How to use this tool

How it works

Choose a PCM WAV file. Type is read from bytes.
Mark a noise-only region. The tool estimates that spectrum and attenuates matching bins.
Download a new WAV. This is a conventional spectral gate, not an AI denoiser.

Files stay in this tab. No upload.

The profile must cover at least one 2048-sample analysis window. Fluctuating noise may remain.

Supported inputs and outputs

PCM WAV in and out. Opus is gated until an encoder pack exists.

Example

Stationary hiss in the profile window loses energy; a 1 kHz voice-band tone is preserved more than the hiss.

Questions and answers

Is this AI voice isolation?

No. It is a spectral gate from a user-selected noise profile. Musical-noise artifacts can remain.
