A German-language browser tool that checks microphone input, displays live levels, lets you monitor yourself, and plays back a test recording.

Landing page captured for the 2026-09-02 issue.

Field notes

The tool reads the chosen microphone through the browser’s Web Audio interface and exposes both a live level meter and a short local recording workflow. Its guidance distinguishes no signal, very quiet input, a good range, and clipping, while noting that normal speech should generally land around 30–70%. The page also explains how browser permissions, competing applications, headset modes, and physical mute switches can prevent detection. It states that recordings remain in browser memory rather than being uploaded or permanently stored.
