How it works

01

Start the mic

Click Start and allow microphone access when prompted.

02

Watch the meter

Speak normally — the level bar should move into the green and yellow.

03

Record & play back

Capture a short clip and listen to confirm how you actually sound.

What is an online microphone test?

An online microphone test shows whether your mic is capturing sound, at what level, and how you actually sound on playback. This page draws a live input meter, lets you switch devices, and records a short clip that never leaves the browser. Use it immediately before a meeting, voiceover, or screen recording so a muted input is not the first thing you notice after you stop.

How do I read the input meter?

Speak at the volume you will use in the real take. A usable signal sits in green to lower yellow, with occasional higher peaks. A flat bar means the wrong device, a mute switch, or a blocked permission. A bar pinned in the red means clipping — lower gain or move back. The meter proves arrival; the playback clip proves tone, hiss, and room echo.

Why is my mic silent in the browser but fine in Zoom?

Site permissions are per origin. Zoom can have access while this tab does not. Click the microphone icon in the address bar, choose Allow, and pick the same input Zoom uses. Also check that macOS Privacy → Microphone or Windows Privacy → Microphone includes the browser itself, not only the meeting app.

What should I do after the mic checks out?

If you only need a voice note, open the online audio recorder. If the next job is a product walkthrough, record screen plus microphone in ScreenBuddy, or grab a raw take with the online screen recorder. Generate captions later with the SRT & VTT subtitle generator or ScreenBuddy’s local transcription.

FAQ

Frequently Asked Questions

How do I know my microphone is working?
Start the test and speak at a normal volume. The live level meter should move and sit mostly in the green-to-yellow range. If it stays flat, your mic is muted, blocked, or a different input device is selected.
Is the microphone test private?
Yes. Your audio is processed entirely in your browser to draw the meter and the optional playback clip. Nothing is uploaded or saved to a server, and the recorded clip lives only in your browser until you leave the page.
Why is the level meter not moving?
Check that you allowed microphone permission, that the correct input is selected in the device list, and that your mic is not muted at the hardware or operating-system level. Closing other apps that may hold the mic can also help.
Can I record a test clip?
Yes. After starting the mic, click Record test clip, speak, then stop — an audio player appears so you can play it back and judge clarity, volume, and background noise.
Does this test system audio or only the microphone?
Only the microphone. Tab or system sound is a separate capture path. To include application audio with a screen recording, use the online screen recorder and enable Share audio in the browser picker.
Should I test the mic before a narrated demo?
Yes. A 10-second playback here is faster than discovering a silent take after a full walkthrough. When the meter looks healthy, record screen and microphone together in ScreenBuddy, or capture a quick browser clip first.

Record a walkthrough with clear narration

Narrate straight into ScreenBuddy, or add a voiceover per scene in the editor, and finish the product demo with brand titles, callouts, and captions transcribed on your own machine.
