Stable Audio

Stable Audio is Stability AI’s music and sound generation platform, creating commercial-ready tracks, stems, and sound effects from text prompts.

Overview

Stable Audio applies Stability AI’s diffusion approach to audio, generating full musical compositions, isolated instruments, and sound effects from text descriptions. Trained on a licensed catalog from AudioSparx, it avoids the legal gray areas of scraped-music models, and paid plans include commercial usage rights. Version 2.0 extended generation length and added audio-to-audio prompting.

The web player makes it easy to iterate on prompts, adjust duration, and export high-quality stereo files. Because the model can produce individual instrument stems and effects, it serves both musicians sketching ideas and video creators who need on-demand royalty-free sound.

Sound designers value the stem and effects modes as much as full tracks: generating an isolated bass line, a riser, or an ambient bed lets editors layer audio precisely instead of fighting with full mixes. Duration control makes clips fit ad slots and scene lengths without trimming artifacts.
