Usage Guide

  • Separate a platform‑generated mix into vocal, instrumental, and individual instrument components.
  • Two processing modes are available:
    • separate_vocal — 2‑stem split
    • split_stem   — up to 12‑stem split
  • Ideal for karaoke creation, remixes, sample extraction, or detailed post‑production.
  • Best results on professionally mixed AI tracks with clear vocal and instrumental layers.
  • Billing notice: Each call consumes credits; re‑calling the same track is charged again (no server‑side caching).
  • Pricing: Check current per‑call credit costs at https://kie.ai/billing.

Developer Notes

  • All returned audio‑file URLs remain accessible for 14 days.
  • Separation quality depends on the complexity and mixing of the original track.
  • separate_vocal returns 2 stems — vocals + instrumental.
  • split_stem returns up to 12 independent stems — vocals, backing vocals, drums, bass, guitar, keyboard, strings, brass, woodwinds, percussion, synth, FX/other.
  • Billing: Every request is charged. Re‑submitting the same track triggers a new credit deduction (no server‑side caching).
