# StemRoller

StemRoller is the first free app which enables you to separate vocal and instrumental stems from any song with a single click! StemRoller uses Facebook's state-of-the-art [Demucs](https://github.com/facebookresearch/demucs) algorithm for demixing songs and integrates search results from YouTube.

Simply type the name/artist of any song into the search bar and click the **Split** button that appears in the results! You'll need to wait several minutes for splitting to complete. Once stems have been extracted, you'll see an **Open** button next to the song - click that to access your stems!

_We also have a [Discord server](https://www.stemroller.com/chat) with update announcements and support_.
