What the neural filter can fix
The remover runs RNNoise, a neural network trained specifically to separate human speech from steady background noise: air conditioning and fan hum, computer noise, keyboard clatter, traffic and street ambience, room echo's low-level hiss. It shines on voice recordings — meetings, interviews, voice-overs, lecture recordings — where the noise sits under the speech. It is not a music tool: complex backgrounds like a band or a crowd singing are beyond any real-time noise filter.
Video in, video out
Drop in a video and the cleaned audio is put back under the original picture — the video stream itself is copied untouched, so nothing is re-encoded and the visual quality stays identical. Three strength levels let you trade aggressiveness against naturalness; start with medium and go stronger only if noise still peeks through in quiet moments.
