About Stable Audio
What Is Stable Audio
Stable Audio is the AI audio product line from Stability AI, the company behind Stable Diffusion. You describe what you want to hear, such as the genre, instruments, mood, and tempo, and the model writes a finished track or a sound effect. It handles both background music and standalone sounds, from cinematic scores to a single car passing by.
The tool is built for speed and length control. Earlier versions capped tracks at a few minutes, and the Stable Audio 3.0 family, released in May 2026, pushes full compositions up to around six minutes at CD-quality 44.1 kHz stereo. Stability AI says the model is trained on fully licensed data, which matters if you plan to use the output in commercial work.
The main limits are worth knowing up front. Free and low-cost plans come with monthly generation limits and shorter outputs, and the most capable Large model is not open-weight. It's offered through the API and paid hosting instead. Stable Audio also generates instrumental audio, not sung vocals, so songwriting with lyrics is out of scope.

Key features
Text-to-Audio Generation
The core feature turns a written prompt into audio. For anyone searching for text to music, you describe genre, instruments, mood, and tempo, and Stable Audio produces a track that matches. It covers AI audio generation for both full musical compositions and standalone sounds, so one tool covers scoring and sound design.
Variable-Length Tracks Up to Six Minutes
Stable Audio controls how long the output runs, which avoids the chopped-off endings that older audio diffusion models produced. The Stable Audio 3.0 family generates full songs with intro, verse, and outro structure up to around six minutes and 20 seconds, more than double what version 2.0 could manage.
Audio-to-Audio and Inpainting
You can upload a clip and describe how to change it. The model reworks the style or extends a section, and inpainting lets you modify a specific segment while keeping the rest intact. This turns generation into a starting point rather than a final step.
Sound Effects Generation
Beyond music, Stable Audio builds standalone sound effects. Typing a description yields effects such as footsteps, crowd noise, or a passing car, which is useful for video, games, and podcasts that need specific audio without a recording session.
Open-Weight Small and Medium Models
Stability AI released the weights for the Small and Medium models in the 3.0 family, so developers can download and modify them. The smaller models are optimized to run on devices, which supports local generation without cloud calls.
API and Enterprise Deployment
The largest model is available through the Stability AI API and paid hosting, which suits teams that want managed infrastructure and easy integration into their own apps. An enterprise license adds legal indemnification for commercial use, and custom model tuning is offered on request.
