What would be a good way to encode Video, Images or even digital information as audio files that can be recovered using a microphone or audio line-in? I'm aware of SSTV for Images, which works really nicely but surely people might have worked on more complex modulations just for the sake of it? So far I've tried Trellis Modulation and SSTV, which works pretty nice but how far can we push it in terms of efficiency.

I'm new to this but a fast check on wikipedia tells me SSTV is uses radio frequencies as a medium, not sound.
Technically you can use any wiless protocol with sound as a medium, thoug you will have huge constrains on latency and throughput, probably big error-rate and won't get the signal very far. It's an interesting experiment noneteless. Maybe we could try to implement wifi on it (and send any data using normal internet protocols)

You mean like fiberoptics?

Wow
Imagine that
Modulating data in such a way that it can be transferred as analog sound
Surely this is not a thing
Image also de modulating it again as data
Wow
A MoDem
Surely this cannot exist

I've tried it with sound and it works fine. There's an SSTV decoder app for smartphones. Just go to a YouTube video that's SSTV encoded and place your phone next to your speakers. Works pretty well.
We were thinking about encoding some information on a Vinyl for our hackerspace as a silly project and that got me thinking how much of data can I squeeze onto a disc that allows up to 7 minutes of audio on both sides.

No

You catch on quick.
