Not to be outdone by Google, Meta has released its own AI-powered music generator — and, unlike Google, open-sourced it.
Called MusicGen, Meta’s music-generating tool, a demo of which can be found here, can turn a text description (e.g. “An ’80s driving pop song with heavy drums and synth pads in the background”) into about 12 seconds of audio, give or take. MusicGen can optionally be “steered” with reference audio, like an existing song, in which case it’ll try to follow both the description and melody.  

We present MusicGen: A simple and controllable music generation model. MusicGen can be prompted by both text and melody. We release code (MIT) and models (CC-BY NC) for open research, reproducibility, and for the music community:

Meta says that MusicGen was trained on 20,000 hours of music, including 10,000 “high-quality” licensed music tracks and 390,000 instrument-only tracks from ShutterStock
