- 对已生成的歌曲做母带处理,异步任务
- 提升响度、清晰度与整体质感

认证
All endpoints authenticate with a Bearer token.
Get an API key: open the console and create one.
Add it to the request header:
Authorization: Bearer YOUR_OAIRoute_KEY引用源音轨
指定源音轨所在那次任务的 task_id。缺少或无法定位源音轨时,提交阶段即返回 400。
选择源任务结果 data.result.music[] 中的第几首,默认 1。
一次生成通常返回 2 首,索引为 1 与 2。这个参数就是定位源音轨的依据,不需要额外 id。
The task_id of the task holding the source track. When it's missing or the source can't be located, submission returns a 400.
Which track in the source task's data.result.music[], default 1.
A single generation usually returns 2, at indexes 1 and 2. This parameter is what locates the source track; no extra id is needed.
请求参数
音频模型,默认 suno,当前仅 suno。
改编强度,取值 subtle、normal、high。
subtle只做轻微的响度与均衡调整normal常规母带处理high改动明显,可能改变音色倾向
输出音频格式,取值 mp3、m4a、wav。

Output audio format: mp3, m4a, or wav.
不支持的参数
version、custom_model_id、max_mode、variety、目标时长字段都不支持。这个端点没有版本维度。
version, custom_model_id, max_mode, variety, and target duration fields are all unsupported. This endpoint has no version dimension.
响应
响应状态码。
提交成功时为 submitted。
任务唯一标识,用于轮询。
轮询用 GET /v1/music/tasks/{task_id},间隔 3 到 5 秒,典型耗时 30 到 120 秒。progress 是 0 到 100 的整数,不保证按固定节点变化。完成后从 data.result.music[].audio_url 取优化后的音频地址。失败时 data.error.message 给出原因,同时自动退回预扣额度。
The response status code.
submitted on successful submission.
The unique task identifier, for polling.
Poll with GET /v1/music/tasks/{task_id} every 3 to 5 seconds; typical duration is 30 to 120 seconds. progress is an integer from 0 to 100 that isn't guaranteed to change on fixed steps. On completion, take the mastered audio URL from data.result.music[].audio_url. On failure, data.error.message gives the reason and the held balance is refunded automatically.
强度怎么选
| 强度 | 适用 | 风险 |
|---|---|---|
subtle | 已经很满意,只想统一响度 | 几乎无风险 |
normal | 默认选择,日常够用 | 轻微改变音色 |
high | 原始音频偏闷或偏薄 | 可能把好听的细节也改掉 |
建议先用 normal 听一版。觉得变化不够再往 high 走,觉得改味了退回 subtle。
母带处理会重新编码,这是不可逆的。原始文件要留着,不要用母带版覆盖原件。反复对同一首做母带,画质会累积下降。
| Strength | Best for | Risk |
|---|---|---|
subtle | Already happy, just evening out loudness | Almost none |
normal | The default, enough for everyday use | Slight tonal change |
high | The source sounds dull or thin | May also erase good detail |
Start with a normal listen. If the change isn't enough, move toward high; if it alters the character, retreat to subtle.
Mastering re-encodes and is irreversible. Keep the original file; don't overwrite it with the mastered version. Mastering the same song repeatedly accumulates quality loss.

使用示例
提交一个任务并拿到 task_id:
提交成功只表示任务已受理。真正的产物要拿返回的 task_id 去任务查询接口轮询,status 变成 completed 之后才有结果。
Submit a task and get a task_id:
A successful submission only means the task was accepted. To get the actual output, poll the task query endpoint with the returned task_id; results appear only after status becomes completed.
