How to
# How to remove vocals from a song for free
Published November 12, 2026 .
Open Vocal remover, drop a stereo song you have the rights to use, and click Separate vocals. Open-Unmix runs in the browser and writes two WAVs: a vocal stem and an instrumental made by subtracting that vocal from the mix. Nothing is uploaded. The limit is 8 minutes or 80 MB.
The tool for this is Vocal remover . It estimates the vocal in a stereo mix and gives you that vocal plus the remainder. The vocal file is the acapella. The remainder is the instrumental, which is the karaoke bed. Only process audio you own, recorded yourself, or have permission to modify. The MIT license on the model covers the software, not the recording.
The first run downloads the Open-Unmix vocals network, about 17 MB, plus ONNX Runtime. Later songs in this browser reuse that cache. The samples stay in the tab.
## Steps
- Drop a song you can use Open Vocal remover and drop a WAV, MP3, FLAC, or M4A, or a video with an audio track. The picture is ignored. A WAV, FLAC, or high-bitrate file separates more cleanly than a 64 kbps MP3. A mono file is duplicated to stereo so the network can run. A true stereo mix separates better. The limit is 8 minutes or 80 MB. Use only a recording you have the rights to.
- Click Separate vocals The button reads Separate vocals, then Separating. The first run downloads the Open-Unmix model, about 17 MB, and ONNX Runtime: about 14 MB for WASM, or about 26 MB when this browser loads the WebGPU build. The tool tries WebGPU first. If the adapter cannot run the float16 check, the same job continues on WASM. The status line names which one finished. The song is cut into sections of about 8 seconds, with a little context on either side, and the overlaps are crossfaded. The page says phones are happier under 3 minutes. That is not a second hard limit.
- Listen to the vocal and the instrumental Two players appear, Vocals and Instrumental. The vocal WAV is the acapella. The instrumental is the mix minus the estimated vocal, so whatever the model did not call vocal stays in the bed, including the high end above the model's useful band. Listen on headphones before you use either file. Reverb, doubles, and live-room bleed can leave some vocal in the instrumental. Dry, centered studio vocals separate more cleanly than a wet chorus or a phone recording of a band in a room.
- Download both WAVs Each player has Download WAV. The files are stereo WAVs at 44.1 kHz. The names end in -vocals.wav and -instrumental.wav. Keep the WAVs if you will edit further. This page does not make an MP3. Closing the tab drops the players. The source file is unchanged.
## What you get from one split
## What the split will not do
You get a vocal and an instrumental. Drums, bass, guitar, and piano are not separate files. They stay inside the instrumental. If the chorus vocal is still sitting in the bed, the take is probably wet or doubled. This page has no EQ to pull that out. Download the WAV and finish it in your editor.
LALAL.AI and Moises publish more stem types and are often the better choice on a hard mix. The comparison is vocal remover vs LALAL and Moises . Those tools upload the file. This one does not.
## After the split
Cut the hook you need with Audio trimmer . You type a start and an end. The walkthrough is how to trim audio online for free . A ringtone is a different page: Ringtone maker takes a start and a length, caps it at 40 seconds, fades 80 ms at each end, and downloads an .m4r.
Pitch and speed changes the pitch in semitones, or the speed, and downloads a WAV. Speed keeps the pitch. A semitone shift retunes the file and then puts the speed back. BPM and key estimates tempo and key in the tab. Both are estimates, not a lab report. None of these pages upload the file.
## Do this part in Cutshed
- Vocal remover Splits a stereo mix into a vocal WAV and an instrumental WAV with Open-Unmix. 8 minutes or 80 MB. Nothing is uploaded.
- Audio trimmer Cuts a stem to a start and an end. WAV adds a 10 ms fade. MP3 is 192 kbps. 15 minutes or 80 MB.
- Ringtone maker Makes a short hook, capped at 40 seconds, and downloads an .m4r. It does not separate vocals.
- Pitch and speed Changes pitch in semitones or changes the speed, then downloads a WAV.
- BPM and key Estimates tempo and musical key in the browser. Treat both as a starting point.
## FAQ
- How do I remove vocals from a song for free?
Open Vocal remover, drop a WAV, MP3, FLAC, M4A, or a video, and click Separate vocals. You get a vocal WAV and an instrumental WAV. Open-Unmix runs in the browser. There is no account and no credit charge. The limit is 8 minutes or 80 MB.
- Which file is the instrumental and which is the acapella?
The vocal WAV is the acapella. The instrumental WAV is the original mix minus that estimated vocal. That remainder is the karaoke bed. Drums and bass are not their own files.
- Is the song uploaded?
No. The browser downloads the separation model, then runs it locally. The samples stay in the tab and are discarded when you leave or pick another file.
- Why is the vocal still audible in the instrumental?
Reverb, doubles, and live-room bleed share spectrum with the vocal. Dry, centered studio vocals separate more cleanly than a wet or doubled chorus. This page cannot EQ that leftover vocal out.
- What file should I start from?
Start from the least-processed stereo file you have. A WAV, FLAC, or high-bitrate file keeps more of the vocal than a 64 kbps MP3. A mono file is duplicated to stereo. A true stereo mix separates better. Keep the WAV downloads if you will edit further.
- Can I use the result in a video?
The model weights are MIT, so you may use the software commercially. That license does not cover the recording. You still need the rights to the song. Only process audio you have permission to modify.
Files stay on this device.
Free tools never upload the file you open. Studio is the only paid part of the site, and the only place a prompt is sent to a video model.
