A free, open, physical audio format.
"Scan the groove."
Digilog encodes audio into a printable grid of colored dots. Print it on anything. Scan it with any camera. Hear the music. No internet. No servers. No apps to install. No corporation in the middle.
A sticker. A business card. A poster. A tattoo. Anything with a surface can carry a Digilog code.
Scan it with your phone and hear music — a song, a voice, a sound — stored entirely in the dots themselves. No URL. No cloud. The audio lives in the physical object, forever.
The bigger and sharper the print, the better the audio quality. Like vinyl — you get what the physical object can give you.
Independent artists deserve a way to share music physically without depending on Spotify, Apple, or any platform that can disappear, change its terms, or take a cut.
Digilog is for the artist who wants to hand someone music. Literally. A sticker at a show. A card at a market. A tag on a piece of art.
Digilog is and will always be:
- Free to use, implement, and distribute
- Free to encode and decode without royalties
- Protected by GPL v3 — any derivative must stay open
- Owned by no one — not us, not any company, not any foundation
This repository is the public record of that promise. The commit timestamps are the prior art. No patent can be filed on anything described here.
Early specification stage. The format is defined. The encoder and decoder are being built.
See DIGILOG_SPEC_v0.1.md for the full technical specification.

This project is in its earliest stage. If you are a developer, audio engineer, codec researcher, or independent artist who wants to be part of building this — open an issue and say hello.
If you are a corporation seeking to license, patent, or acquire this format — the GPL v3 license already answers you.
