Mic test see and hear your microphone
Check before the call that your microphone works, that the right one is selected and how you sound. The test runs on this page. Your voice is not uploaded.
Press Start and allow the microphone when the browser asks.
Hear how you sound
Record 5 seconds and play them back. The recording stays in this tab and is gone when you close it.
How to read the result
- The bar moves when you talk: the microphone works. Normal speech should reach about the middle of the bar.
- The bar stays empty: the wrong input is selected, the microphone is muted, or the computer does not let the browser use it.
- The bar is always full: the input volume is too high and your voice will sound distorted. Lower it or move back.
- The bar moves while you are silent: the microphone picks up a fan, a keyboard or the room. Move it closer to your mouth and lower the input volume.
On a Mac
Open System Settings > Sound > Input to pick the microphone and set its input volume. If the browser gets no sound at all, open System Settings > Privacy & Security > Microphone and switch the browser on.
The microphone is fine but the call itself is hard to hear? See Zoom call volume too low on Mac. Want to check the other direction? Run the sound test for your speakers or headphones.
SoundDial for Mac
Your mic works. Now hear the call.
When a call starts, SoundDial lowers your music and the other apps and brings them back when the call ends. It gives each app its own slider, mute and equalizer, and it does not read or record your microphone. Try it here with three example apps.
Interactive demo with example sounds, running in your browser. The real SoundDial controls the apps on your Mac.
FAQ
How do I test my microphone?
Press Start mic test and allow the microphone when the browser asks. Then talk. If the level bar moves and the line wobbles while you speak, the microphone works. Record five seconds and play them back to hear how you sound to other people.
Why does the mic test not hear me?
Check three things. First, the browser: the microphone must be allowed for this page (the icon in the address bar). Second, the computer: on a Mac, open System Settings > Privacy & Security > Microphone and switch your browser on. Third, the input: pick the right microphone in the Input menu here, and look for a mute switch on the headset or its cable.
Why is my microphone so quiet?
On a Mac, open System Settings > Sound > Input, select the microphone and raise the Input volume slider. Then move closer: a laptop microphone at arm's length picks up far less than a headset next to your mouth. If the bar here barely moves while you speak normally, other people will find you quiet too.
Why do my Bluetooth headphones sound worse while the mic is on?
Bluetooth headsets switch to a call mode when their microphone is in use. That mode carries sound in both directions but at a much lower quality, so music sounds dull and flat until the microphone is released. Pressing Stop test here gives the microphone back. To keep music quality during a call, use the computer's own microphone as the input.
Is my voice recorded or uploaded?
No. The level meter and the recording run inside this browser tab. Nothing is sent to a server, and the recording is gone when you close or reload the page.
