About Suno Stem

把整首歌拆开来处理

一首歌曲的混音中,人声与乐器已经叠在一起。Suno 分轨可从已有音乐中提取不同部分,让你单独调整人声响度、减轻鼓点、替换伴奏,或为翻唱练习准备素材。它适合需要继续编辑成品音频的创作者、剪辑师和音乐制作人。

提交前先确定用途。只想得到人声和伴奏时,选择相应分离类型即可;若想重新安排编曲,则需要查看接口是否提供鼓、贝斯等更细的乐器分轨。不同任务可选的分轨方式可能不同,应按照实际支持项选择,避免预设一定会返回固定数量的轨道。

分离后就是原始录音吗?

分轨是在混合音频中估计并提取声音,不会恢复录音棚里的原始工程。复杂混音、重叠频段和混响可能留下串音或处理痕迹。试听时特别留意人声尾音、鼓点瞬态和乐器重叠段,再决定是否适合独立使用。

怎样放回音频工程?

下载需要的轨道后,保持它们的起始位置一致,再分别调整音量与效果。不要随意裁去某一轨前面的空白,否则会破坏对齐。把轨道重新叠加试听,也有助于发现漏掉的内容和明显的分离损伤。

Use cases and prompting

准备一首已完成、可读取的歌曲,按接口要求填写歌曲或任务 ID,再选择支持的分轨类型。这个操作需要源音频,不必编写新的歌曲描述。

例如为了给演示视频降低原曲人声,可先分离人声与伴奏,下载两条音轨,在剪辑软件里保持起点对齐,再降低人声轨音量。

保存分轨任务 ID,等成功后逐条试听。检查是否存在伴奏漏入人声、尾音截断或金属感;需要进一步混音时,保留完整长度的音轨,并与原曲对照。
