Suno 重构音轨分离功能，推出三种拆分方式
We’ve made improvements to Stem Separation By Team Suno·Jun 11, 2026 Extracted stems are crisper, cleaner and ready to drop into your track Announcements Product Update
Suno 对音轨分离功能进行重构，推出三种拆分方式：Auto Split 将歌曲自动拆分为最多 12 个音轨（鼓、贝斯、吉他等）；Split from Mix 可隔离或移除特定乐器/人声并生成伴奏轨道；Advanced Split（仅 Premier 订阅）支持从近 100 种乐器中精确提取目标音轨。与常规切割算法不同，Suno 使用最新模型从零重新生成每个音轨，而非从混音中切割，以消除串音和音质损失。该功能适用于 Pro 和 Premier 订阅用户，可用于 Suno 创作或上传的音乐。
Suno 重写了 stem separation，不再是旧路子切音频，而是用模型重新生成干净的干声，鼓点有劲、人声没杂音，还能拆上百种乐器，做混音的人可以试试。
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.
