In their own words
Noise Blocker
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.
