Microphone Test
Free online microphone test. Check that your mic is working before calls, streams, or recordings with a live input level meter, real-time waveform visualizer, and device selection — all processed locally with nothing recorded or uploaded.
Device names appear after you grant microphone permission — until then they show as generic placeholders.
Check your microphone in seconds
Start the test and speak — you will see the live input level, waveform and frequency spectrum, and can record a short clip to verify playback quality.
The test runs entirely in your browser. Audio is processed locally and recordings never leave your device unless you download them yourself.
