3. Select your microphone – Choose from the dropdown if you have multiple audio input devices.
4. Speak into your microphone – Talk at your normal volume level.
5. Watch the visualizer – Moving green bars confirm your microphone is capturing audio.

Before using our online microphone tester, ensure Windows audio is configured properly. Right-click the speaker icon in your taskbar > Sound settings. Under Input, verify your microphone is selected. When you speak, the volume bar should move.

If your microphone doesn't appear, check privacy settings. Go to Settings > Privacy & Security > Microphone (Windows 11) or Settings > Privacy > Microphone (Windows 10). Enable "Microphone access" and ensure your browser is allowed. USB microphones sometimes need driver updates—check Device Manager > Audio inputs and outputs.

Mac users should verify audio settings in System Preferences > Sound > Input. Select your microphone and speak—the input level meter should respond. No movement means macOS isn't receiving audio from that device.

When using our microphone tester, Safari or Chrome will request permission—click Allow. If you denied it previously, go to System Preferences > Security & Privacy > Privacy > Microphone and enable your browser. Newer macOS versions: System Settings > Privacy & Security > Microphone. Restart your browser after changing permissions.

Our microphone tester works on smartphones and tablets. Android users should use Chrome—open this page, tap the test button, and allow microphone access. The visualizer will respond to your voice immediately.

iPhone and iPad users should use Safari for best results. Tap "Check Microphone" and grant permission when prompted. If it doesn't work, verify Settings > Safari > Microphone is enabled.

External microphones work on mobile too. Connect your USB-C mic, Lightning adapter, or Bluetooth headset first. Your phone routes audio through external devices automatically—run our microphone tester to confirm.

Our microphone tester verifies hardware functionality. If your mic passes here, it works in all applications. However, each app has its own settings:

Zoom: Settings > Audio to select mic and test. Zoom's "Test Mic" feature lets you hear yourself.

Microsoft Teams: Profile > Settings > Devices for microphone selection and testing.

Discord: User Settings > Voice & Video for input device and sensitivity configuration.

Google Meet: Three-dot menu > Settings > Audio during a call.

Skype: Settings > Audio & Video, plus a test call feature.

OBS Studio: Settings > Audio > Mic/Auxiliary Audio for streaming/recording setups.

Our microphone tester uses the Web Audio API, native to all modern browsers. When you click the test button, MediaDevices.getUserMedia() requests microphone access. Once granted, your audio stream connects to an AnalyserNode that processes frequency and amplitude data. This data renders as the animated visualization you see.

Crucially, everything happens client-side. Your audio never travels to any server—we have no backend receiving microphone data. The entire process runs as JavaScript in your browser. When you leave this page, all audio processing stops. No recordings exist because nothing was ever recorded. This architecture provides accurate, real-time testing while guaranteeing complete privacy.
