Stemroller
StemRoller separates songs into vocal, drum, bass, and other instrumental tracks using the Demucs algorithm, with YouTube search integration.
About Stemroller
StemRoller is an application that separates a song into vocal, drum, bass, and other instrumental stems. It uses Facebook's Demucs algorithm for the separation and integrates YouTube search results. To use it, a person types the name or artist of a song into the search bar and clicks the Split button on a result. Splitting takes several minutes. Once it finishes, an Open button next to the song gives access to the stems.
The project's README describes a downloadable release bundle that includes everything needed to split stems. Developers can also set up the project from source. Linux is not officially supported. That setup requires installing ffmpeg globally, and installing demucs and yt-dlp with pip. Pricing is not known.
