Microphone Test

Diagnostics should run locally without installing extra utilities. This microphone test page gives you microphone test without the clutter: verify your mic with a live input-level meter. Audio stays on your device — nothing is recorded or uploaded.

If the test fails

Check OS settings, tab mute, extensions, and whether another app has exclusive device access. Retry after a click if the browser blocked autoplay or permission prompts.

What Microphone Test checks

Verify your mic with a live input-level meter. Audio stays on your device — nothing is recorded or uploaded. Results describe this browser and device only — useful for isolating mute switches, permissions, and display quirks.

Where your data goes

Microphone Test runs in your browser for this job. Your microphone is not uploaded to FileToolsHub servers for the conversion itself, which matters when you are dealing with private notes, drafts, or local files.
