Turn a song into a karaoke-style instrumental using phase cancellation. The vocal remover processes your file locally and exports MP3 or WAV.
The tool uses phase cancellation (center-channel removal): (L − R) / 2. In a stereo mix, vocals are usually panned dead center (identical in L and R) while instruments are spread to the sides (different). Subtracting the channels cancels the centered vocals and leaves the side instruments, producing an instrumental track. Everything runs locally — no upload.
It only works on stereo files. It only removes vocals that are truly centered — modern mixes with slightly off-center, doubled, or reverberant vocals will not be fully removed. Instruments also panned center (bass, kick, snare) get removed too, so the instrumental can sound thin. It removes vocals but cannot isolate them into a separate file.
If results are poor, use AI-based separation: Spleeter or Demucs (open source) — e.g. `python -m demucs song.mp3` outputs vocals.wav and no_vocals.wav. Or try Ultimate Vocal Remover (free desktop) and online services like Moises, Lalal.ai, Fadr.
