Frequently Asked Questions

Find Quick Answers

Why isn't my microphone working with this tool?

Ensure you've granted microphone permissions in your browser. Check your system's audio settings to make sure the correct microphone is selected and not muted. Some browsers may block microphone access on non-HTTPS sites.

What information does this tool collect from my microphone?

The tool only processes audio data locally in your browser. No audio is transmitted to any server - all analysis happens client-side. We only display volume levels and frequency data for your reference.

Can I use this tool on mobile devices?

Yes, the tool is fully responsive and works on mobile browsers that support the Web Audio API. You may need to enable microphone permissions in your mobile browser settings.

What do the different colors in the visualization mean?

The visualization shows real-time audio input. Green indicates normal volume levels, yellow shows moderate volume, and red indicates loud audio that might cause distortion. The bars represent different frequency ranges of your audio.
