ggwave VS minimodem

Tune in for mostly mellow music and data! MFSK64 text/image + two burts of GGWave data: https://github.com/ggerganov/ggwave

Yes indeed, I'm using Rogue Master 0.63.2-0728-RM-T. In a gist, I'm creating files containing monotone sound signals created by ggwave. However, by default ggwave writes 16-bit WAV files, and playing these is neither supported (it's mentioned in the code) and results in pretty garbled output. But I get output.

This will get you started:

Tony Fisher wrote V.32 soft modem stack for SGI Indy back in 1996. York University couldnt handle hosting whole 8 megabytes of his stuff https://www.cs.york.ac.uk/news/fisher/home-page but at least they had the decency to upload it to github instead of just deleting https://github.com/university-of-york/cs-www-users-fisher/tr... Randy Rossi rewrote this project and got working V.21/23 https://github.com/randyrossi/fisher-modem

Fabrice Bellard, because of course he did :), implemented his own version all the way to V.34 with parts of V.90 https://bellard.org/linmodem/

V.21 modem implemented in Gnu Radio https://web.archive.org/web/20170627151353/http://aaronscher...

amodem - good source of ready made modulation implementations https://github.com/romanz/amodem

minimodem- simple radio link FSK modem https://github.com/kamalmostafa/minimodem

audsl - leased line project, not compatible with standard modems https://www.araneus.fi/audsl/ but might give some ideas.

Try downloading it from the tags section instead of cloning the repo. https://github.com/kamalmostafa/minimodem/tags

there's a tool called minimodem http://www.whence.com/minimodem/ it uses audio cards to replicate ancient modem standards - I was watching videos of old modems and was able to use minimodem to simultaneously reconstruct the terminal session locally. It was amusing to do so.

“What do you do when you cannot copy text between computers due to lack of internet connectivity? “

Literally what Minimodem was created for :)
