Online microphone test
Press Test my microphone, click Allow, and speak. If the volume bar moves and the waveform reacts, your mic works. It is fully online — no app, no signup — and the audio is processed locally and discarded the moment you stop.
Why test online?
- Nothing to download or install — it runs in any modern browser over HTTPS.
- Private: your audio is analysed locally with the Web Audio API and never uploaded.
