Generate music and sound effects from text prompts.
Audio & Voice
Stable Audio is Stability AI's music and sound-effects generator — the third leg of the Stability stack alongside Stable Diffusion for images and the various Stable Video releases for motion. Launched in September 2023 and rebuilt around the Stable Audio 2.0 architecture in 2024, it took a different route from Suno and Udio: instead of chasing full-song lyric-and-vocal generation, Stable Audio doubled down on high-quality instrumental music, sound effects, sample-length loops, and audio-to-audio transformation. As of 2026 it is the AI music tool producers actually reach for when they need a stem, a loop, a sound effect, or an instrumental bed — not when they need a pop song with vocals. It is also the only major AI music tool with a genuinely open path — Stable Audio Open is a permissively-licensed open-weights model available to run locally, which matters if you care about privacy, on-prem deployment, or building on top of the model directly.
What Stable Audio actually does, cleanly stated, is turn a text prompt or a reference audio clip into instrumental music or a sound effect, up to about 3 minutes long, at up to 44.1 kHz stereo quality. You type a prompt ("driving synthwave bass line, 120 BPM, arpeggiated pad, no drums"), pick a duration, and Stable Audio generates a clip that behaves like a real music production element rather than a full song. You can also upload a reference audio clip and prompt the model to transform, extend, or generate variations of it — the audio-to-audio workflow that makes Stable Audio a genuine tool inside a DAW-based workflow rather than a novelty end-to-end song generator.
The one-line positioning: Stable Audio is the tool you use when you need instrumental music, sound effects, or loops — for a game, a video, a beat, a soundscape, or a piece you are producing yourself — and full-song vocal generators are the wrong shape for the job. It is not going to sing you a chorus. It will hand you a bassline, a pad, a percussion loop, or a 90-second cinematic underscore that lands cleanly in Ableton or Logic and cuts against picture without a vocal fighting the dialogue.
Stable Audio's product is built around the instrumental and audio-effect workflow. The features that earn the subscription are the 2.0 model, audio-to-audio, sound-effect generation, and the open-weights option.
Text-to-audio generation (Stable Audio 2.0 and Stable Audio Open). The flagship models. Prompt for instrumental music, ambient beds, cinematic underscore, or sound effects; get up to 3 minutes of stereo audio at 44.1 kHz. The 2.0 model produces coherent musical structure across the full duration — intro, development, resolution — rather than the loop-and-fade behavior of earlier releases.
Audio-to-audio. Upload a reference clip (your hummed melody, a rough demo, an existing loop, a field recording) and prompt Stable Audio to transform, extend, or generate a variation. This is the workflow producers actually use — it turns Stable Audio into a collaborator, not a black-box generator.
Sound-effect generation. Prompt for specific sounds — "heavy wooden door slamming with reverb tail," "sci-fi laser with metallic ricochet," "rainstorm on a metal roof, distant thunder." The output is dramatically better than the free sound-effect libraries that indie developers used to comb through. Popular with game developers, video producers, and podcasters.
Duration control up to 3 minutes. Set the target length in seconds. The model structures the composition to fit — a 15-second clip has a different arc than a 90-second cinematic bed.
Multi-track prompt weighting. Type prompts that layer instructions ("cinematic strings, subtle piano melody, no drums, dark and tense") and the model treats each element with weight. Not as precise as a MIDI editor, but tighter than most competitors' single-prompt inputs.
Stable Audio Open (open-weights). The permissively-licensed open model available on Hugging Face. You can run it locally, fine-tune it, and build on top of it. This is the only major AI music model that ships as open weights — which matters if you care about privacy, on-prem, or building a product on the model itself.
API access. The Stability AI platform exposes Stable Audio via the same API surface as Stable Diffusion and other Stability models. Programmatic generation for developers building music into apps, games, and content pipelines.
Commercial rights on paid tiers. Music and sound effects generated on paid plans come with commercial rights — usable in videos, games, ads, and paid content. Free tier is personal use only with attribution requirements.
