NoNoise Mac is a free macOS menu-bar app that reduces microphone background noise and room echo in real time. It uses DeepFilterNet3 compiled to CoreML, with audio processed on Apple Neural Engine and Metal. Meeting, Podcast, Tutorial and Custom modes pair suppression with voice-polish controls. Optional Broadcast Voice adds presence and de-essing, while Mouth Noise offers plosive and click suppression. Clean Incoming / Guest can denoise system audio, but requires macOS 14.4 or later. The app routes cleaned microphone audio through its NoNoise Mic virtual microphone for use with apps including Zoom, Meet, Discord, OBS, Slack and QuickTime. It supports built-in, USB and XLR microphones through an interface, plus configurable global hotkeys, a URL scheme and a bundled command-line tool. The CLI can clean audio files locally. The project says audio stays on the Mac, with no telemetry or account. NoNoise Mac is open source under the MIT License and requires an Apple Silicon Mac such as M1 or newer; Intel Macs are not supported. Its installer is not notarized and may require allowing it in macOS Privacy & Security settings.
