I haven't tested it on that particular hardware but I think it might be feasible. Some modem profiles are more computationally expensive than others, and receiving is more expensive than transmitting.
At some point I'd like to try it on an RPi across a piezo and a cheap mic
- mschuster91 10y agoYou could try making a "real" C library (with proper Makefile etc) out of it and compile it on a Pi, with a pulseaudio (or ALSA) configured to do loopback (i.e. route the audio output to the line-in input).
- brian-armstrong 10y agoWay ahead of you ;) https://github.com/quiet/quiet-lwip https://github.com/quiet/quiet-lwip In fact, the Android library is just a wrapper on this, although a fairly non-trivial one. libquiet's tests actually run exactly as you describe on a loopback alsa device
