Frequently asked questions
How does vocal removal work here?
Lead vocals are usually mixed dead-center, equally in the left and right channels. Subtracting one channel from the other (L − R) cancels anything centered — including the vocals — while off-center instruments largely survive. It’s a classic phase-cancellation trick, not AI stem separation.
Why do the results vary so much?
It works best on songs with strongly centered vocals and instruments spread to the sides. Anything else centered (bass, kick drum, snare) gets removed too, and reverb or backing vocals panned to the sides will remain. Results differ from track to track.
It says my file is mono — why can’t it work?
The technique needs two different channels to subtract. A mono file has identical (or single) channel data, so there’s nothing to cancel. You’ll need a true stereo recording.
Is my music uploaded anywhere?
No. The file is decoded and processed entirely in your browser with the Web Audio API, and the WAV is built locally. Your song never leaves your device and is never uploaded.
