Microphone Test (Input Level, Waveform, Frequency)
Display microphone input level (volume 0-100), waveform, and spectrum (80Hz-8kHz) in real time in the browser. Also supports input device switching, silence detection, and clip (potential distortion) detection.
Microphone Test (Volume, Waveform, Frequency)
Display volume level (0-100) / waveform / spectrum (80Hz-8kHz) in real time in the browser.

Volume Level (0-100)●Very low
0 /100
Guideline: During normal speech, levels around 40-70 are usually easy to work with (varies by environment).
Waveform (Oscilloscope)
Input over time
* The waveform shape changes with input. When near silence, changes may appear minimal.
Spectrum (Frequency: 80Hz-8kHz)
Focused on common voice frequency bands
* Low frequencies on the left, high frequencies on the right. High ambient noise may show activity across a wide range of frequencies.
What This Microphone Test Can Check
This page captures microphone input through the browser and displays volume level (0-100), waveform, and frequency spectrum. It is recommended for quickly checking whether input is coming through, whether it is too quiet, or whether it is clipping before a meeting, stream, or recording.
Frequently Asked Questions (FAQ)
Q. Permission dialog doesn't appear / I get an error
A. Check that microphone permission is allowed in your browser and that the input device is enabled in your OS settings.
Q. I'm making sound but nothing is responding
A. The wrong input device may be selected. Try switching the input device and also check the input volume in your OS settings.
Q. Values are extremely high / seems to be clipping
A. Lowering the OS input volume or increasing the distance from the microphone usually helps. Other applications' audio processing may also have an effect.
Note: This tool does not "measure" sound pressure (dB SPL) or audio quality. It is designed for checking whether input is coming through and whether it is too loud.
