Support of VW / full rate #13

Closed mweyland closed 8 years ago

mweyland commented 8 years ago

The VW mode sends AMBE2+ frames as follows according to the spec:

The transmission rate of the voice signal must be 7.2 kbps or less including the error correction code. Voice encoding follows the standards stipulated for a frame size of 20 ms (144 bit), voice code of 4.4 kbps, error correction code of 2.8 kbps Digital Voice Systems, Inc’s AMBE+2 TM Enhanced Full-Rate (7200 bps).

Check if mbelib supports that. If not, this is probably a lost cause. Also see #12.
