Comprehensive Online Microphone Tester
Welcome to the most reliable way to test your mic online. Whether you are preparing for an important video conference, streaming, or recording audio, our free browser utility helps you verify that your microphone is capturing sound perfectly.
How to Check If Your Mic is Working
Simply click the "Request Microphone Access" button and speak normally. Our tool connects directly to your hardware and renders a real-time oscilloscope waveform. If you see the purple line spiking and rippling in response to your voice, your microphone is successfully picking up and transmitting audio.
Troubleshooting Common Microphone Issues
If the waveform remains a flat line while you are speaking, try the following steps:
- Check System Permissions: Ensure your operating system (Windows or macOS) has not globally muted microphone access for web browsers.
- Verify the Browser Prompt: Make sure you clicked "Allow" when the browser asked for permission to use your audio input.
- Hardware Connections: If using an external USB or 3.5mm headset, unplug it and plug it back in to force the PC to recognize the device.
