Stability AI: Stable Audio 2.5

Stable Audio 2.5 is Stability AI's text-to-audio model for music and sound effects. It can turn descriptions of instruments, atmosphere and musical development into evolving audio, with seed and requested-duration controls. The official example develops a quiet piano figure into a larger orchestral moment, illustrating how a prompt can express both the starting material and the intended dynamic arc. This makes it useful for work that combines composition and scene-oriented sound design. Use cases: cinematic underscore, orchestral sketches, evolving musical beds and sound-effect concepts.