Stable Audio is freemium and priced in monthly credit tiers. Pricing shifts periodically and Stability AI runs bundled offers across their broader model catalog; check the current site before committing.
| Plan | Monthly | Generations / month | Duration cap | Commercial |
|---|---|---|---|---|
| Free | $0 | ~20 tracks | 45 seconds | Personal only |
| Standard | ~$12 | 500 credits (~100 tracks) | 3 minutes | Yes |
| Pro | ~$30 | 1,500 credits (~300 tracks) | 3 minutes | Yes + API access |
| Enterprise / API | Custom | Custom | 3 minutes | Custom |
| Stable Audio Open | Free (open weights) | Unlimited (self-hosted) | Model-dependent | Per model license |
Free at ~20 tracks per month with a 45-second duration cap is a real trial — enough to test whether the model fits your workflow, not enough to build with. Standard at ~$12/month is the tier hobby producers, indie game developers, and content creators sit on — 100 full-length tracks per month covers most creative use. Pro at ~$30/month unlocks API access and higher volume for teams and semi-pro producers.
Stable Audio Open is the wildcard. The open-weights model is downloadable and self-hostable at no cost. Output quality is behind the 2.0 hosted model, but the freedom to run locally, fine-tune, and build derivative products is a real advantage for teams with the engineering to use it.
The honest read: for casual instrumental generation, Stable Audio Standard at ~$12/month is priced between Suno Pro at $8 and Udio Standard at $8 on one side, and AIVA Pro at ~33 EUR on the other. You pay slightly more than Suno/Udio for a tool that does a narrower job better — instrumental and sound-effect generation without the pop-song artifacts.
Pros
Cons
Producers generating stems, loops, and samples for use in a DAW. Prompt for a bassline, a pad, a percussion loop, or a chord progression and drop the result into Ableton, Logic, or FL Studio. Stable Audio as a limitless sample pack.
Indie game developers scoring on a solo-dev budget. Instrumental cues, ambient beds, and sound effects for characters, environments, and UI. The sound-effect generator alone is worth the subscription for game developers who used to buy sound packs at $50 each.
Video creators needing instrumental underscore. For channels and content where the music is background and vocals would fight the dialogue — documentary, tutorial, tech review, science communication — Stable Audio is often the right AI music tool.
Podcasters producing instrumental intros, interstitials, and ad-break beds. Music underneath a monologue needs to not have its own vocals. Stable Audio's instrumental focus is the whole point.
Ambient and electronic producers. The model is particularly strong on ambient, electronic, cinematic, and experimental genres — the styles Stable Audio's training and output distribution favor.
Developers and researchers building on the open model. Stable Audio Open's open-weights release makes it the only serious AI music model you can fine-tune, embed in a product, and run privately without a hosted API contract.
Producers who tried Suno and Udio and want cleaner instrumentals. The absence of vocals is a feature, not a bug — you get a full production element without a phantom vocal ghost to remove.
Stable Audio's competition splits into three lanes: full-song generators that do a different job, other instrumental-focused tools, and sample libraries.
Suno — the full-song lyric-and-vocal generator at $8/month. Better for pop, rock, hip-hop, and any genre where vocals are the point. Worse for pure instrumental production, sound effects, and audio-to-audio workflow.
Udio — the other full-song generator, at parity with Suno on pricing. Higher audio fidelity than Suno on many genres, extend workflow, stems on Pro. Same limitation vs Stable Audio: focused on full songs with vocals, weaker at pure instrumental sample and loop generation.
AIVA — orchestral and film-score focused AI composer with MIDI export. Better than Stable Audio on classical, cinematic, and orchestral music with note-level editing. Narrower stylistic range but deeper compositional structure.
Soundraw and Mubert — parameter-driven stock-music alternatives. Pick mood, genre, length; the tool assembles a track from a sample library. Cheaper feel, weaker on audio-to-audio, no sound-effect generation.
ElevenLabs Sound Effects — ElevenLabs's sound-effect generator bundled with its higher voice tiers. Not category-leading, but if you already pay for ElevenLabs for voice, it is free-with-your-subscription sound effects.
Splice and Loopcloud — traditional sample libraries. Human-produced loops and stems, subscription pricing, no AI generation. Still the safe choice for commercial work that needs unambiguous licensing.
