thought I'd try to cheat WOLF into slower operation by faking samplerates, e.g. -r 80000 -f 22100 gives 2210 Hz audio at 1 bit/second. Looks fine on TX, and RX takes longer as it should, but somehow characters are garbled. Are there other timing parameters or limits inside the engine which do not scale with the samplerate, or could it perhaps be some buffer wraparound? Going faster (-r 4000 -f 1105) worked fine immediately.

Another possibility would perhaps be to use Wolfgang's audio tools (SndInput/SndOutpt) for mixing and decimation.
