Stem
A grouped audio track containing multiple individual elements, used for mixing, mastering, and licensing purposes.
Definition
Stems are grouped audio exports—drums, bass, vocals, synths—that sit between full mixes and individual tracks. They enable remix flexibility, live performance manipulation, and sync licensing adaptability without accessing raw session files.
Standard stem exports typically include: drums/percussion, bass, vocals, melodic elements, and effects. Sync licensors often request stems to adjust mixes for their visual context.
Why It Matters
Stems enable music flexibility after production. DJs remix with stems. Sync supervisors adjust mixes for scenes. Live performers trigger stem elements. Without stems, these applications are impossible or require full remix.
Providing stems can increase licensing value. Licensees pay premiums for flexibility to mute vocals, isolate beats, or create alternate mixes—capabilities stems provide.
Examples in Practice
A sync supervisor licenses a track but needs the vocals lower for dialogue. Stems allow easy adjustment without contacting the original producer for a custom mix.
A DJ creates a live remix using stem separation, triggering drum patterns independently while manipulating the melodic elements in real-time.
