CDG PLAYER

Playing CDG karaoke files in the browser

A small proof-of-concept for decoding and rendering the MP3+G (CDG) karaoke format entirely client-side. No plugins, no server, no transcoding. Drop in a matching .cdg and .mp3 pair and the page parses the CDG bitstream, paints the graphics to a <canvas>, and syncs it to the audio in real time.

For a full write-up of how the decoder works, the CDG packet format, and the rendering pipeline, see the project on GitHub: github.com/spacestream/cdg-player-mvp.
