Well, when it gets to the point that some beta testing
Nor do I know C that well...
that's why I'm getting the word out - anyone can help spread the word about
Codec2 and its development.
My overt zeal may have ticked a few people off, so I would recommend a more
cooler-headed approach :)

I know a little bit of C, no C++ though.
And I think my knowledge would really not be suffice to do something like
this.

Going strictly from emails I've exchanged with David, it sounds like he has
some "grunt" work in C, which he could offload to someone else to take over
while he focused on DSP programming, etc.
Right on his website he states:
"Not all of this project is DSP. There are many general C coding task
There's also a really great interview with David Rowe, VK5DGR that gives a lot
of background on his history, extensive experience in codecs and his future
aspirations. The interview is from Oct. 2008:

Hi Jim,
you mention using wider bandwidth at VHF but this isn't a realistic option
for use in IARU region 1, where 12.5 KHz channel spacing was adopted back in
1996. It was always worrying that Bruce repeatedly referred to 9K6 data
rates for his DV codec work but wasn't able to demonstrate a metho
Getting 9600 Bd into 12.5 kHz isn't too difficult as long as you're willing to
sacrifice weak signal performance, Shannons law tells us that. I would imagine
OFDM or even m-ary PSK would be capable of providing the required throughput.
The big advantage that GMSK has for manufacturers is that th
Hi Jonathan,
fortunately the AMBE chip is so efficient that we don't have to start
running QPSK/OFDM and changing over to ultra linear PAs, like we have for
Digital ATV. It seems churlish to suggest that everyone change their radios,
repeaters and power amplifiers, just to cope with the deficienc
