Online Mic Test

Click Start and allow microphone permission in your browser prompt. If you previously blocked it, use the lock icon in the address bar to allow access, then reload.

Make sure the correct input device is selected, your microphone is not muted, and no other app is using the microphone. On macOS/Windows, also check system microphone permissions for your browser.

Increase input gain in your system settings, move closer (10–15cm), and consider enabling noise suppression or disabling auto gain in Advanced.

Use the Microphone dropdown. If device names are hidden until you allow permission, click Start once to reveal real device labels.

No. This tool runs locally in your browser. Audio is not uploaded or stored. Recording files are created locally and only downloaded if you choose.

Yes, on modern Safari/iOS. If recording is unavailable, your browser may not support MediaRecorder. The live Microphone Test still works where microphone access is supported.

Bluetooth headsets may switch to “hands-free” mode which reduces quality. This is normal behavior. Try reconnecting Bluetooth and re-selecting the headset microphone as input.

Wear headphones. Loopback plays your microphone input through your speakers, which can cause echo or feedback.

Other apps can take exclusive control of the microphone or use a different selected device. Close other apps, re-check the app device settings, and re-run this test to confirm input.

Close other tabs/apps that might be using the microphone (Zoom, Meet, Discord), then Stop and Start again. On some systems, you may need to fully quit the app.
