I’m trying to take an input file, encode it as qam and dump it to a wav
file.
You know, one of those simple things students do for no reason.
Well, when I try it without a packet_mod_b, the output I get from
my decoder is all 0s, I’m not sure what I expected to happen
without synchronizers, but it doesn’t work. Heh. But that’s
just background.
When I put a packet_mod_b in there, the program freezes and never
only outputs the first 100k of the output wave (buffers
presumably). I think it’s maybe 40k short. I end up hitting ^C
after a while…
Why is it freezing up on me?
