Noise Blocker
Netherlands
What it is
Noise Blocker removes background sounds from microphone audio in real time, including fans, keyboards, clicks, hiss, and room noise. Version 3 uses AI to separate a speaker’s voice from unwanted sound and is designed for everyday laptops. The maker says the app works without tuning or complicated setup. It is compatible with Zoom, Google Meet, Discord, Slack, Teams, and OBS, and supports microphone audio for recording and streaming. Noise Blocker runs on Windows 10 and Windows 11; other operating systems are not currently supported. Audio processing adds about 80 milliseconds of latency, which can vary by system. The free version provides 30 minutes of noise blocking per week without requiring an email address. A Personal license costs $50, paid once and covers one person on up to three PCs, with 12 months of updates and priority support. A business trial is listed as free for 30 days, for up to 20 employees or computers, subject to request and approval; no card is required and there is no automatic charge.
