How to split a song into stems in three steps
Bring in the song
Upload a local audio file or choose a track from your library. A clean, high-quality source splits into cleaner parts than a low-bitrate rip, so start from the best copy you have.
Pick the model for the breakdown
Echo Basic gives the basic split. Choose Echo Advance or Echo Pro when you want the track broken into more individual parts, or pulled apart more cleanly on a dense mix.
Split and take the parts
Run the Split and each layer comes back as its own track. Solo them to check for bleed, and if a busy song smeared two parts together, run it again a tier up.
Mute one, boost another, swap a third
Once the parts are separate, you can touch them one at a time. Pull the drums down, bring the bass up, mute a layer that is fighting the mix, or drop in a fresh recording where an old part was. None of that is possible while the song is a single locked file. That control is the reason to split into stems instead of a plain two-way cut. You are not choosing between the voice and the music, you are getting a mixing desk back for a song that only ever existed as a bounce.
Open the mix and see the parts
A finished song is a stack of layers glued into one file. The AI Stem Splitter pulls that stack back apart, so the pieces that got printed together, the kind of parts a mix is built from like the drums, the bass, the vocal, come out as separate tracks again. That is a different thing from lifting the voice off the top. Here you get the components, each on its own, which is what you need when the job is not keep-one-drop-the-rest but rework the song from the inside.
Why split your stems here
An AI stem splitter that opens a song into its separate parts, so you get per-layer control instead of a single keep-or-remove cut.
The whole song, in parts
You get the layers of the track as separate files, not a two-way split. That is a mixing desk handed back for a song that only existed as a finished bounce.
Rebalance, do not merely remove
With every part separate you can turn one down, push another up, or swap one out. Control at the layer level, not a binary keep-the-vocal-or-not.
More parts when you need them
The tier sets how finely a track breaks apart, so a higher Echo model gives more individual layers when the basic split is not enough for the rework.
Solo a layer to study it
Isolating the bass or the drums to learn or transcribe a part is a first-class use here, not an afterthought. The part you want comes out clearer than picking it from the mix.
It covers the simple cuts too
A vocal or an instrumental is just the two-part case of this split. One tool reaches from a quick acapella all the way to a full multi-part teardown.
Free to try the basic split
Echo Basic costs nothing, so you can run a track, hear how it separates, and only move up a tier for the songs that need a finer or cleaner breakdown.
Full Toolkit
Once the song is in parts
Stems are the starting point for a rework. The rest of SunoPrompt handles the simpler cuts and the new parts you build.
Acapella Extractor
When you only want the voice, not the full teardown. The Acapella Extractor makes the two-part cut and hands back a clean isolated vocal.
Instrumental Maker
The other simple cut. Drop the vocal and keep the backing when a full stem breakdown is more than the job needs.

What the AI Stem Splitter does
The AI Stem Splitter separates a finished song into its individual stems, the separate layers a mix is built from, so you can solo, rebalance, replace, or remix any part instead of working with one locked file.
A stem is one layer of the song
In production, a stem is a single component of a mix printed on its own: the drum stem, the bass stem, the vocal stem, and so on. A finished track flattens all of them into one file. This tool reverses that, returning the layers as separate tracks so each one can be handled by itself.
A full teardown, not a two-way cut
Keeping the vocal or dropping it is a single split down the middle. Stem splitting breaks the song into several parts at once, which is a different order of control. The Acapella Extractor and the Instrumental Maker are the simplest version of this, the two-part case, and stem splitting is the same idea taken all the way.
How many parts you get
The tier sets the granularity. Echo Basic makes the basic split, and Echo Advance and Echo Pro break the track into more individual parts, so the layers that Basic leaves bundled come out on their own. Match the model to the job: reach higher only when you actually need the finer breakdown.
The point is per-part control
Separate stems mean you stop treating the song as one thing. Rebalance a mix that was mastered too loud, mute a part that clashes, re-fx just the drums, or replace a weak layer with a new take. This is the difference between editing a photo and editing the layers the photo was flattened from.
Solo a part to learn it
Not every use is a remix. Soloing the bass to transcribe a line, isolating the drums to study a groove, or pulling one part out to practice against it are everyday reasons to split a song. The stem you want alone is often clearer than trying to pick it out of the full mix by ear.
How clean the parts come out
Honest version: separation is strong but not surgical on every track. On dense mixes some bleed can survive between neighboring parts, a hi-hat ghosting into another stem, for instance. This is where the model tier matters, so a higher Echo model is worth it when the arrangement is thick and the parts overlap.
How it differs from other separation tools
It is a full teardown, not a single cut. You get the layers of the song as separate parts, rather than one vocal-versus-music split.
Every part comes out on its own, so you can rebalance and replace inside the mix, rather than only keeping or removing one thing.
The tier changes granularity, not merely cleanliness. A higher Echo model breaks the track into more parts, which is a different axis than a cleaner two-way strip.
The acapella and the instrumental are its simplest split. Stem splitting is the same engine taken further, so a two-part cut is just the basic case of it.
You can solo any layer, which most removers do not offer. Isolating one part to study or reuse is built into having every stem separate.
