In their own words
Kleervox
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.
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.
