Voice Isolation

Reduce background music and noise around speech — entirely in your browser.

This tool filters frequencies and compresses the level around the vocal band — it is not an AI track separation (like Lalal.ai). It works best when the voice is already the most prominent element in the mix; music heavily overlapping the voice will not be completely removed.

How it works?

Frequency filtering (vocal band), an FFT denoiser, and dynamic compression are chained via FFmpeg compiled to WebAssembly, directly in your browser. Nothing is sent to a server; only the engine (a static binary, not your data) is loaded on the first launch.
