Microphone Test

Quick browser microphone check

What is the Microphone Test?

The Microphone Test uses your browser's Web Audio API to activate your microphone and display a live audio waveform. It confirms your microphone is connected, picking up sound correctly, and not muted — without needing to install any software.

How to Use

  1. 1Click "Start Test" and allow microphone access when the browser prompts
  2. 2Speak or make a sound near your microphone
  3. 3A waveform should appear moving with your voice
  4. 4If the waveform does not move, your microphone is not picking up audio

What is a Good Score?

A healthy microphone shows clear waveform movement when you speak and near-silence when you stop. A flat line when speaking indicates no signal — check your mute button, cable, or system audio settings.

Tips to Improve

  • If your mic is not detected, check that no other app (like a video call) has exclusive access to it
  • On Windows, check Settings > Privacy > Microphone to ensure browser access is permitted
  • Use this test before online calls to verify your mic is working before joining

Frequently Asked Questions
