The freedv programs include the modem, if all you want is the codec 2
bit stream:
./c2enc 1300 ../../raw/hts1.raw - | hexdump

I'd like to experiment with piping FreeDV over the network a la DMR and
DSTAR reflectors. First step would seem to be how to extract those
frames from what's coming over the air.
My first testing attempt:
kjotte@daedalus:~/svn/codec2-dev/build$ ./src/freedv_tx 2400B
../raw/hts1a.raw - | ./src/freedv_rx 2400B - /tmp/demod.craw --codecrx
My understanding is that the result of this pipeline would be
/tmp/demod.craw populated with the raw Codec2 1300 frames that were
sent. Instead I'm getting the decoded 8KHz PCM.
What have I missed?
