Drop in any song and get a clean instrumental to sing over: a real karaoke track with the lead vocal lifted out, free, no account and no watermark.
Split your track free →Old free "karaoke makers" flip one stereo channel to cancel whatever sits dead-centre. That takes the kick and bass down with the singer and only works on perfectly centred mixes. StemGrab doesn't cancel anything: Demucs recognises what a voice sounds like and lifts it out, so the backing stays full and the vocal actually goes away.
Upload the studio version of the song (MP3, WAV, FLAC or M4A). StemGrab returns the instrumental plus every other stem, so if the backing vocals are distracting you can drop the isolated vocal stem back in at a lower level.
Clean, well-produced studio recordings make the best karaoke tracks; live or lo-fi versions leave more vocal bleed. If you only care about the backing, our instrumental maker and vocal remover pages cover the same one-upload flow from the other angle. Singing along to practise is always fine; only publishing someone's recording needs permission — see stems & the law.
The reason a karaoke night falls flat is almost never the instrumental. It's that the song sits in the wrong place for the person holding the microphone. A track recorded by a tenor is punishing for most people, and "just sing it lower" doesn't work when the backing track stays where it is.
StemGrab reads the key and the tempo of your upload and shows both next to the finished stems, which turns guesswork into arithmetic. If the original is in B major and your singer is comfortable up to G, you know you need to come down four semitones, and you can transpose the instrumental by exactly that much in any free audio editor rather than nudging a pitch slider until it sounds less bad. Two things to watch: shifting more than about three semitones starts to make the drums sound rubbery, and pitch-shifting without time-correction will change the tempo too, so use your editor's "preserve tempo" option.
The tempo readout earns its keep separately. If you're running a live band or a click track alongside the instrumental, you need the BPM before you start, not after the first verse falls apart. And if you're cutting the track down to a single verse and chorus, knowing the BPM lets you cut on the bar instead of by ear.
One track is a five-minute job. A set for a party is a small production, and it goes faster if you do it in the right order. Gather the songs first and run them all through the tool in one sitting, because each upload is independent and there's no daily cap to work around. Rename each instrumental as you download it: artist - title (key, bpm).mp3 takes two seconds and saves you opening files blind later in the evening.
Then audition them. Use the mixer on the results page to solo the instrumental and skip straight to the chorus of each one, because the chorus is where stacked backing vocals show up and where a track will either hold up or sound hollow. Anything that sounds thin there is worth keeping the other stem for: mixing a little of it back under the instrumental fills the gap where the harmonies used to be. Finally, order the set so the demanding songs land early, while voices are fresh, and put the easy singalongs at the end.
Lyrics are the one thing StemGrab doesn't produce: it works on audio, not text. Pull the words from anywhere you like and keep them on a phone or a second screen. Everything else, including the instrumental, comes out of the one upload.
Yes — no account, no watermark, no daily cap tricks. The ads around the tool keep the GPU running.
The lead vocal comes out cleanly on most modern mixes. Backing vocals and heavy reverb tails can partly remain, which is true for every separation tool.
Seven per song: vocals, drums, bass, guitar, piano, other, and a mixed instrumental (everything except the vocals), all as 192 kbps MP3 plus a zip of the lot.
The tool is free to use, but the rights to the recording stay with whoever owns them. Practising privately is always fine; for anything you publish — a remix, cover or mashup — get permission first. See stems & the law.
