ATCD stands for "Audio Trip Choreography Discord".

This repository is not affiliated with ATCD itself: this is a personal project.

Audio Trip is a VR (virtual reality) rhythm game which can help you to do some workout with fun, while "dancing".

PHP backend, no framework, PSR respectful
almost no JS, fast, simple, web basics
Pico CSS fuchsia for the front design
original ats and ogg files are stored into public/files (cf. compose.override.dist.yaml)
no database: all is indexed automatically into a file cache (only a few hundred of songs)
zip files are served on-demand as a pure stream, small memory footprint, thanks to arnapou/zip lib
