Audio Noise Remover uses your browser's built-in Web Audio API — no files are ever uploaded to a server. The tool applies a chain of standard audio processing nodes: a high-pass filter removes low-frequency rumble (e.g. air conditioning), a low-pass filter cuts high-frequency hiss, a dynamics compressor evens out volume levels, and a noise gate silences sections that fall below the threshold. The processed audio is exported as a lossless 16-bit WAV file.
