Microphone Test

Microphone test online — instant result

SpeakAndRecord's microphone test lets you instantly verify that your mic is working correctly in your browser. When you click "Test My Microphone," the browser requests permission to access your audio input. Once granted, the tool reads your mic's audio stream in real time and displays the waveform, decibel level, peak level, and technical device information — all without recording or storing anything.

The dB meter updates continuously as you speak, clap, or tap your microphone. The "Peak" indicator shows the highest level reached during the test session, which is useful for checking headroom before a recording. The device info panel shows which microphone the browser has selected, its sample rate, and whether echo cancellation is active.

If your microphone isn't producing any signal (the waveform is flat and the dB reads silence), the troubleshooting checklist provides the most common causes: browser permission issues, OS-level muting, wrong input device, or another application capturing the mic exclusively.
