FWIW, I've created an enhanced version with support for Speex and CELT
along with a few other bells and whistles. But the need for python to
rebuild the signal chain after every packet is an utter killer which
keeps it from working remotely efficiently. (i.e. back to back packets
with the modem running at the same bitrate as the codec).

Has there been any progress lately on the ability to do synchronous data modes?
