生成混搭 (mashup)

- 把歌曲做混搭再创作。

  • 把歌曲做混搭再创作。
  • 引用源音轨:需恰好 2 个,用 task_ids(长度 2 的数组)+ 可选 audio_indexes 指定
  • 异步任务:提交返回 task_id,轮询 GET /v1/music/tasks/:task_id 获取结果
信息
**引用源音轨**:mashup 需要**恰好 2 个源音轨**——用 `task_ids`(长度为 2 的 task\_id 数组)指定,可选 `audio_indexes`(与之平行的数组,指定各任务取 `music[]` 第几首,1-based,默认都取 `1`)。
警告
`custom` 决定哪些字段生效:写在错误模式下的字段会被**静默忽略**(不报错)。`custom=true` 时 `prompt`(歌词)、`title`、`tags`、`negative_tags`、`auto_lyrics`、`style_weight`、`weirdness_constraint`、`audio_weight`、`persona_id` 生效,`gpt_description` 被忽略;`custom=false` 时只读 `gpt_description`(此时**必填**,缺了提交期直接返回 400)。`vocal_gender` 两种模式都生效。不传 `custom` 时后端按此顺序推断:有 `prompt` → `true`;无 `prompt` 但有 `gpt_description` → `false`;否则有 `tags`/`title` → `true`。

请求示例

Authorizations

Authorization string
所有接口均需要使用Bearer Token进行认证 获取 API Key: 访问 [API Key 管理页面](https://openveer.com) 获取您的 API Key 使用时在请求头中添加: ``` Authorization: Bearer YOUR_API_KEY ```

Body

model string
音频模型。当前传 `suno`(不传默认 `suno`)。
task_ids string[]
2 个源音轨所属任务的 `task_id` 数组(须**恰好 2 个**;数量不对提交期直接返回 `400`)。
audio_indexes integer[]
与 `task_ids` 平行的数组,指定各任务取结果 `music[]` 第几首(1-based,默认都取 `1`)。
instrumental boolean
是否纯器乐(`true`=无人声);不传默认 `false`(要人声)。
version string
生成版本:`v3.5` / `v4` / `v4.5` / `v4.5+` / `v4.5-all` / `v5` / `v5.5`,影响音质与计费;不传默认 `v5.5`,非法值提交期直接返回 `400`。
custom boolean
`true`=自定义模式(用 `prompt` 作歌词);`false`=灵感模式(用 `gpt_description`);不传时按内容推断(见上方 Warning)。
prompt string
歌词,`custom=true` 时生效(灵感模式下会被忽略)。
gpt_description string
灵感提示词,`custom=false` 时**必填**(缺了提交期直接 400、不扣费)。
title string
标题。**仅 `custom=true` 时生效**。
tags string
风格标签。**仅 `custom=true` 时生效**。
negative_tags string
要排除的风格标签。**仅 `custom=true` 时生效**。
auto_lyrics boolean
`true`=对输入歌词进行二次创作。**仅 `custom=true` 时生效**。
style_weight number
风格权重,`0.00`–`1.00`(越界提交期直接返回 `400`)。**仅 `custom=true` 时生效**。
weirdness_constraint number
创意权重,`0.00`–`1.00`(别名 `weirdness`)。**仅 `custom=true` 时生效**。
audio_weight number
音频权重,`0.00`–`1.00`。**仅 `custom=true` 时生效**。
vocal_gender string
人声性别:`Male` / `Female`。**两种模式都生效**。
persona_id string
Persona 风格 id。**仅 `custom=true` 时生效**。
注意
**获取结果**:本接口为异步任务。提交后拿到 `task_id`,按 3–5s 间隔轮询 `GET /v1/music/tasks/{task_id}`,直到 `status` 为 `completed` 或 `failed`(音乐生成通常 30–120s;生成中 `status` 为 `pending`,`progress` 排队 10 → 就绪 50 → 完成 100)。完成后从 `data.result.music[]` 取 `audio_url`。失败时 `data.error.message` 给出原因,且预扣额度自动退回。

Response

code integer
响应状态码
data array
返回数据数组 任务状态 * `submitted` - 已提交
task_id string
任务唯一标识符(用于轮询 `GET /v1/music/tasks/{task_id}` 获取结果)
