The Stem Creator first imports four elements of a track, each previously prepared as separate audio files in a DAW or wave editor, along with a stereo master of the whole track. Once imported, metadata like stem name, album title, and stem color can be edited. Then master compression and limiting can be applied to all stems for balanced playback. After compression and limiting is adjusted, the Stem Creator exports and packs the stems into a single stem.mp4 file.
Take a look at this quick tutorial video for a step-by-step guide on creating Stem files.
