Hi Adrian, I've just compiled up the "next" branch and am just trying to figure out how to set it into Codec2 mode
and, which mode. I note on your video, you are using the "QPSK 10K" mode. In my compiled version, I see the "BPSK 1K (700B)" mode, can we have the 700D mode as this is becoming the most common mode? System here: Ubuntu 18.04 LTS on an Asus H110M m/b with a Pentium(R) CPU G4560 @ 3.50GHz, no AVX/AVX2. (I do have AVX/AVX2 on another m/c) Alan VK2ZIW On Sun, 8 Sep 2019 17:47:14 +0300, Adrian Musceac wrote > Hi David, > > Thanks for the kind words! > I had looked at LPCNet before, but on the Mozilla repo when J.M.
