Short answer
A stem is an isolated layer of a song, such as just the vocals, just the drums or just the instruments. Stems let you remix, make karaoke versions, or balance a mix. Autunes, powered by the Zori models, includes built-in stem separation so you can split a track into its parts without extra software.
A finished song is a mix of layers. A stem is one of those layers pulled out on its own, so you can work with the vocals or instruments separately.
Stems let you make karaoke tracks, remixes, or rebalance a mix. Autunes has stem separation built in, so you don't need extra tools.
