Frequently Asked Questions

Find Quick Answers

Does this tool work on all browsers?

The tool works on modern browsers that support Web Audio API and getUserMedia, including Chrome, Firefox, Edge, and Safari. You may need to grant microphone permissions when prompted.

Can I test multiple microphones?

Yes, if your computer has multiple audio input devices, you can select different microphones from the device dropdown menu to test each one individually.

Is my audio recording saved or uploaded?

No, all audio processing happens locally in your browser. Your recordings are not uploaded to any server unless you choose to download them. The tool works entirely client-side for privacy.

What do the visualizations show?

The waveform visualization shows amplitude over time, while the frequency spectrum shows which frequencies are present in your audio. Green/yellow indicates normal levels, red indicates clipping or distortion.

How can I improve my microphone quality based on the test?

If the test shows low volume, move closer to the microphone. If there's background noise, use a quieter environment. If frequencies are uneven, adjust microphone positioning. Clipping (red indicators) means your input is too loud - reduce gain or move further from the mic.
