HARQ ClearVoice vs Noise Blocker

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.

Noise Blocker is a Windows app that reduces unwanted microphone sounds in real time, including fan noise, keyboard sounds, clicks, hiss, and room noise. Version 3 uses AI to distinguish a speaker’s voice from background sound and is designed for everyday laptops. The maker says the app needs no tuning or complicated setup. It is listed as compatible with Zoom, Google Meet, Discord, Slack, Teams, and OBS, and supports microphone audio for recording and streaming. Noise Blocker supports Windows 10 and Windows 11; other operating systems are not currently supported. Processing adds about 80 milliseconds of latency, which varies by system. The free version provides 30 minutes of blocking per week without an email requirement. A Personal license is a one-time payment of $50 for one person on up to three PCs, with 12 months of updates and priority support, indefinite use of covered versions, and a 14-day money-back guarantee. A 30-day business trial for up to 20 employees or computers requires a request and approval; no card is required.
