Sobre esta ferramenta

Phone voice notes pick up air-con rumble and keyboard hiss. This cleaner applies a high-pass filter and a simple noise gate in your browser - the same idea as a cheap hardware gate, not a neural “AI studio”. It will not rescue a concert recording, but it can make a WhatsApp memo easier to hear. Pair it with the silence remover if you also want long gaps cut.

Como usar esta ferramenta

  1. Drop a voice memoShort notes work best. Processing uses the Web Audio API on your device.
