Suno Advanced Split: What to Do With Your Stems Next
Published · by Loopin
The stems are the easy part. What you do in the next half hour — line them up, fix one thing per stem, bounce with headroom and master once — decides whether the split made the song better or just gave you more files.
Only split what you’re going to change
At the time of writing (October 2026), Suno’s release notes describe Advanced Split as a Premier-only mode that regenerates each stem rather than slicing the mix, with a list of nearly 100 instruments to pick from. It costs credits per extraction, so every stem you pull should have a job. Write the job down before you click: “vocal is 2 dB too quiet”, “replace the drums”, “bass is mushy”.
If the only problem is the vocal level, you don’t need Advanced Split at all. Split from Mix gives you the part you pick plus a remainder track with everything else, which is all you need to rebalance one element. Save Advanced Split for songs where you’re actually replacing or reprocessing three or more parts.
Line every stem up at bar one and check what’s missing
Download the stems as WAV, not MP3, and drop them all into your DAW starting at exactly the same point. Set the project to the song’s tempo so you can edit on the grid later. Then play the stems together at unity gain next to the original Suno export and switch between them.
Because Advanced Split regenerates parts rather than cutting them out, the sum won’t match the original sample-for-sample. That’s expected. What you’re listening for is anything that vanished (a pad, a backing vocal, a riser) or a stem whose timing drifts against the drums. If a part is missing, extract it before you start mixing, not after.
Balance with faders before you touch a plug-in
Pull every fader down, bring the drums up until the kick peaks around −10 dBFS on the master bus, then add bass, then vocal, then everything else. Ten minutes of fader balance fixes more than an hour of EQ, and it tells you which stems genuinely need processing.
Keep the master bus clean while you do this: no limiter, no “mastering” preset, no clipper. You want 3–6 dB of headroom on the loudest chorus. A limiter on the mix bus hides balance mistakes and leaves the masterer nothing to work with.
Fix one thing per stem, then stop
Give each stem the single fix you wrote down. Bass: high-pass at 30 Hz and cut 1–2 dB around 250 Hz if it’s woolly. Vocal: cut 2 dB around 300 Hz for mud and use a de-esser at 5–8 kHz if the esses bite. Drums: a transient shaper adding 2–3 dB of attack will bring back snap that the original mix blurred. Our guide to EQing a Suno export has the full frequency map.
What to skip: stereo wideners on every stem, reverb on the regenerated bass, and re-tuning a vocal that already sounds right. Regenerated stems can carry small artefacts; heavy processing makes them louder, not smaller.
Bounce a clean stereo mix and master that
Export the mix as a 24-bit WAV at the project’s sample rate, peaking between −3 and −6 dBFS, with no limiter on the bus. Leave half a second of silence at the start and trim the tail after the last reverb fades. That file is your mix; the stems have done their job.
Then run the bounce through the free online masterer. Start with the default feel, which lands around −14 LUFS with a −1 dBTP ceiling, and use the loudness-matched Original-vs-Mastered A/B so you’re judging tone rather than volume. If you want more weight, try Warm; if it’s a club record, Club sits around −10 LUFS.
Compare against the unsplit version before you release
Master the original Suno export too and put both masters side by side. If the split version isn’t clearly better — clearer vocal, tighter low end, less smear — release the original and keep the stems for a remix. Not every split earns its credits.
When the split version wins, master the final bounce free one more time after any last fader tweaks, export the WAV, and that’s the file you send to your distributor. If you’re weighing whether to master the stems individually instead, read stem mastering vs stereo mastering first.
Frequently asked questions
Is Suno Advanced Split available on the Pro plan?
At the time of writing (October 2026), Suno's release notes list Advanced Split as Premier-only. Auto Split and Split from Mix are the other two modes. Check Suno's pricing page, because plan features change.
How many credits does Suno Advanced Split cost?
Suno documents 10 credits per extraction for Advanced Split at the time of writing, with Auto Split at 50 credits. Costs are charged per instrument you extract, so check the total Suno shows before you confirm and only pull the parts you'll change.
Should I download Suno stems as WAV or MP3?
WAV. You're about to process, sum and master them, and starting from a lossless file avoids stacking another round of MP3 encoding artefacts before the streaming services encode it again.
Why don't my Suno stems add up to the original song?
Advanced Split regenerates each part instead of cutting it out of the mix, so the sum won't match sample-for-sample. Listen for missing parts and timing drift rather than expecting a perfect null.
Do I need to master each stem separately?
No. Balance and fix the stems, bounce one stereo WAV peaking around -3 to -6 dBFS, and master that. Mastering stems individually is a mixing job with extra steps.
What loudness should the final master be?
Around -14 LUFS integrated with a -1 dBTP ceiling suits Spotify and YouTube. Louder genres can go to about -10 or -11 LUFS if the A/B still sounds punchy.
