How to split a song into stems

Drop your song

Drag an MP3, WAV, M4A or FLAC file, or a video, onto the page, or click to choose it.

Split it

Pick WAV, MP3 or M4A and press Separate. The first run downloads the model once.

Download the stems

Play each stem beside the original, then download one, or both with one click.

Split a song into stems in your browser

Drop a song and split it into two stems, the vocals and the instrumental, with the open Spleeter model. Listen to each stem beside the original on one timeline, then download one or both as WAV, MP3 or M4A. Everything runs in your browser, so the song stays on your device.

How the stem splitter works

The page runs Spleeter's two-stem model, made by Deezer and released under the MIT licence, through ONNX Runtime in your browser, on the graphics chip when the browser offers one and on the processor otherwise. Your browser downloads the model once (about 38 MB) and keeps it. The song is split in pieces of about 12 seconds that are joined back with a short crossfade, so both stems are exactly as long as the song and start on the same sample, ready to stack in a DAW. Only want one of them? The Instrumental Maker leads with the music and the Acapella Extractor with the voice.

Open any song, save WAV, MP3 or M4A

The stem splitter opens MP3, WAV, M4A and AAC, FLAC, OGG, Opus and WEBM audio, plus the sound of a video file such as an MP4, MOV, MKV or WEBM. Each stem is saved as WAV, MP3 or M4A, in stereo at 44.1 kHz. WAV is the format to take into a DAW.

The song stays on your device

The song is read, split and saved by your browser, so it stays on your device. Nothing is downloaded but the separation model, once, so the first run needs a connection; after that the model is kept in the browser.

Limits

The splitter gives two stems, vocals and instrumental. On a current Chrome, Edge or Firefox on a computer, or Safari, it sets no length limit of its own, because the song is read in pieces. Very old browsers and a few formats, such as AVI and AC-3 audio, go through a fallback decoder that handles up to 30 minutes, and 10 minutes on a phone. A WAV stem can be up to 2 GB; for anything longer, choose MP3.

Frequently Asked Questions

What stems do I get?

Two stems, the vocals and the instrumental with everything else. Played together they give back close to the original song. Splitting the music further, into drums or bass, is not something this page does yet.

Which model splits the stems?

Spleeter, the open separation model made by Deezer and released under the MIT licence, in its two-stem version. It runs in your browser through ONNX Runtime, so no server sees the song.

Can I split a video's soundtrack?

Yes. Drop an MP4, MOV, MKV or WEBM video and the splitter takes its sound and splits it into the vocals and the instrumental. The stems are audio files; the picture is not kept.

How long does a split take?

It depends on your device and browser. A recent graphics chip splits a song much faster than the processor does, and a phone takes the longest. The page shows which part of the song it is on and about how long is left.
