# Digital Garden audio notices

Keep these notices when sharing the complete free browser extension. The extension license does not replace the following third-party licenses.

## Music and original synthesis

The eight music tracks are original Digital Garden compositions by Alicia, rendered by `authoring/music/compose.py`. The music uses CC0 sample libraries documented by this project: [VSCO 2 Community Edition](https://github.com/sgossner/VSCO-2-CE), [Versilian Community Sample Library](https://github.com/sgossner/VCSL), and [FreePats](https://freepats.zenvoid.org/). The original compositions are included under the Digital Garden free browser-extension permission. The CC0 samples retain their CC0 rights.

Procedural noise tracks are original project synthesis, not field recordings.
