Stem Splitter: Split Any Song into 5 Stems

Upload a song and the stem splitter gives you five stems, not just vocals and music: vocals, instrumental, drums, bass and other. Hear one song a day free with no sign-up, then keep the whole song for $0.50, with no subscription.

Stem splitter example: one song, five stems

This is a real 30-second excerpt, split by the same stem splitter you use here. Press play, then switch between the original and each stem without losing your place.

Original. The excerpt as released, vocals and instruments together. Start here, then switch stems while it plays.

“Persephone (ft. Vidian, Dimitri Artemenko)” by snowflake, ccmixter.org/files/snowflake/22364, licensed under CC BY 2.5. Stems separated by Stem Split AI.

The excerpt runs from 0:30 to 1:00 of a Creative Commons song and every stem comes from our model. No stem splitter is perfect, so a trace of one part can show up in another; listen on headphones to judge.

Four steps

How to use the stem splitter in four steps

  1. 01

    Choose a song

    Drop an MP3, WAV, FLAC, M4A/AAC or OGG file on the page. It can be up to 90 MB and 10 minutes long. Links to YouTube or other sites are not accepted.

  2. 02

    Wait for the preview

    The stem splitter works on our own servers. The preview of all five stems comes first, usually in about a minute, and you can leave the page and come back.

  3. 03

    Listen to every stem

    Play the five stems for 30 seconds from 0:30 of the song, or from the start if it is under a minute, and mute any of them. It is free: 1 song a day without an account, 5 songs a day when signed in.

  4. 04

    Download the whole song

    Sign in and unlock the full song for 125 credits, which is $0.50. You get all five stems as MP3 (320 kbps) and WAV (16-bit, 44.1 kHz), kept in My files for 7 days.

One song, many jobs

What people use a stem splitter for

Once a song is in parts, you can keep the parts you want. These are the jobs people come to a stem splitter for.

  1. 01

    Remove the vocals

    Keep the music and lose the singer to sing over it, cover the song or use it as background. The instrumental stem is the song without its vocals.

  2. 02

    Make an instrumental

    Get a backing track for a cover, a rap verse, a video or a performance, made from the song you already have.

  3. 03

    Pull out an acapella

    Take the vocals alone for a remix, a mashup or to study a singer, harmony by harmony.

  4. 04

    Make a karaoke track

    Turn a favourite song into something to sing along to at home or at a party, with the lead voice taken out.

  5. 05

    Remix and mash up

    Take the drums and bass from one song and the vocals from another, or rebuild a track with a new rhythm underneath.

  6. 06

    Learn a part

    Hear the bass line or the drum pattern alone, then play along with the instrumental when you are ready. Some players loop the stem for hours.

Tips for using a stem splitter well

  1. 01

    Start from the best file you have

    A WAV, a FLAC or a high-bitrate MP3 keeps more detail for the model to work with than a small, heavily compressed file.

  2. 02

    Use the free preview first

    Every split plays 30 seconds of all five stems before you pay anything. If the preview is not clean enough for your use, the whole song will not be either.

  3. 03

    Expect some bleed on busy mixes

    When a voice and a guitar share the same sounds, a faint trace of one can land in the other stem. Dense, loud mixes are the hardest to separate.

  4. 04

    Check you have the right to use the song

    Only upload audio you may process, and check the licence of the original before you publish a remix or a sample made from its stems.

  5. 05

    Mute a stem in your editor

    After you download, load the five stems into any editing program and mute the one you do not want. Muting the vocals gives a backing track, and muting the bass gives you a part to play.

Good to know

Stem splitter questions and answers

What is a stem splitter?

A stem splitter separates a finished song into its parts, called stems. Stem Split AI splits a song into vocals, instrumental, drums, bass and other, so you can remix it, practise with it or sing over it.

How does the stem splitter work?

It uses Demucs htdemucs, an open-source AI model from Meta AI research, run on our own servers rather than through a third-party AI API. The model listens to the mixed song and estimates each stem from it.

Is this stem splitter free?

Splitting and the 30-second preview are free: 1 song a day without an account and 5 songs a day when signed in. Downloading the whole song costs 125 credits, which is $0.50, and $5 buys 1,250 credits for 10 songs.

Which stems does the stem splitter give me?

Five: vocals, instrumental (drums, bass and other added together), drums, bass and other. A download has all five as MP3 (320 kbps) and WAV (16-bit, 44.1 kHz).

What files can the stem splitter use?

MP3, WAV, FLAC, M4A/AAC and OGG files up to 90 MB and 10 minutes long. It takes uploaded files only, so a link to YouTube or another site will not work.

How long does the stem splitter take?

The preview comes first, usually in about a minute, and a four-minute song is fully split in about three. You can leave the page and come back, and a song you have unlocked stays in My files.

Can the stem splitter remove vocals from a song?

Yes. The instrumental stem is the song without its vocals, and the vocals stem is the voice alone. The vocal remover page shows the same split with the instrumental first.

How good is the stem splitter?

It separates most songs well, but no stem splitter is perfect: a faint trace of one part can remain in another, most often in busy, loud mixes. The free preview lets you judge your own song before you pay.

Do I need the rights to the songs I upload?

Yes. Only upload audio you have the right to process. Your files are only for you and are not published. Copyright owners can send a notice to contact@stemsplitai.com.

How long do you keep my songs?

Uploaded songs are deleted after 1 day and the stems after 7 days. Files are only available to the person who uploaded them, and a song in My files shows as expired once its stems are gone.

Do I need an account to use the stem splitter?

No. You can split 1 song a day and hear its preview without an account. Sign in to split 5 songs a day and to download a whole song, which costs 125 credits (/bin/zsh.50).

Do credits expire or renew like a subscription?

There is no subscription. A one-time purchase adds 1,250 credits, enough for 10 songs, and credits are only spent when you download a whole song, never for a split or a preview.
