Hi Guys, I designed this protocol since few months ago but it lost in hole of internet. I hope it helps someone. Everyone using video transmitters on UAV/FPV planes and audio channels empty or only transmitting propeller sound, this is why i designed this telemetry protocol on audio ;) Advantages of Audio Telemetry Protocol (ATP) You don't need any extra …

Best method for sending data over a mono audio channel
https://electronics.stackexchange.com/questions/7715/best-method-for-sending-data-over-a-mono-audio-channel
I think RQDQ has the right idea. The best method of sending digital data over restricted bandwidth audio lines is a problem that has already been solved for modems.. The 300 bit/s modems used audio frequency-shift keying to send data. In this system the stream of 1s and 0s in computer data is translated into sounds which can be easily sent on the phone lines.

My A/V transmitter was in the 2.4GHz band and included stereo audio. Over one of those audio channels, I sent telemetry data at 38.4kbps. Over the other channel, I fed audio derived from a prop sensor so I could directly hear changes in engine RPM. I didn't fly FPV, but I did fly at a substantial altitude and distance within visual range.

telemetry link, but note that the only audio channel will be dedicated to telemetry, and cannot be used for an onboard microphone. The Airwave equipment, and clones, provides a high-bandwidth stereo audio link. One of the two channels may be used for telemetry (generally, the Right-Channel), while the other (Left) may be used
New Audio Modem Protocol For FPV Telemetry - RC Groups
https://www.rcgroups.com/forums/showthread.php?1157558-New-Audio-Modem-Protocol-For-FPV-Telemetry
Hi Everyone, I'm designing new audio modem protocol for FPV telemetry over PC. It started for my SimpleOSD XL but i think every OSD can use it. Protocol will very simple and i will share protocol and software with all OSD brands/users, i hope they will use same protocol and someone will write new softwares like googleearth connection or telemetry screens like …

Next step is to get all 4 channels working at the same time, then redesign the board to be compact, and make it able to daisy chain for the ability to record 8, 12, 16+ microphones simultaneously. There will be an SD slot to store the recorded .wav files. Each board costs around $30-$40 to make. Fun.
