Kleervox vs NoNoise Mac

Kleervox reduces background noise and speaker echo during calls using real-time processing on the device. Its neural noise cancellation separates speech from sounds such as keyboards, traffic, fans, and chatter, while echo cancellation reduces a caller’s voice leaking from speakers back into the microphone. It works as a virtual microphone in apps that let users select a microphone, including Zoom, Google Meet, Microsoft Teams, Discord, Slack, and OBS. The maker says microphone audio, recordings, and cleaned output are not uploaded, stored, or inspected. Its privacy policy also lists collection of Google sign-in details, usage metrics, installer activity, account state, sign-in history, website and demo analytics, and limited billing data. Free provides one hour of cancellation per day; afterward the microphone works without cancellation until local midnight. New accounts receive a seven-day Pro trial after first successful desktop use, with no card required. Downloads are available for Windows 10, Windows 11, and Linux; macOS is described as coming soon. Windows setup uses VB-CABLE, while Linux creates the virtual microphone automatically.

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 processing on the Apple Neural Engine and Metal. Meeting, Podcast, Tutorial, and Custom modes provide suppression and voice-polish controls. Optional Broadcast Voice adds presence and de-essing, while Mouth Noise targets plosives and clicks.

The app sends cleaned microphone audio through its NoNoise Mic virtual microphone for use in apps such as Zoom, Meet, Discord, OBS, Slack, and QuickTime. Clean Incoming / Guest can denoise system audio, but requires macOS 14.4 or later. The project says audio stays on the Mac, with no telemetry or account. It supports built-in, USB, and XLR microphones via an interface, along with global hotkeys and a bundled CLI for local audio-file cleanup. NoNoise Mac requires an Apple Silicon Mac such as M1 or newer; Intel Macs are not supported. Its installer is not notarized and may require approval in macOS Privacy & Security settings.
