Need a backing track to practise a song, rehearse a church special number or run karaoke night at home? The instrumental maker takes a stereo song from your device and lowers the lead vocal so you can sing over it. It’s free, there’s no sign-up, and the file never leaves your phone or computer.
How it works
- Choose a stereo song or beat from your phone or computer. Nothing is uploaded.
- Your browser splits the audio into thousands of short slices and compares the left and right channels in each frequency band.
- Sound that is identical on both sides (the centre of the mix, where lead vocals usually sit) is estimated and removed for the instrumental, or kept on its own for the acapella.
- Bass and kick drum below about 120 Hz are left alone by default, so the beat keeps its weight.
- Preview the result, then save it as MP3 or WAV.
Frequently asked questions
Can I upload my instrumental to YouTube, TikTok or Audiomack?
Only with permission. An instrumental made from someone else's song still contains their recording, so posting it, selling it or using it for a cover release needs a licence from the rights holders. Platforms detect these uploads and can mute, block or claim them. For your own songs, or beats you have licensed, go ahead.
How do I get the best instrumental?
Start from the best-quality stereo file you have (a WAV or a 320 kbps MP3 rather than a WhatsApp forward). Leave "Keep bass and kick" on, try Normal first, then Strong if the voice is still clear. Save as WAV if you will edit it further, and check the result on headphones.
Why is the instrumental quieter in the middle?
Everything that sits in the centre of the mix is reduced, and in many songs that includes parts of the snare, lead instruments and some of the vocal reverb. That is the trade-off of this method. The volume tool on this page can bring the overall level back up afterwards.
Can I find the key and tempo of my instrumental?
Yes. Download it, then drop it into our free Beat Lab BPM and key finder to get the tempo, key and Camelot code before you write or practise.
Is my audio uploaded anywhere?
No. Your file is opened and processed inside your browser on your own phone or computer. It is never sent to Centertainment or anyone else, so unreleased songs and private voice notes stay with you. The page only downloads the tool itself (and a small MP3 encoder file) from our site.
Is Audio Lab free?
Yes. Every tool on this page is free, with no sign-up, no watermark and no daily limit. Free files can be up to 10 minutes long (8 minutes for the vocal remover). A Pro version with high-quality cloud stem splitting, batch processing and longer files is planned; you can join the waitlist, and nobody is charged anything today.
Terms of use and copyright
- Only process audio you own or have permission to use: your own recordings, beats you have licensed, or tracks whose licence allows editing. Removing vocals, cutting or converting a song does not give you any rights to it.
- Don't publish, sell, stream or perform results made from other people's music without permission from the rights holders. Platforms may mute, block or claim such uploads, and you are responsible for how you use what you make.
- Audio Lab does not download or fetch audio from links (YouTube, TikTok, Instagram, Spotify, Audiomack, Boomplay or anywhere else) and does not host any music. You choose files that are already on your device.
- Your files are processed in your browser and never uploaded to Centertainment. We don't see, store or keep copies of your audio. Voice notes may contain other people's voices: respect their privacy.
- The tools are provided free and "as is". Results are automatic and can contain artefacts, so check them before you share, and keep your original files.
Who it’s for
- Singers and worship teams: rehearse your part over the band, then switch to acapella mode to hear the original melody on its own.
- Karaoke at home: turn songs you own into quick sing-along tracks for a party.
- Producers and songwriters: pull a rough instrumental from your own bounced mix when the project files are lost.
- Dancers and teachers: make a practice track with less singing to count over.
Step by step
Choose the song, keep “Instrumental” selected and press Make it. Listen to the preview on headphones. If the singer is still easy to hear, try Strong; if the drums or keys sound hollow, try Gentle. Download as MP3 for your phone or WAV if you will edit it further. Then use the MP3 cutter to trim the intro, or the volume tool on the Audio Lab page to bring the level back up.
About copyright
An instrumental made from someone else’s recording still belongs to them. Use it privately, and get permission (a licence) before you post a cover, sell it or play it in public where that needs a licence. YouTube, TikTok, Audiomack and Boomplay can detect these uploads and mute or remove them. If you want a beat you can release on, license one from a producer, or check its tempo and key in Beat Lab before you write.
Why it’s free
Because all the work happens on your device, it costs us nothing to run, so we don’t need to limit you. The free method has limits of its own: it removes what sits in the centre of the mix, not just the voice. Cleaner AI separation into vocals, drums, bass and other instruments is planned for Audio Lab Pro.
