— 04 · The Model

The best
open-source
separation model.
Built in.

BS-RoFormer SW is the highest-scoring music source separation model available today. Compiled to Apple CoreML and shipped natively inside SPLIT — no cloud, no GPU rental, no dependencies.

Scores that were impossible two years ago.
Now running natively on your Mac.

↳ SDR measured on MUSDB18 benchmark. Higher = cleaner separation. Source: ISMIR 2025 evaluation.

— 05 · Four Modes

Pick your decomposition.

Four separation depths. Same engine. Choose what fits the track — from a fast vocal pull to a full ensemble decomposition.

Vocals + Instrumental. For remixes, karaoke, sampling.

Vocals · Drums · Bass · Other. The industry standard split.

Vocals · Drums · Bass · Guitar · Piano · Other. Full decomposition. Nothing hidden.

Ensemble mode: BS-RoFormer + MelBand Roformer. When every decibel of clarity matters.

— 06 · Workflow

Three steps. Zero friction.

Drop

Drag any audio file. WAV, MP3, FLAC, M4A, AIFF, OGG. Or click Browse. That's the hardest part.

Split

BS-RoFormer processes your track locally. Watch the progress bar. Preview each stem in real time. Solo the vocals. Mute the drums. Adjust the faders.

Create

Export all 6 stems as WAV or FLAC. Or hit Send to Mixcraft and let AI analyze, generate mixing recipes, and push them to BALANZE. From stems to finished master. One ecosystem.

— 08 · The Ecosystem

From stems
to finished master.

Your Mix A finished stereo track. WAV, MP3, FLAC — anything you've got.

SPLIT Separates the track into 6 pristine stems. Locally. No upload.

Mixcraft AI classifies tracks, detects masking, generates mixing recipes.

Balanze Canal Applies per-channel processing: EQ, Compression, Color.

Balanze Master Coordinates the bus, images the stereo field, maximizes the loudness.

Finished Master Mixed. Mastered. Ready for release. One ecosystem, end-to-end.

No other stem separator does this. SPLIT isn't just a tool —
it's the entry point to the first mixing ecosystem that thinks, executes, and teaches.

— 09 · What Producers Are Saying

Working in the field.

I stopped paying for LALAL.AI the day I got SPLIT. Same quality, runs on my laptop, no internet needed.

— ProducerLos Angeles, CA

The 6-stem mode is insane. Guitar and piano separation that actually sounds clean.

— Mix EngineerLondon, UK

Send to Mixcraft changed my workflow. Separate, analyze, mix — all in one ecosystem.
