HARQ ClearVoice vs NoNoise Mac

HARQ ClearVoice is paid workstation software for real-time microphone noise cancellation and accent neutralization during calls. It filters sounds such as traffic, barking dogs, and other agents before audio reaches a softphone. HARQ states that processing has 40 ms latency, runs on the CPU, and does not require a GPU. Audio remains on the workstation instead of being sent to a server, and the software can work offline. Accent neutralization is described as signal-level speech enhancement that preserves natural speech; it is not translation or text-to-speech. A virtual audio device outputs the processed signal, which the user selects as the softphone input. Named compatibility includes Talkdesk, Genesys, Five9, Avaya, and any SIP client using that device. ClearVoice is enabled as a toggle on an existing HARQ presence agent, without a separate installer. Auto-updates are included per device. Pricing is metered per device per month through an AWS Marketplace private offer, with rates supplied by sales.

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.
