# Noise Reducer

> Free online AI tool by Inverse.AI that removes background noise from audio and video in about 30 seconds — no install, no sign-up to try. Trusted by 400k+ users (4.5★).

Noise Reducer removes background noise (wind, traffic, fan & AC hum, 50/60 Hz electrical hum, keyboard clicks, crowd chatter, echo, hiss and breaths) from both audio and video files, using a custom Mel-band neural network with a LoRA adaptation layer, while preserving natural speech. It also works as a voice cleaner, audio enhancer and volume booster, and includes a built-in noise-free recorder. Files are encrypted in transit, never shared, and auto-deleted within 24 hours.
