What format is the result saved in?

It downloads as WAV. If you need MP3 or another format, the file converter on this same site handles it — also entirely in your browser, with no upload.

Can I make one on a phone?

Yes. Fast splits vocals from the backing on a phone. The models that split further need a PC.

The original key is too high for me. Can I lower it?

Not on this page, but the key and tempo tool on this site does it. Make the backing here first, then take that file across — doing it in that order sounds better, because a voice is the part where processing is most audible, and transposing while the vocal is still in the mix gives the treatment away.

Can I use the backing track in a stream or a video?

The rights in the underlying song stay with whoever holds them; making a backing track does not change that. Whether you may use it on a given platform depends on the licensing that platform has in place with rights holders. Check that platform’s terms for your own case — this tool only does the processing and cannot make that judgement for you.

The instrumental break is too long. Can I shorten it?

Not here — there is no editing on this page. Take the exported WAV to the audio trimmer on this site and cut the section out there. Separate first, then trim: cutting before you separate can change the result around the edit point.

Is it really free? Do I need to sign up?

It’s completely free with no account needed. Just open the page and pick a file.

Is the song I choose sent anywhere?

No. All separation happens entirely inside your browser.

Which file formats are supported?

MP3, WAV, M4A, AAC, FLAC and OGG, plus the audio track of video files.

One mix, separated into its individual parts

Making a karaoke track means removing the lead vocal and keeping the band. Unlike a commercial karaoke version, what remains is the original recording itself — same tempo, same key, same arrangement you have been listening to.

That difference shows up more than you would expect. A karaoke-bar backing is a re-sequenced version, and its instrumental breaks and fills often do not match the record. A backing made from the record itself means the cues you already learned still land where you expect them. What you do not get is the bar machine key control — if the original sits too high, take the result to the key and tempo page and lower it there.

For practice, how natural the backing sounds matters more than anything. This tool keeps the low end and the top end intact while the voice is removed, so the groove and the chords do not thin out. Output is WAV; if you want an MP3 for your phone, the file converter on this same site handles it without an upload.

The songs that come out best have the lead vocal placed clearly in the centre. Heavily layered vocals, long reverb tails on the voice, and thick stacked harmonies are the ones that leave traces in the backing. When the traces bother you, re-running on High Quality instead of Standard is the thing most likely to change them.

Highlights

Major audio formats: Create from MP3, WAV, M4A, FLAC, and the audio of video files.
Save right after processing: When separation finishes, download the result as WAV straight away.
Your audio stays local: Everything is processed in-browser, so your song never sits on a server.
Practice-ready quality: Vocals come out while the low and high end keep their feel, for an easy-to-hear backing track.

Three simple steps

Open a file
Choose an MP3, WAV, M4A, FLAC or video with “Open file”, or drag it into the workbench.
Check settings and separate
Standard is the baseline for a karaoke track. On a phone, Fast (vocals plus backing) is the one that runs. Check the settings selected for this task, then press “Separate”.
Listen and export
Use Solo and Mute to listen to the parts you need, then choose “Export” to save WAV or MP3.

Practice with the extracted audio

Save the accompaniment, then change its key to suit your voice. Keep the original and listen to the changed audio before practicing.

Switch to “Pitch & tempo” in this workspace to use the audio with the current Solo and Mute settings. No file selection is needed. Export the separated parts as WAV or MP3 first if you want to keep them before further processing.

How many semitones should you lower a song by?
The original sits too high and the chorus hurts. Lowering the key fixes that — until the low passages stop speaking. Where the useful range is, what it costs in quality, and why the order of operations matters.
How much faster is "tempo +1" on a karaoke machine?
Press tempo +1 and the song speeds up — by how much? Makers do not publish the step size, so here is how to measure it yourself and how to build a practice track at the same speed at home. Changing the tempo does not change the key.
