Common questions
The Kleervox microphone isn't showing up in Zoom, Meet, or Teams
Open your call app's audio settings and choose the Kleervox microphone as the input device — on macOS and Linux it's "Kleervox Microphone", and on Windows it's "CABLE Output (VB-Audio Virtual Cable)". If you only just installed it, use the Restart button in Kleervox's setup (or fully quit and reopen the call app) so it re-scans for microphones.
I can't hear anyone on a call after setting up the microphone
Installing a virtual microphone can make your computer switch its speaker to that virtual device, so call audio plays into it instead of your real speakers. Open your system Sound settings and choose your real speakers or headphones as the output device. Kleervox detects this and shows a warning with a one-click "Open sound settings" button.
Does running Kleervox change the microphone in my other apps?
Only while it's actively cleaning. When Kleervox is signed in and running, it sets its virtual microphone as your system default so call apps work with no setup; when it's idle, closed, or signed out, it hands the default back to your real microphone — so other apps like your browser are never left on a silent input. You can always pick a specific microphone inside any app.
How do I set up the virtual microphone on Windows or macOS?
Open Kleervox and click "Set up microphone" — it walks you through it step by step. On Windows it guides you to install VB-Audio's free VB-CABLE (download → extract → right-click "Run as administrator" → Install Driver). On macOS it installs Kleervox's own microphone with one click and a single password prompt. On Linux the virtual microphone is created automatically — nothing to install.
I've used up my free time for today
The Free plan includes one hour of cleaning per day, measured in your local timezone and resetting at midnight. Until then your microphone keeps working — just without cancellation. Upgrade to Pro for unlimited daily use.
The other person can hear their own voice (echo)
Keep echo cancellation turned on in the Kleervox app. On laptop speakers it is a clear, audible reduction rather than perfect silence; using headphones removes acoustic echo entirely.
How do I cancel or change my plan?
Everything is in your dashboard. Cancelling keeps Pro active until the end of the period you have already paid for, then your account reverts to Free automatically. See the Refunds & Cancellation policy for details.
Is my audio private?
Yes. Noise and echo cancellation run entirely on your device. Your microphone audio, recordings, and the cleaned output are never uploaded, stored, or inspected by us.
Which operating systems are supported?
Kleervox runs on Linux, macOS 12 and later, and Windows 10/11.
