# StemStream

## Extract the "stems" (e.g. drums, vocals, bass) from any song on Spotify or Youtube into separate audio files

## Introduction

This is a Flask web app using the following resources:

- [Demucs ML model](https://github.com/facebookresearch/demucs): Demucs is an music source separation model that creates the stems
- [yt-dlp](https://github.com/yt-dlp/yt-dlp): Extracts the audio from the YouTube videos before passing them into demucs.
- [Spotify API](https://developer.spotify.com/documentation/web-api) & [Youtube Data API](https://developers.google.com/youtube/v3) for URL conversion
