OFFICIAL PAGE: Moises
Moises is a web-based service for Deezer Research's Spleeter application. It allows you to upload a source file which will be separated into 2, 4, or 5 stems. An advanced setting returns the stems with their full frequency response. You can download the stems individually from the download links that are emailed to you, or as a zip file right from the website. A Web Mixer allows you to hear the separated stems in the context of a stereo mix with adjustable level and pan controls for each separated stem. The service is currently offered free of charge.
