Stability AI trains Stable Audio 2.0 on licensed AudioSparx music library

Stability AI said Stable Audio 2.0 was exclusively trained on a licensed dataset from the AudioSparx music library, more than 800,000 files including music, sound effects and single-instrument stems. AudioSparx artists were given the option to opt out. Financial terms were not disclosed.

April 3, 2024 Stability AI announced that Stable Audio 2.0 was exclusively trained on a licensed dataset from the AudioSparx music library.1 Financial terms were not disclosed.

Terms of the deal

According to Stability AI, the model was trained on more than 800,000 AudioSparx files, including music, sound effects and single-instrument stems, along with matching text metadata.1 All AudioSparx artists were given the option to opt out of training the model, and Stability AI said the approach ensures fair compensation for creators.1 The announcement gave no payment amounts or contract length.

Background

Stability AI's page that carries this statement is dated April 3 and does not show the year in the text retrieved, which matches the release of Stable Audio 2.0. An earlier version of Stable Audio was also reported to use AudioSparx data.

What it means for data sellers

The case shows a catalogue owner licensing a full library for model training while giving its artists an opt-out. Sellers with large music or sound libraries can use clean licensing and metadata as selling points, though this deal published no price.
