Microphone Information
How to Use
Allow Microphone Access
Click 'Start Microphone Test' and allow the browser to access your microphone. For privacy, your audio never leaves your device.
Check the Visualizer
Speak or make sounds. If your microphone is working, you'll see the waveform or frequency bars moving in response to your voice.
Monitor Volume Level
The volume meter shows your input level. Green indicates normal levels, yellow means loud, and red indicates potential clipping.
Test with Recording
Record a short clip and play it back to check audio clarity. This helps identify background noise, echo, or quality issues.
Features
Real-time Visualizer
Choose between waveform (oscilloscope) or frequency spectrum display to see your audio signal in real-time.
Volume Level Meter
Color-coded volume indicator helps you identify if your mic is too quiet, optimal, or clipping (distorted).
Multiple Device Support
Switch between different microphones including built-in, USB, headset, and virtual audio devices.
Recording Playback
Record up to 60 seconds and play back immediately to check your voice quality, clarity, and any background noise.

Common Use Cases
Pre-Meeting Check
Test your microphone before Zoom, Teams, Discord, or Skype calls to ensure clear audio communication.
Streaming & Recording Setup
Streamers, podcasters, and content creators can verify mic quality and optimal input levels before going live.
Troubleshooting
Diagnose microphone problems by checking if the browser detects input, what levels are received, and if recording works.
New Hardware Testing
Quickly test a new USB microphone, headset, or audio interface to verify it's properly recognized and functioning.
Privacy & Security
This tool processes audio entirely in your browser using standard Web Audio APIs. No audio data is ever recorded on any server or transmitted over the network. You can verify this by using the tool offline or monitoring network traffic.
Tips
- Position your microphone 6-12 inches from your mouth for best results. Too close causes plosives, too far reduces clarity.
- Close other applications that might be using the microphone (Zoom, Discord, OBS) before testing.
- If volume is too low, check your operating system's microphone gain settings in Sound preferences.
- For USB microphones, try different USB ports if the device isn't detected or has issues.
- Use headphones when enabling audio monitoring to prevent feedback (howling) from speakers.
