There’s been widespread industry focus lately on audio generative AI models, with OpenAI this week releasing the latest updates of its own model, Voice Engine. Now joining the trend is Stability AI, which has revealed its own most advanced audio model.

On Wednesday, Stability AI — the open-source AI company best known for its Stable Diffusion model — unveiled Stable Audio 2. This new model offers significant upgrades over its predecessor — Stable Audio 1.0 — beyond text-to-audio capabilities. 

Stable Audio 2 has audio-to-audio capabilities, which enable users to upload audio samples and create a wide array of sounds using natural language prompts. With style transfer, you can modify generated or uploaded audio to align with a specific style and tone.

To protect creative integrity and artists’ rights, the uploads have to be free of copyrighted material. The company uses content recognition technology from Audible Magic to prevent such infringement and ensure users are compliant. 

To further protect artists, Stable Audio 1.0 and Stable Audio 2.0 were trained on data from AudioSparx, which consists of more than 800,000 audio files, and whose artists were given the option to opt out of the Stable Audio model training. 

The new model can also produce tracks up to three minutes long at 44.1 kHz stereo, a significant upgrade over Stable Audio which could only produce tracks up to 45 seconds long. The three-minute generation includes all the elements needed in a song such as melodies, backing track, sound effects, and more.
