Free AI Backing Track Maker — Sing Over Any Song

Turn any song into a clean instrumental you can sing, rehearse, audition, or record a cover over. A studio-grade three-model ensemble strips out the lead vocal and leaves the full music behind — in lossless WAV or FLAC, with the key and BPM detected automatically so you know exactly what you are singing to.

How to make a backing track — 4 steps

  1. Upload the song or paste a YouTube / SoundCloud / TikTok URL.
  2. Pick WAV or FLAC. For rehearsing and recording, lossless keeps the drums, bass, and cymbals crisp — MP3 dulls the high end you sing against.
  3. Click Separate. The Studio pipeline runs three transformer-based models and averages their masks to pull the lead vocal out cleanly.
  4. Download the instrumental — loudness-normalized and ready to sing or play over. The page also shows the detected key and BPM.

What makes a good backing track?

A backing track you can actually perform to needs three things: no vocal residue (you don't want the original singer bleeding through while you sing), preserved musical detail (the groove of the drums, the body of the bass, the ring of the cymbals — the things that keep you in time and in tune), and steady loudness (so it sits at a comfortable level against your own voice).

Old "vocal remover" tricks used phase cancellation, which gutted the center of the mix and took the bass and snare with it. Modern AI models like BS-Roformer learn what a voice looks like in the spectrogram and remove only that, leaving the instrumental full and musical. Our ensemble blends three of the best models so no single model's weakness shows up in your practice track.

Who uses AI backing tracks

🎤 Cover singers

Record a cover of any song without waiting for an official instrumental — pull one straight from the track you love.

🎯 Vocal practice

Rehearse phrasing, breath, and pitch over the real arrangement instead of a cheap MIDI karaoke version.

🎬 Auditions & covers online

Sing over a clean instrumental for an audition tape, a TikTok cover, or a YouTube performance.

🎸 Live performers

Build a minus-one track for a gig where you sing or play the lead part live over the backing.

🎓 Music teachers & students

Practice a piece with the melody removed, using the detected key and BPM to transpose to a comfortable range.

🎧 Content creators

Use an instrumental bed for a video, a duet, or a reaction without the original vocal fighting your own audio.

Why our backing tracks beat other free tools

Frequently asked questions

Will the backing track still have the original singer in it?

No — the AI removes the lead vocal (and the harmonies and ad-libs). On a clean modern studio mix you'll hear essentially no voice. Heavily processed or live tracks can leave faint residue.

Can I lower or raise the key to fit my voice?

The tool tells you the song's key and BPM. To actually transpose, drop the downloaded instrumental into a DAW or a free pitch-shift app — a clean stem transposes much more naturally than the full original mix.

How long can the song be?

Up to 20 minutes per track, up to 100 MB per file. A typical 3–4 minute song finishes in about 6 minutes.

Is singing a cover over this legal?

Practicing and recording covers for yourself is generally fine. Releasing a cover commercially needs a mechanical license for the song, the same as any cover — the AI step doesn't change the underlying rights.

What about the backing vocals — can I keep them?

Not separately. The model treats all singing as "vocal," so harmonies go out with the lead. What's left is a purely instrumental backing track.

Free tier: how many backing tracks?

3 songs per month free once you sign in (1 free to try without an account), or more with Patreon Pro or pay-as-you-go credits.
