Stable Audio

Stable Audio is Stability AI's text-to-audio platform for generating music and sound effects from prompts, with strong control over duration and structure plus audio-to-audio restyling. It suits creators who need production-ready beds and SFX rather than vocal songs. A free non-commercial tier plus paid Pro/Studio/Max plans and an API cover hobbyists through developers, with commercial licensing on paid tiers.

Stable Audio generates original music and sound effects from natural-language prompts, and can also transform existing audio (audio-to-audio) to restyle or extend it. A defining feature is fine-grained timing control: you can specify duration and structure, which makes it well suited to production tasks like scoring a clip to an exact length or generating loopable beds and one-shot sound effects. The hosted app at stableaudio.com runs Stability AI's current music model (Stable Audio 2.5 as of late 2025), while the broader Stable Audio family has continued to evolve, including open-weight-oriented releases aimed at developers that push toward longer compositions. This dual track, a consumer/creator web app plus research and developer models, reflects Stability AI's open-model heritage. Commercially, Stable Audio uses a freemium structure. The free tier is intended for personal, non-commercial exploration with limited monthly generations, while paid tiers (reported around $11.99/month for the entry Pro plan and higher Studio/Max options) add commercial licensing, more generations and higher-quality exports. Prospective users should read the licensing and distribution terms carefully, as commercial rights and streaming-distribution rules are a frequent point of nuance.
