Free online stem splitter & vocal remover

A stem splitter — also known as AI source separation, a song splitter or a vocal remover — takes a finished, mixed-down track and pulls it back apart into its individual stems: vocals, drums, bass, guitars and other instruments. It used to require the original studio session files, but our AI stem separation does it from a single MP3 or WAV in minutes, free and online with nothing to install.

Whether you want to separate vocals from a song, remove vocals to make an instrumental, or extract an acapella for a remix, this tool gives you clean, downloadable tracks you can drop straight into your DAW. Upload the highest-quality file you have — the cleaner your source mix, the cleaner every stem the model returns.

How AI stem separation works

Classic vocal removers relied on a phase-cancellation trick (subtracting the left channel from the right) that only worked on perfectly centred vocals and left obvious artefacts. Modern AI stem separation is completely different: a deep-learning model has been trained on thousands of multitrack songs, so it recognises what a voice, a kick drum, a bassline or a guitar actually sounds like and reconstructs each one as its own track. That's why this online stem splitter can isolate parts cleanly even when they overlap in the same frequency range.

Stem splitter vs. vocal remover

A vocal remover is simply a stem splitter used for one job: keep the instrumental and drop the vocal. This tool does both and more — export the isolated vocal for an acapella, the instrumental for karaoke, or the separated drums, bass and other parts for sampling and remixing. One upload, every stem.

What you can do with separated stems

• Make acapellas & instrumentals for remixes, mashups, edits and DJ tools.
• Sample and flip isolated drums, bass or melodies without the rest of the mix bleeding in.
• Build karaoke tracks by removing the lead vocal from any song.
• Create practice & backing tracks by muting or soloing a single instrument to learn a part.
• Rebalance or re-master an old recording when you only have the stereo bounce.

Get the cleanest stems

For the best source separation results, upload a lossless WAV or FLAC rather than a low-bitrate MP3, and use the cleanest, least-compressed version of the song you can find. Simple, well-recorded mixes separate most cleanly; very dense, heavily-distorted or bass-heavy masters are harder and may leave a little bleed between parts — which is normal for any AI vocal remover or stem splitter.

Supported formats & privacy

The stem splitter accepts MP3, WAV, FLAC, M4A, AAC, OGG and AIFF. Your uploaded file is used only for processing and deleted automatically afterwards — your music is never shared or published. The separated stems are saved privately to your own account history so you can download them again anytime, and you can remove any result whenever you like. It runs entirely in the browser, so you can split stems on Windows, macOS, Linux, Android or iOS without downloading any app.
