Frequently Asked Questions
How does noise removal work?
It uses RNNoise, a recurrent neural network compiled to WebAssembly that separates voice from noise and attenuates the noise — all locally in your browser.
Does it work for music?
RNNoise is optimized for voice. On complex music tracks results may vary.
