Stem

A mixed-down audio file of one group of elements, like all the drums.

A stem is an audio file containing a mixed-down group of related elements from a song — for example, all the drums together, all the vocals, or all the instruments — bounced as a single track. Stems sit between the full mix and the individual raw tracks, and they are extremely useful: they let a mastering engineer make adjustments to broad groups, allow remixers and DJs to rework a song, and make live performance and collaboration easier. Sharing stems is a common way for producers to hand a project to someone else while keeping the major sections separate and controllable, without exposing every single track or revealing the original session files.

Our guides are written for beginners and reviewed by people who play, record and perform for a living, so the advice is what we'd tell a friend picking up the instrument, not specs copied off a box.
