What Is a Mic Test?
A mic test lets you quickly verify that your microphone is working before a meeting, recording session, or gaming session. This free online microphone tester checks your audio input in real time, showing volume levels, a live waveform, and letting you record a short clip to play back.
Whether you're troubleshooting a USB condenser mic, checking your laptop's built-in microphone, or making sure your headset works before a video call, this tool gives you instant feedback without installing any software.
How to Use This Mic Test
1. Click Start Test and allow microphone access when your browser asks.
2. Speak into your mic and watch the volume meter and waveform respond.
3. Record a short test clip and play it back to hear how you sound.
4. Adjust your mic position or system volume until levels look good.
Key Features
Real-time audio level monitoring shows exactly how loud your mic is picking up sound. The live waveform visualization helps you spot issues like clipping, background noise, or dead silence. Record-and-playback lets you hear exactly what others will hear on the other end of a call.

Frequently Asked Questions
How do I test my microphone online?
Click the 'Start Test' button and grant microphone permission when prompted. The tool will instantly show your audio input level, a live waveform visualization, and let you record a short clip to play back and confirm your mic sounds clear.
Why is my microphone not detected?
Make sure your mic is plugged in and selected as the input device in your operating system's sound settings. Also check that your browser has permission to access the microphone — look for a camera/mic icon in the address bar and ensure it's set to 'Allow'.
Does this mic test work on mobile phones?
Yes — the tool works on iOS Safari and Android Chrome. Tap Start Test, allow microphone access, and you'll see your phone's built-in mic levels and waveform in real time.
Is my audio recorded or sent to a server?
No. Everything runs 100% in your browser. Audio data never leaves your device, and no recordings are stored or transmitted anywhere. Your privacy is fully protected.
Can I test an external USB or Bluetooth microphone?
Absolutely. Select your external mic as the default input device in your OS sound settings before starting the test, or use the device selector within the tool if available. The waveform and level meters will reflect whichever mic is active.
How do I fix a microphone that's too quiet?
First, check your system's input volume settings — on Windows, go to Settings > Sound > Input and increase the volume slider. On Mac, go to System Preferences > Sound > Input. If the mic is still quiet, move it closer to your mouth, check for any mute switches on the mic itself, and make sure the correct device is selected as your input.
How do I test my mic before a Zoom call?
Open this mic test tool before your call to verify your mic is working. You can also use Zoom's built-in audio test: in the Zoom app, go to Settings > Audio > Test Mic. However, our tool gives you more detailed feedback including waveform visualization and recording playback.
Does this work with Bluetooth headphones?
Yes. Connect your Bluetooth headphones and make sure they are set as the default input device in your system sound settings. Start the mic test and speak — the volume meter and waveform will show audio from your Bluetooth mic. If it doesn't work, try disconnecting and reconnecting the Bluetooth device.
Why does my mic test show no input?
The most common causes are: (1) browser permission not granted — look for a microphone icon in the address bar and click Allow, (2) wrong input device selected in system settings, (3) mic is muted via a physical switch or button, (4) another application is exclusively using the microphone. Try closing other apps that might be using the mic.
Can I test my webcam microphone?
Yes. Most webcams include a built-in microphone. Select your webcam as the input device in your system sound settings, then run the mic test. The tool will pick up audio from the webcam's mic and show it in the waveform and volume meter.
