Key Benefits & Capabilities
AI Spectral Gating
Analyzes the frequency spectrum of noise and attenuates it while preserving human speech clarity.
Custom Noise Profile Selection
Select a specific noise snippet on the waveform to train the denoiser on your exact room acoustics.
100% Client-Side Privacy
TensorFlow.js executes directly in your browser. Your private recordings are never sent to external servers.

Frequently Asked Questions
How does the AI noise reduction work?
It calculates a power spectrum profile of the background noise and applies frequency-selective attenuation across each FFT frame using overlap-add reconstruction.
How can I get the best noise removal results?
Highlight a 0.5 to 1-second segment of pure background noise (where no one is speaking) and choose 'Use current selection' in the Noise Reduction dialog.
