How it works
How do you test your microphone?
Press Start and allow the microphone when your browser asks. Say a sentence at your normal volume: the meter moves with your voice and the result says whether the mic is working. Then record 5 seconds and play it back to hear yourself.
- 1
Allow the microphone
Press Start. Your browser asks once for permission, and the sound stays in this page.
- 2
Speak normally
The meter follows your voice. It should reach well into the right half when you talk, without hitting the end. Pick another mic from the list to compare.
- 3
Hear yourself
Record 5 seconds and play it back to hear what people hear on a call.
Why is my microphone not working?
Usually it’s muted, the wrong input is chosen, or the browser or computer hasn’t been allowed to use it. Check the mute switch, pick the right mic in your sound settings and allow it for your browser, then try again.

How do you check your mic on a Mac?
Open System Settings → Sound → Input and choose your microphone. The input level moves as you talk, and the Input volume slider sets how loud it is. Or run this mic check in Safari or Chrome to see the level and hear a recording.
- 1
Choose the input
System Settings → Sound → Input lists every microphone; select the one you’ll use.

- 4
Allow your apps
System Settings → Privacy & Security → Microphone lists the apps that may use it; turn on your browser and your call app.
Is this online mic test private?
Yes. It runs in your browser with the browser’s own audio tools. Your voice isn’t uploaded or sent to a speech service, and the 5-second recording stays in the page until you close it.
Can NoteOwl record meetings with this microphone?
Yes. NoteOwl records your microphone and your Mac’s own audio, so it takes meeting notes without a bot in Zoom, Teams or Meet, then writes the transcript with every speaker labelled, a summary and action items on your Mac. Dictation into any app is free.
FAQ
Questions about testing a microphone
How do I test my microphone online?
Open NoteOwl’s free mic test, press Start and allow the microphone. Say a sentence: the level meter moves with your voice and the result says whether the microphone is working. Then record 5 seconds and play it back to hear how you sound.
Does the microphone test work on an iPhone or Android phone?
Yes. NoteOwl’s microphone test works in Safari on an iPhone or iPad and in Chrome on Android. Tap Start and allow the microphone; a phone usually lists its built-in microphone plus any headset you connect.
Why can’t the microphone test hear me?
When NoteOwl’s microphone test hears nothing, the microphone is usually muted, the wrong input is chosen or the input volume is at zero. Check any mute switch or key, choose the right microphone in the list, and raise the input volume in your sound settings.
How do I let my browser use the microphone?
When NoteOwl’s microphone test asks, choose Allow. If you blocked it before, click the icon at the left of the address bar, set Microphone to Allow and reload the page. In Safari on a Mac, use Safari → Settings for This Website; on an iPhone, the Settings app, under Safari → Microphone.
Is my voice recorded or uploaded?
NoteOwl’s microphone test sends nothing anywhere. The level meter reads your microphone inside the browser, and the optional 5-second recording is kept in the page’s memory so you can play it back; closing the page deletes it.
What is a good microphone level?
In NoteOwl’s microphone test, your voice should push the meter well into the right half when you speak normally, without reaching the end. Reaching the end means clipping, which distorts your voice; a meter that barely moves means the input is too quiet for clear calls.
Can I check the microphone I use for Zoom or Teams?
Yes. Choose the same microphone in NoteOwl’s microphone test that you use in Zoom, Teams or Google Meet, speak, and play back the recording. The test turns off the browser’s echo and noise filters, so you hear the microphone as it really is.
