AudioCraft
Best for prototype music and sound effects, non-commercial.
Meta's research library bundling MusicGen for text-to-music, AudioGen for text-to-sound-effects, plus EnCodec, MAGNeT and related models. A solo maker can prompt background music by mood and tempo or generate ambient beds and one-shot effects locally with a pip install. The catch for game work is licensing: the code is MIT but every released checkpoint is CC BY-NC 4.0, so the models are for prototyping and placeholder audio, not for shipping in a paid game.
