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 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!

Using StemRoller couldn't be easier - just head to the StemRoller website or the releases page and download the latest version! That bundle includes everything you need to split stems. If, however, you want to get involved in StemRoller development, read on...

git clone https://github.com/stemrollerapp/stemroller.git
cd stemroller

Install ffmpeg globally using your preferred package manager, and install demucs globally with pip.

Linux is not yet officially supported, but thanks to some kind contributors, we now have experimental Linux support if you're willing to run StemRoller from source. You can, of course, also run in development mode on Linux.
