What is Stable Audio?
Stable Audio is Stability AI's generative audio tool: it creates instrumental tracks and sound effects from a text description. Version 3.0 (May 2026) reaches up to 6 minutes 20 seconds per composition, and its Stable Audio Open models are open-weight, so you can run them free on your own machine if you have a GPU. It is trained on licensed music, which makes it safe for commercial use.
Pros
- Open-weight models: free and unlimited if you run them locally
- Trained on licensed music: safe for commercial use
- Generates sound effects too, not just music
- Long compositions (up to 6 min 20 s on the larger models)
Cons
- Does not generate vocals or lyrics, only instrumentals and effects
- The free plan is limited to 24 one-off credits
- English-only interface
What Stable Audio is like in practice
Where it stands out
It stands out at sound effects and short production-quality tracks: you can ask for a specific sound and it delivers it clean, something that usually means digging through libraries. It is built to fit a professional audio workflow, with control over exact duration and output quality suitable for editing.
Where it falls short
On full songs with structure and vocals it trails the specialists: its ground is short pieces and sound, not long-form composition. And like the rest of the generation catalogue, licensing varies by plan, so commercial use must be confirmed in the current terms rather than assumed.
How its pricing works
There are free monthly generations for testing and paid plans by volume. For audiovisual production, the useful calculation is against what a sound effects library costs: if you need very specific sounds you cannot find, generating is cheaper; if you want generic background music, the library wins.
Is Stable Audio right for you?
Yes, if…
You need music or sound effects with the peace of mind of being able to use them commercially: it trains on licensed music. And its open models run free on your machine if you have a GPU.
No, if…
You want songs with vocals: it only generates instrumentals and effects. Suno, Udio or Riffusion are for that. And its 24 free credits are one-off.
