Moises Mobile App
Moises is a web-based service for Deezer Research's Spleeter application. The Moises Mobile App allows you to easily harness the power of Moises on your iOS or Android device. It allows you to upload a source file which will be separated into 2, 4, or up to 5 stems. An advanced setting returns the stems with their full frequency response. The separated stems can be downloaded as MP3 files or as uncompressed WAV files. Additional features include the ability to adjust the pitch and tempo of the song. The service is currently offered with both free and premium options.
