How to split a Suno song into stems, and what to do with them

Two ways to get stems from a Suno song: the files in your download, or a stem splitter on the full mix. What you get, how to check the separation, and when stems are worth the effort.

To split a Suno song into stems, use the stems in your download if your plan gives you them. If you only have the full mix, upload it to a stem splitter. Echoteka's splitter returns four WAV files, vocals, drums, bass and other, in one zip, and keeps them for 24 hours. The stems are estimated from the finished mix, so expect a little bleed between them, most audible when a stem plays alone.

Do you need stems at all?

Stems help when you want to change the balance between parts. A vocal that sits too far forward, a bass that smears, drums that need to sit lower: these are stem jobs. A split does not make a mix better by itself. It only gives you control over parts you could not reach before. A full mix that already sounds right needs no split. Mastering is the same either way: master the full mix, and use stems only to fix or rebuild the balance before that step. The download limits guide explains how stems count against a Suno download, so decide before you download.

Two ways to get stems

Source What you get What it costs
Stems from the Suno download, if your plan offers them The parts as Suno exported them Counted within the song's download, under Suno's rules
Echoteka stem splitter, four stems Vocals, drums, bass and other, as WAV files in a zip A free account gets 1 separation a day with four stems. Beyond that, one credit per song, charged only when the separation succeeds
Echoteka vocals and instrumental Two files: the vocals and everything else No account needed for 1 song a day

The splitter takes a song up to 7 minutes long. A failed run is not charged.

Step by step with the splitter

  1. Pick the best file you have. A WAV is best. An MP3 works, but the splitter starts from the same losses.
  2. Choose the mode. Four stems for a full balance change, or vocals and instrumental if you only need a backing track.
  3. Listen to each stem alone. Check for bleed, such as the snare in the vocal stem or the vocal in the other stem.
  4. Download the zip within 24 hours. The files are deleted after that.
  5. Rebuild in your DAW. Keep the stems you change and mix them back together, then master the result.

A worked example

Take a Suno song where the bass blurs in the chorus. Solo the bass stem and check how it sits. If it is the bass that is too loud, lower that stem in your DAW by a small amount, mix the four stems back together, and export a WAV. Compare the new export with the original in the LUFS checker, and check that the true peak still sits at or under −1 dBTP before you master.

Stems also open other jobs. Leave out the drums to make a drumless version, using the remove drums and bass tool. Or change the key of the instrumental, from −6 to +6 semitones with the tempo kept, using the key changer.

Clean first, then master

Stem separation can leave noise that was not in the full mix. If you split stems, clean the separation noise first, then master the rebuilt mix. Do not master each stem on its own. Mastering the stems one by one makes the mix harder to balance and easy to over-process. If the generated artifacts were already in the mix, the AI artifact cleanup works on the whole track.

What stems cannot do

Stems are estimated from the finished mix. They are not the multitrack recording that the producer made.

Goal Do stems help?
A drumless backing track Yes
Practice a bass line Yes, the bass stem on its own
Lower a vocal by a few decibels Yes, if the bleed is small. Listen in the mix
Raise a guitar that sits in the other stem Only partly. The guitar shares that stem with everything else

FAQ

Do I need an account? For four stems, yes: a free account. The vocals and instrumental mode works without one.

How long are the stems kept? For 24 hours, then they are deleted. Download the zip before then.

Are the stems as good as the original tracks? No. Neural separation estimates each instrument from the finished mix, so the stems are close to the original on most songs, not identical to it. The stem splitter page shows what it returns.
