Question 1

How do I test if my microphone is working?

Accepted Answer

Click the Start button and allow microphone access. Speak normally and watch the volume meter — it should move as your voice is picked up. The frequency spectrum below shows which pitches are being detected. If the meter stays at 0, the mic is muted, blocked, or not selected.

Question 2

Is my audio sent to a server?

Accepted Answer

No. All audio processing — including the live volume meter, the spectrum visualization, and the recording — happens entirely in your browser. The audio stream never leaves your device unless you explicitly click Download.

Question 3

Can I record and save the audio?

Accepted Answer

Yes. Click Record to start, then Stop to finish. The recording is encoded to WebM/Opus using the MediaRecorder API and can be played back or downloaded with one click. Recording time is limited only by your available memory.

Question 4

Why does my browser block the microphone?

Accepted Answer

Modern browsers require HTTPS and explicit user permission for the microphone. The Microphone Test only works on https:// or http://localhost. If you previously blocked access, click the camera/mic icon in the address bar to reset the permission.
