Stable Audio 3 FAQ
What is Stable Audio 3?
Stable Audio 3 is a family of open-weight AI audio generation models from Stability AI, released in May 2026. It generates music, sound effects, and ambient audio from text prompts, and supports audio-to-audio editing and inpainting. This site lets you use Stable Audio 3 online — no install, no GPU, right in your browser.
Is Stable Audio 3 free to use online?
Yes — this page is free to try and does not add a local paywall, credit card step, or app account requirement. Generation availability can still depend on the hosted demo queue and current model provider limits.
Do I need a GPU to run Stable Audio 3 online?
No. Stable Audio 3 runs in the cloud here, so you only need a browser and an internet connection. No downloads, no GPU, no local setup.
Do I need an account to use Stable Audio 3?
No. You can start using Stable Audio 3 immediately — no registration, no login, no email required. Just open the page and generate.
What audio quality does Stable Audio 3 output?
Stable Audio 3 generates audio in 44.1 kHz stereo, and you can download your results as WAV files — lossless, ready to drop into any DAW, video editor, or game engine. Output quality depends on the model variant, prompt specificity, and duration settings.
How long can Stable Audio 3 generated audio be?
It depends on the model. Stable Audio 3 Medium generates up to approximately 6 minutes 20 seconds. Small Music and Small SFX generate up to about 2 minutes. You can choose any duration up to the model limit in the generator.
Can I use Stable Audio 3 outputs commercially?
Stability AI says Stable Audio 3 outputs can be distributed and commercialized under the Stability AI Community License. Organizations above the current revenue threshold should use the Enterprise License, so check the latest Stability AI terms before production use.
Can Stable Audio 3 generate vocals, speech, or lyrics?
No. Stable Audio 3 is designed for instrumental music, sound effects, and ambient audio. It does not generate vocals, speech, singing, or lyrics. For voice or speech, you need a text-to-speech or voice AI tool instead.
What's the difference between Stable Audio 3 Medium, Small Music, and Small SFX?
Medium handles full song composition with the strongest musicality and the longest duration (up to ~6 min) — best for complete tracks. Small Music covers shorter loops and sketches (up to ~2 min) and can run on CPU. Small SFX is optimized for sound effects: impacts, footsteps, ambience, and UI sounds — fast generation, short outputs, ideal for game audio and quick one-shots.
How do I write a good prompt for Stable Audio 3?
Describe genre first, then instruments, mood, tempo, and key (if relevant). A strong Stable Audio 3 prompt example: Cinematic orchestral score, sweeping strings and brass, epic and emotional, 120 BPM in D minor. Avoid vague descriptions like "nice music" — the more specific your prompt, the more intentional the output.
How does Stable Audio 3 compare to Suno or Udio?
Stable Audio 3 and Suno/Udio serve different purposes. Suno and Udio focus on generating complete songs with vocals and lyrics — they are AI song generators. Stable Audio 3 focuses on instrumental music, sound effects, ambient audio, and audio editing (inpainting, audio-to-audio). If you need instrumental beds for video, game audio sketches, or sound effects, Stable Audio 3 is the better fit.
Are my Stable Audio 3 uploads and prompts private?
Uploaded audio files and prompts are processed only to generate your requested output and are not used to train models. Review our Privacy Policy for full details on storage and retention.
