is released under
the GNU Lesser General Public License (LGPL).</FONT></P>
<P><FONT face=Tahoma>The lack of a copyright free Codec has impeded the
development of Amateur Radio Digital Voice communications at both HF and VHF. It
is hoped Codec2 <STRONG>will eventually be incorporated into DV software such as
WinDRM and FDMDV</STRONG> which had relied on a non open source
Codec.</FONT></P>
