Stable Audio
Stable Audio Open from Stability AI is an open-source text-to-audio model with ~1.2B parameters, capable of generating up to 47 seconds of stereo audio at 44.1 kHz. Built on a latent diffusion transformer architecture with T5-based text conditioning, it excels at drum beats, instrument riffs, ambient sounds, and foley recordings. Trained exclusively on Creative Commons-licensed data (7,300 hours), it is ideal for sound design and music production workflows where royalty-free audio is required.

FAQ
How much does Stable Audio cost? Is it free?+
How does Layer's pricing work?+
There are no seat fees, feature gates, or plans on Layer. Instead, our platform uses a consumption based system with Creative Units (CUs) with a flexible monthly subscription. Every generation on Layer (image, video, 3D, or audio) consumes a Creative Unit, and you only pay for what you create.
