Evidently the "world's first" ecash-transmitted-by-sound was successful 😃 but the sats were lost into cyberspace due to a crash of some sort 😟 So, I just did a second ecash by sound.

See https://stacker.news/items/581840/r/crrdlx?commentId=587259 showing animated gifs of (1) decoding sound (actual audible sound you can hear) and turning it into a text cashu token, and (2) putting it into a cashu.me wallet to receive the sats.

A great "hidden track" to include on an album 😆. Does it work with lossy compression, like standard 128kbps mp3?

Not sure on this, but this illustrates the "next steps" to push things forward:

. Smaller file size

. Mp3

. And as you say "hidden " sounds

. Maybe even sounds that are out of range for human hearing

I don't know what use case might be there, but thus is how we push things forward

Maybe if you first rendered the token as a qr with built in fault tolerance and then turned the qr pixels scanline into sound. Just making shit up

I have no idea what you just said! Lost me at qr pixels...sound. 😀

21x21 pixels in this qr.
