Stable Audio is Stability AI's text-to-audio tool for music and sound effects, with the 2.5 model producing structured, multi-part tracks in seconds and supporting inpainting. It's commercially cleared, with web subscriptions and a cheap pay-per-use API. Strong for instrumental beds and SFX; Suno and Udio still lead on full vocal songs.

Creators and developers needing royalty-cleared background music and sound effects, via app or API.
Pros
- Fast, structured music and sound-effect generation
- Commercially cleared output
- Audio inpainting to extend your own clips
- Cheap pay-per-use API alongside subscriptions
Cons
- Weaker on full vocal songs than Suno/Udio

How it compares
Versus Suno and Udio it's aimed more at instrumental beds, SFX and API use than radio-style songs with vocals.
Full review
Stable Audio is Stability AI's text-to-audio tool for music and sound effects. The 2.5 model generates structured, multi-part tracks — intro, development, outro — up to around three minutes in a couple of seconds on a GPU, follows mood and genre prompts well, and supports inpainting so you can feed in your own clip and have it extend the rest.
Output is commercially cleared, and you can use it through web subscriptions or a pay-per-use API (about $0.20 for a long track) on Stability's platform and partners like fal and Replicate. It's strongest for instrumental beds, ambience and SFX; for full songs with vocals, Suno and Udio still lead. The cheap API makes it practical for developers adding audio to apps on a budget.
