Frequently Asked Questions

How does vocal removal work?

This technique subtracts the center channel (where vocals are typically mixed) from stereo audio using phase inversion and mid-side processing.

Which file format should I choose?

WAV for maximum quality, WebM Opus for smaller file sizes. WebM requires browser support for MediaRecorder API.

Why are some vocals still audible?

Complete vocal removal is challenging. Results depend on the original mix, with center-panned vocals removing best. Reverb and backing vocals may remain.

How It Works

Audio is decoded using Web Audio API
Mid-side processing isolates and reduces center channel content
Optional normalization applies -1 dBFS peak limiting
Output encoded as WAV (manual RIFF writer) or WebM Opus (MediaRecorder)
