Question 1

Is my voice recording uploaded anywhere?

Accepted Answer

No. The microphone audio is captured and encoded entirely in your browser using the MediaRecorder API. The recording never leaves your device unless you choose to download it.

Question 2

What audio formats can I export?

Accepted Answer

The recorder captures in WebM (Opus) by default, which most modern browsers and players support. The tool also offers a WAV export option for maximum compatibility with audio editors and DAWs.

Question 3

Why does the browser ask for microphone permission?

Accepted Answer

All browsers require explicit user consent before a website can access the microphone. Click Allow when prompted — the permission only applies to this page.

Question 4

Why does recording fail on some browsers?

Accepted Answer

Microphone access requires HTTPS (or localhost). If you are on HTTP, the API is blocked. Some older browsers also lack MediaRecorder support — use a current version of Chrome, Firefox, Edge or Safari.
