Vocal Remover & Isolator

Karaoke sites meter their free exports and watermark them; acapella extractors want a subscription. This tool does the vocal separation the classic way — mid/side stereo cancellation, the same trick every "vocal cut" button has used since the karaoke era — entirely in your browser, with no account, no queue, and no watermark. It is instant because there is no model to download: it is pure signal math running on your CPU.

How it works: 1) Drop a stereo song (MP3, WAV, M4A, FLAC). 2) Pick a mode — "Karaoke" strips the centered lead vocal and keeps the instruments (bass included), or "Acapella" isolates the centered content as a vocal track. 3) Preview the result against the original and download as WAV or MP3.

Being honest about the physics: this cancels what is panned dead-center in the stereo mix, which is where lead vocals usually sit. It works well on most stereo recordings, but it cannot separate a vocal that was recorded in mono, already stereo-widened, or baked into a mono file — and some centered instruments share the fate of the vocal. For the huge majority of normal stereo releases it is the free, private, unlimited karaoke maker.
