Inputs (17)
| Name | Type | Default | Description |
|---|---|---|---|
| upload_url | STRING | https://storage.example.com/upload | The URL of the source audio file to cover. Required. Source audio (`upload_url`) is enough to generate. Ensure the uploaded audio does not exceed 8 minutes in length. |

If `lyrics` is present, `prompt` is not used as lyrics. - V6, V6_MINI, and V6_WILD: Maximum 5000 characters. - Not required. Source audio (`upload_url`) is enough to generate. - Do not pass this parameter when `instrumental` is `true`. |
| instrumental | BOOLEAN | true | Determines if the audio should be instrumental (no lyrics). - If `true`: generate instrumental music (no vocals). Do not pass `lyrics`, `prompt`, or `vocal_gender`. - If `false`: use `lyrics` as lyrics (fall back to `prompt` if `lyrics` is not provided). |

| vocal_genderopt | COMBO | m | Vocal gender preference for the singing voice. Optional. Use 'm' for male and 'f' for female.

| persona_idopt | STRING | persona_123 | Persona ID or Voice ID to apply to the generated music. Optional. Use this to apply a specific persona style to your music generation.

Integer range 0–4, default 1. - **`0`**: off (exact style) — fully off, strictly the same style - **`1`**: normal (balanced variety) — default, balances stability and diversity - **`2`**: high (distinct styles) — produces results with clearly different styles - **`3`**: extra (bold exploration) — higher variation, encourages bold exploration of different styles - **`4`**: max (unreasonably varied) — maximum diversity; results may differ in style very significantly |
| durationopt | INT | 2010–360 | Audio duration in seconds. Optional. Range 10–360, default 20. Valid when `model` is ~~V5_5~~ (Discontinued), V6, V6_MINI, or V6_WILD. |
