每首歌都是各种声音的复杂融合。Stem separation（音轨分离）让你能够把这种融合拆解成一个个独立的元素，这项突破性技术正在重塑专业人士和初学者的音乐创作方式。
Stem separation 已经在 Suno 工作流中存在一段时间了——提取人声、分离乐器、制作清唱或伴奏音轨，或者为你的 DAW 准备多轨素材。但你一次次大声地告诉我们，你想要更干净的结果，并且希望对歌曲如何拆分有更多掌控权。所以我们把它重建了。
三种拆分方式：现已在 Suno 上线
Auto Split 是我们最初的 stem separation 选项，它会自动完成分类，把一首曲目拆分为最多 12 个 stem——鼓、贝斯、吉他、键盘、木管乐器等等。它稳定可靠，但不如更新后的选项精准。Pro 和 Premier 套餐可用。
Split from Mix 是此前 Vocal + Instrumental 工具的升级版，适用于你想专门分离或移除某一个声部的场景。从下拉菜单中选择一种乐器或人声，你就会得到一个干净的 stem，外加一条包含其余所有内容的配套音轨。例如，提取主唱人声后，你还会得到去掉人声的完整歌曲——这对想把 Suno 歌曲变成个性化 demo 的歌手，或想跟着伴奏练习的吉他手和鼓手来说非常完美。Pro 和 Premier 套餐可用。
Advanced Split是全新功能，将我们最新音轨分离技术的全部能力交到你的手中。在近 100 种乐器的列表中搜索，精准提取你想要的音轨——不多，不少。把大提琴从弦乐组的小提琴中分离出来。也可以找特雷门琴、铃鼓或迪吉里杜管。少数最精细的选项仍在开发中，因此它们会随着时间不断改进。仅限 Premier 套餐使用。
Suno 的音轨分离之道
许多音轨分离工具像手术刀一样工作：它们拿走你完成的歌曲，试图把它切回到当初输入的各个部分，隔离频段并指望切口能干净利落。结果可能难以预测：各部分之间串音、水声般的伪影、缺乏全频段冲击力的鼓声。
我们选择了另一条路。Suno 不是把你的歌曲切开，而是倾听它，并用我们最新的模型从零开始重新生成每一条音轨。当你提取一把原声吉他时，你得到的不是从原始混音中雕刻出来的一片。你得到的是一把全新生成的吉他，与原有内容相符，干净利落地独立呈现。
这就是为什么这些音轨听起来如此——有力、清脆、没有串音，可以直接放进你 DAW 的时间线或 Suno Studio 中使用。
你可以对在 Suno 上创建的任何歌曲运行音轨分离，也可以对你上传的自己的音乐进行分离。音轨分离是付费功能，因此你需要订阅才能使用。

创建关于
Every song is a complex blend of sounds. Stem separation unlocks the ability to pull that blend apart into its individual elements, a breakthrough that is reshaping music creation for professionals and beginners alike.
Stem separation has been part of the Suno workflow for a while — pulling a vocal, lifting an instrument, creating an acappella or backing track, or prepping a multitrack for your DAW. But you told us, loudly and often, that you wanted cleaner results and more say in how a song comes apart. So we rebuilt it.
Three ways to split: now live on Suno
Auto Split is our original stem separation option that does the sorting for you, breaking a track into up to 12 stems — drums, bass, guitar, keys, woodwinds, and more. It’s reliable but less precise than the updated options. Available on Pro and Premier.
Split from Mix is an update to the previous Vocal + Instrumental tool, and is for when you want to isolate or remove one part in particular. Pick an instrument or voice from the dropdown and you'll get a clean stem, plus a companion track with everything else. Pull the lead vocal, for example, and you also get the full song minus the vocal — perfect for singers turning a Suno song into a personalized demo, or guitarists and drummers practicing over a backing track. Available on Pro and Premier.
Advanced Split is brand new and puts the full power of our latest stem separation technology in your hands. Search a list of nearly 100 instruments and extract exactly what you want — nothing more, nothing less. Separate a cello from a violin in your strings section. Reach for a theremin, a tambourine, or a didgeridoo. A few of the most granular options are still in development, so they will get better over time. Available on Premier only.
The Suno approach to stems
Many stem tools work like a scalpel: they take your finished song and try to slice it back into the pieces that went in, isolating frequencies and hoping the cuts land cleanly. The results can be unpredictable: bleed between parts, watery artifacts, drums that lack full-range punch.
We took a different path. Instead of cutting your song apart, Suno listens to it and regenerates each stem from scratch using our latest model. When you extract an acoustic guitar, you're not getting a carved-out slice of the original mix. You're getting a freshly generated guitar that matches what was there, rendered cleanly and on its own.
That's why these stems sound the way they do — punchy, crisp, free of spill, and ready to drop straight into your timeline in your DAW or on Suno Studio.
You can run stem separation on any song you've created on Suno, as well as your own music you upload. Stem separation is a paid feature, so you'll need a subscription to use it.
