Stem Splitter

This free stem splitter separates a finished song into its component parts so you can work with them individually — the vocal on one side, the backing on the other. Splitting a mix into stems is the starting point for remixing, sampling, making a karaoke track, practising an instrument against the rest of a band, or lifting a drum break out of a record. The tool analyses the stereo field and the spectral content of the file to decide what belongs where, then renders each stem as a separate download. It runs on the Web Audio API inside your browser, so the track never reaches a server and unreleased material stays private. Separation quality depends heavily on the source: a modern, well-mixed pop record with a centred vocal splits cleanly, while a dense wall-of-sound mix, a mono recording or a heavily bussed live album gives the algorithm much less to work with. Expect artefacts on cymbals and reverb tails, which are the hardest things for any separation method to attribute to one source.

How the stem splitter works

Centre · 180 Hz – 9 kHzSides · low end + air

Lead vocals are mixed dead centre, so they sit identically in the left and right channels. Subtracting one channel from the other cancels everything centred — but only between roughly 180 Hz and 9 kHz, so the kick, the bass and the cymbals survive intact.

We measured how much of the vocal actually disappears, and what it costs the rest of the mix, across a set of commercial recordings — the method and the numbers are in our study on measuring centre-channel separation, including the cases where this approach fails outright.

Stem Splitter: what people search for

Searched as a stem splitter, a song stem splitter, an audio stem splitter, a best stem splitter comparison, a song separator, an audio splitter, a track separator and "how to split a song into stems" — also as an ai stem separator or a music unmixer. All of them describe reconstructing the individual parts of a finished mix, which is a fundamentally different job from cancelling whatever sits in the centre of the stereo image.

What the stem splitter handles

The cases people actually bring to it.

A stem is a submix of one part of a song — the vocals, the drums, the bass — bounced as its own audio file. Working with stems lets you rebalance, remix or remove one element without touching the rest.
Load the file into this stem splitter. It separates the mix in your browser and lets you download the individual parts as WAV files, without an account or an upload.
A vocal remover cancels the centre of the stereo image, which takes the kick and bass with the voice. A stem splitter attributes sound to sources, so the instrumental keeps its low end. The splitter is slower but the result is far more usable.
Reverb tails and cymbals are spread across the spectrum and belong to several sources at once, so any separation method has to guess. Dense mixes and heavy limiting make the guessing harder, which is where watery or phasey artefacts come from.

Stem Splitter — frequently asked questions

What is a stem in music?

A stem is a submix of one part of a song — the vocals, the drums, the bass — bounced as its own audio file. Working with stems lets you rebalance, remix or remove one element without touching the rest.

How do I split a song into stems for free?

Load the file into this stem splitter. It separates the mix in your browser and lets you download the individual parts as WAV files, without an account or an upload.

How is a stem splitter different from a vocal remover?

A vocal remover cancels the centre of the stereo image, which takes the kick and bass with the voice. A stem splitter attributes sound to sources, so the instrumental keeps its low end. The splitter is slower but the result is far more usable.

Why do the stems have artefacts?

Reverb tails and cymbals are spread across the spectrum and belong to several sources at once, so any separation method has to guess. Dense mixes and heavy limiting make the guessing harder, which is where watery or phasey artefacts come from.

What kind of songs split most cleanly?

Modern pop, hip-hop and electronic records with a clear centred vocal and separated instruments. Live recordings, mono sources, and mixes with heavy bus compression are the hardest cases.

Can I release a remix made from split stems?

Only with permission from the rights holder of the original recording. Separating stems does not create new rights — for private practice and study it is fine, but a public release needs clearing.
