    How to test your microphone

    1. Click "Start mic test" and allow microphone access.
    2. Pick your microphone from the drop-down if you have more than one.
    3. Talk at your normal volume and watch the meter and waveform.
    4. Press "Record 5s", then play the clip back to hear exactly what others hear.

    What is a good microphone level?

    Aim for peaks between −20 dB and −10 dB while speaking normally. Below −45 dB the other side will struggle to hear you: move closer or raise the input gain. If the meter keeps hitting the red zone near 0 dB, your voice will clip and sound harsh, so lower the gain or move the mic back a little.

    The "Dominant frequency" value shows the strongest pitch the mic picks up. Most voices sit between 85 Hz and 255 Hz. A constant reading at 50 Hz or 60 Hz with no one speaking usually points to electrical hum from a cable or power supply.

    Microphone not working? Try this

    • Browser permission: click the lock icon in the address bar → Microphone → Allow, then reload.
    • Windows 10/11: Settings → System → Sound → Input. Select your mic and check the "Input volume". Also open Settings → Privacy & security → Microphone and turn on access for desktop apps and your browser.
    • macOS: System Settings → Privacy & Security → Microphone → enable your browser. Then System Settings → Sound → Input to choose the device and input level.
    • iPhone / iPad: Settings → Safari (or Chrome) → Microphone → Allow.
    • Android: long-press the browser icon → App info → Permissions → Microphone → Allow.
    • Headsets: check the inline mute switch, and make sure the plug is in the mic (pink) jack or that you're using a 4-pole TRRS connector.
    • Bluetooth headsets: some switch to a low-quality "hands-free" mode when the mic is active. That is normal behavior, not a fault.

    Tips for clearer sound on calls

    • Keep the mic 10–20 cm (4–8 in) from your mouth and slightly off-axis to avoid pops.
    • Use "Hear myself" with headphones to monitor background noise in real time.
    • Soft furnishings such as curtains, rugs and a sofa reduce echo far more than any software filter.
    • Leave echo cancellation and noise suppression on for calls; turn them off only for music recording.

    Frequently asked questions

    How do I know if my microphone is working?

    Start the test and speak. If the level meter and waveform move with your voice and the status turns green, your mic works. Record a 5-second clip and play it back to confirm the quality.

    Can I use this as a quick mic check before a call?

    Yes. Open the page, press Start and say a few words. If the meter moves and the status turns green, your mic check is done. It takes about five seconds.

    Why is my mic so quiet?

    The input gain is probably low. Raise the input volume in your operating system's sound settings, move closer to the mic, and check that you selected the right device in the drop-down.

    Why does my microphone pick up an echo?

    Usually your speakers are feeding back into the mic. Use headphones, lower the speaker volume, and keep echo cancellation enabled in your calling app.

    Can I test a USB or Bluetooth microphone?

    Yes. Connect it, press Refresh in the device list if needed, and choose it from the microphone drop-down.

    Can I download my test recording?

    Yes. After recording, press Download to save the clip. It is created in your browser and never uploaded.
