Audio Check
A fast, two-step check of your microphone and speakers. ProbeCheck verifies audio input and output right in your browser — no uploads, no sign-ups, ready before your next call or recording.
Frequently Asked Questions
What does the audio check test?
It runs two quick checks in sequence: microphone (input level, sample rate, noise floor) and speaker (audio output and channel balance). Both use standard browser APIs and never upload your audio.
How long does the audio check take?
Typically under 5 seconds. Mic check runs first, then speaker check — you can skip either if you only need one.
Is my audio recorded or uploaded?
No. ProbeCheck measures audio levels locally on your device. No audio is recorded, uploaded, or stored. Results stay in your browser.
When should I use the audio check?
Before video calls, remote lessons, podcast recordings, or anytime you want to confirm your mic and speakers work. If you need network checks too, use Video Call Check instead.
