vocalremover.org
Splits a song into a vocal track and a backing track.
Upload a song and it returns the isolated vocal and the instrumental, separated by a model rather than by the old phase-cancellation trick, so it works on stereo mixes where that always failed. The same site carries a pitch shifter, key finder, BPM detector and a simple cutter, which covers most of what a band or a karaoke night needs. Nothing here needs an account.
Questions
Works the moment the page loads. No account, no email, no trial. The track is uploaded to their servers, and dense or heavily compressed mixes come back with audible artefacts in both stems.
Yes. Vocal Remover sends your input to its own servers to process it. That is fine for public material; for anything containing personal data, use one of the on-device tools instead.
