It uses center channel removal. The tool subtracts the left and right audio channels, which cancels out everything panned to the center of the stereo mix — typically where vocals sit — while leaving side-panned instruments intact. It runs entirely in your browser using FFmpeg, so your audio never leaves your device.
Center channel removal works best on studio stereo recordings where vocals are cleanly centered. Mono recordings, live performances, and songs with heavily panned or reverb-heavy vocals will produce artifacts and bleed-through. There is no way around this with a frequency-based tool — for perfect separation you would need AI-based stem splitting.

MP3, WAV, M4A (AAC), FLAC, and OGG Vorbis. Choose MP3 for small, universally playable files, WAV or FLAC when you need lossless quality for further editing, and OGG or M4A when you need better compression than MP3 at the same bitrate.
