Frequently Asked Questions
Common questions about removing background noise from audio files online.
What technology is used for noise removal?
This tool uses RNNoise, a recurrent neural network developed by Mozilla for real-time audio denoising. It's compiled to WebAssembly and runs entirely in your browser.
Is my audio uploaded to a server?
Never. RNNoise runs as WebAssembly in your browser. Your audio file never leaves your device — no upload, no server processing, completely private.
What types of noise can it remove?
RNNoise is effective at removing stationary background noise such as HVAC hum, fan noise, keyboard clicks, and general room noise. It works best on voice recordings.
Why is the output always WAV?
Audio denoising requires decoding to raw PCM, processing, and re-encoding. WAV is the lossless output format that preserves the full quality of the denoised audio.
