Vocal Remover
Karaoke trick: cancel the centred vocal and keep the band — honest about limits.
About this tool
Drop a stereo song and choose remove (karaoke) or isolate (rough vocal). The centred signal is cancelled or kept with the bass crossover you set; listen and download WAV. Nothing is uploaded.
Why centre cancellation works, and where it fails
In almost every mix the lead vocal is placed dead centre — identical in the left and right channels — while guitars, keys and backing vocals are panned to the sides. Subtracting one channel from the other therefore cancels the vocal and leaves the sides. The bass and kick drum are centred too, so they'd vanish with the singer; the tool keeps everything below a crossover frequency (default 120 Hz) from the original mix, which restores the low end. Honest results: on a typical modern mix the lead vocal drops dramatically but its reverb tail and any double-tracked or stereo-widened parts remain; on old mono-ish recordings nearly everything cancels; on mixes where the vocal isn't centred, nothing happens. The page measures the stereo width up front and tells you what to expect. AI stem separators — the tools that upload your song to a GPU server — separate far better; this one runs in your browser in a second, costs nothing and never sends the file anywhere. Isolate mode does the opposite, roughly. Fix the level with the normaliser, change the key with audio speed, and shrink with the MP3 converter.
Frequently asked questions
Why can I still hear the singer a little?
Reverb, double-tracking and stereo effects on the vocal aren't centred, so they survive cancellation. That's the limit of the technique; AI separation does better, at the cost of uploading the song.
Why didn't anything change?
The file is mono, or its channels are nearly identical — there's no centre to cancel. The status line checks this when you load the song.
What does the bass setting do?
Frequencies below it are kept from the original mix, because bass and kick sit in the centre too and would otherwise disappear with the vocal.
Is the song uploaded?
No — the processing is simple arithmetic on your device. Output is a mono WAV.
