Hello Brian,
1/ Yes I just used the stock octave-signal package for Ubuntu 12. One
point, in the past I have obtained big speed increases from a local
compile of Octave, I think it's picks up the multiple CPUs.
2/ Re:

Sure, or for the Octave set up instructions maybe even the codec2-dev
README_fdmdv file. Feel free to obtain a Wiki login, I think from
Bruce?
3/ The code below was meant to see if the 3rd arg was a unix pipe
command, if not consider it a text file name. My messy, first pass
command line argument handling, I'm sure there is a better way.
To test with working modem code you could develop/test yr changes with
the codec2 repository, then send me a diff that I can apply to
codec2-dev. Or develop with codec2-dev -r 1639, and send me patches
against that.
codec2-dev$ svn up -r 1639
Thanks,
David
