Hiding my love inside a MIDI file!

Hides an audio file inside a vintage MIDI by encoding a recorded MP3 to base64 and stuffing the bytes into unused program‑change bytes and ghost events across MIDI channels, using a browser/JavaScript tool to inject and extract. The demo records an MP3, embeds it into a 90s‑style MIDI, decodes it back to an MP3 file (about 320–329 bytes reported) and plays the recovered audio, so the method demonstrably works.
