Check the signal before the important take

The microphone test opens the browser-selected input with automatic gain, echo cancellation, and browser noise suppression disabled where the browser supports those constraints.

Nothing is recorded or uploaded. The meter reads the live stream only while this page is open and stops the microphone tracks when you stop the test or leave.

Aim for a healthy normal-speaking level with headroom for louder words. Then make a short recording and listen back, because a level meter cannot reveal room echo, clothing noise, or plosives by itself.

Frequently asked questions

Does the microphone test record me?

No. It reads the live level only. Use the separate voice recorder when you want to capture and play back a test recording.

Why can I not see the microphone name before allowing access?

Browsers often hide device labels until permission is granted to protect privacy.

What level should speech reach?

Avoid peaks near 0 dBFS and leave room for louder words. The live guidance marks a moderate speaking range, but always listen to a short recording too.

How do I choose a different microphone?

Change the input in the browser or operating-system audio settings, then stop and restart the test.
