Question

using C or python (python preferred), How would i encode a binary file to audio that is then outputted though the headphone jack, also how would i decode the audio back to binar

Answer 1

If you're looking for a library that does this, I'd recommend libquiet. It uses an existing SDR library to perform its modulation, and it provides binaries that will offer you a pipe at one end and will feed the sound right to your soundcard using PortAudio at the other. It has GMSK for "over the air" low bitrate transmissions and QAM for cable-based higher bitrate.
