Test Microphone & Audio Input Instantly

Audio issues—such as quiet volume levels, background noise, robotic distortion, or complete silence—can ruin meetings, streams, and recordings. Testing your microphone beforehand ensures clear communication.

The Microphone Tester uses the Web Audio API to capture your audio feed securely in the browser, showing volume meters, real-time frequency analysis, and instant audio playback testing.

Key Features

  • Real-Time Volume & VU Meter: Monitor peak and average decibel levels to ensure your mic is not clipping or too quiet.
  • Frequency & Spectrum Visualizer: Watch real-time audio waveforms and frequency graphs to spot background hums or noise interference.
  • Instant Playback Recording: Record a short snippet and listen back immediately to judge clarity, echo, and noise suppression.
  • Audio Device Selector: Easily switch between different connected microphones, headsets, or USB interfaces.
  • 100% Private & Browser-Based: Audio is processed entirely on your local machine and is never uploaded or stored on any server.

Common Use Cases

  • Pre-Meeting Check: Verify your microphone is active and clear before joining Zoom, Teams, Google Meet, or Discord.
  • Troubleshooting Quiet Audio: Diagnose whether a microphone issue is hardware-related, an OS volume limit, or a browser permission problem.
  • Microphone Comparison: Test clarity differences between your built-in laptop microphone and an external headset or USB condenser mic.
