Suno 改进 Stem Separation，推出 Auto、Split from Mix 与 Advanced 三种分离模式

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.