Epidemic Sound and Artlist — the human-composed stock music incumbents. Higher quality per track, higher price, no per-prompt customization. Still the safe choice for larger channels and brand work.
Open-weights alternatives on Hugging Face — Meta's MusicGen and Google's MusicLM derivatives are the direct competitors to Stable Audio Open. MusicGen is the most-used alternative for developers building on top of an AI music model.
Try the free tier at stableaudio.com. ~20 generations per month at up to 45 seconds is enough to test the model on the styles and prompts you actually need. Start with instrumental and sound-effect prompts, not full-song prompts.
Compare against your existing sample library. Prompt for a loop or sample you would otherwise buy from Splice — a bassline, a drum break, a pad. If the AI-generated version lands in your DAW and mixes cleanly, Stable Audio is a real alternative.
Test the audio-to-audio workflow. Upload a rough loop, hummed melody, or reference clip and prompt Stable Audio to transform or extend it. This is the workflow that separates Stable Audio from prompt-only generators.
Try the sound-effect generator on a real production need. Game developers, podcasters, and video producers should specifically test this — it is arguably the strongest single use case for the tool.
Upgrade to Standard if the tool sticks (~$12/month). 100 tracks per month plus full commercial rights covers most instrumental production work. Pro at ~$30/month is for teams and API users.
If you have engineering budget, try Stable Audio Open. The open-weights model runs locally and is embeddable in your own products. Quality is behind the hosted 2.0 model but the deployment freedom is unique in AI music.
Is Stable Audio better than Suno or Udio? For instrumental music, sound effects, and audio-to-audio workflows, yes — the model is purpose-built for that job. For full songs with vocals and lyrics, no — Stable Audio does not sing. Pick based on whether you need vocals.
Does Stable Audio generate vocals? No. Stable Audio is instrumental-only. For vocal tracks, use Suno, Udio, or ElevenLabs for voice-first generation.
Can I use Stable Audio music commercially? Yes, on Standard and Pro. Free tier is personal use only. Read the current terms before high-stakes commercial usage — the AI music copyright landscape is still evolving and Stability AI is party to multiple ongoing lawsuits.
What is Stable Audio Open? An open-weights version of Stable Audio, released under a permissive license. You can download the model, run it locally, and fine-tune it. Quality is meaningfully behind the hosted 2.0 model, but you own the deployment.
What sample rate does Stable Audio output? 44.1 kHz stereo on the hosted 2.0 model. This is CD-quality and lands cleanly in a DAW without upsampling.
How long can generated tracks be? Up to 3 minutes on Standard and Pro. 45 seconds on Free. For longer tracks, generate multiple sections and edit together in a DAW.
Does Stable Audio have an API? Yes, on Pro and Enterprise. Programmatic generation via the Stability AI platform. Documentation is developer-grade.
Stable Audio Standard at ~$12/month is the AI music tool for producers, indie game developers, and video creators who need instrumental music, sound effects, and audio-to-audio transformation — as distinct from the full-song vocal generators that dominate AI music headlines. The 2.0 model produces coherent musical structure at production sample rates, the sound-effect generator is category-leading, and the audio-to-audio workflow turns the tool into a real collaborator inside a DAW. For anyone whose job involves loops, stems, samples, sound effects, or instrumental beds, Stable Audio earns its subscription faster than any full-song generator.
Where Stable Audio stops being the right answer: full songs with vocals and lyrics (Suno and Udio do that job at $8/month); orchestral and cinematic scoring with MIDI editing (AIVA is the tool); and creators who want a polished consumer product with a big preset library and no prompt-engineering learning curve. But for producers who want a serious instrumental and sound-effect tool with an open-weights escape hatch, Stable Audio is the tool.
The honest recommendation: try the free tier at stableaudio.com with a real production need — a loop for a track, a sound effect for a game, a cinematic bed for a video. If the output lands in your DAW and mixes cleanly, subscribe at Standard for ~$12/month. If you also need vocal songs, add Suno at $8/month annual — the two tools are complementary, not substitutes.
