About suno_stem

Suno 音轨分离接口,用于提取人声或乐器等分轨。

Use cases and prompting

Starting points for evaluation; supported inputs and options are listed in API access.

Use cases to explore

  • Explore background music directions for videos, podcasts and games.
  • Prototype an arrangement and mood before producing a final soundtrack.

Practical tips

Describe genre, mood, instruments and progression. Specify vocals only if supported, and verify duration controls in the API documentation.

Example prompt

Instrumental background music for a calm morning scene: soft piano, light strings, a gentle pulse and a gradual build, without vocals.

array—Up to 4 strings that stop generation
seed
integer—Deterministic sampling seed (best-effort)
n
integer
=1>= 1
Number of completions to generate
stream

Replace <YOUR_API_KEY> with the API key from your token settings.

Authentication

All requests must include Authorization: Bearer <TOKEN> header. Anthropic-formatted endpoints accept the x-api-key header instead.

Generate tokens from the Tokens page; you can scope them to specific models, groups, IPs, and rate-limits.
