How does vocal removal work?

ProRemover uses phase-cancellation of the stereo center channel, where lead vocals usually sit, plus a tunable band filter to preserve instruments. It works best on true-stereo studio mixes.

Frequently asked questions

Is ProRemover really free?

Yes — completely free, no sign-up, no watermark. It's part of the StudioMixPro toolset.

Does my audio get uploaded?

No. Everything runs in your browser via the Web Audio API. Your file never leaves your device.

Which files can I use?

Any format your browser can decode — MP3, WAV, FLAC, M4A, OGG. Output is exported as WAV.

Why aren't the vocals gone completely?

Browser-side removal cancels the stereo center where vocals usually sit. It shines on true-stereo mixes; heavily mono or reverb-drenched vocals are harder. For AI-grade stem separation try RemoverPro.
