Module voice 

D-STAR voice frame types and constants.

Each voice frame carries 9 bytes of AMBE-encoded audio and 3 bytes of slow data. Frames are transmitted at 50 Hz (one every 20 ms) per the JARL D-STAR specification. A superframe is 21 frames (frame 0 is sync, frames 1-20 carry slow data) for a total of 420 ms per superframe.

See g4klx/MMDVMHost/DStarDefines.h:44 for NULL_AMBE_DATA_BYTES (the AMBE silence pattern).
