- What ends up in the 'other' stem?
- Everything that isn't vocals, drums, or bass: guitars, pianos, synths, strings, brass. It's the catch-all for melodic and harmonic content — useful as a backing bed or for sampling chord progressions.
- Can I rebalance a song with the stems (turn vocals down, drums up)?
- Yes — that's the classic use. Drop all four WAVs into any DAW (or even a phone video editor), and they're already time-aligned. Mute, rebalance, or effect each stem independently, then bounce your new mix.
- How is this different from the vocal remover?
- The vocal remover gives you two stems (vocals + instrumental). This tool splits the instrumental further into drums, bass, and other — four stems total from the same upload. If you only need a karaoke track, the vocal remover is faster; if you need the parts, use this.
- Is there a length limit?
- Free tier processes up to 60 seconds per track — enough to evaluate quality. Lite and Pro plans remove the cap for full songs and DJ sets.
