Device Tools · Local processing
Check live microphone level and waveform, then record and play a short local test clip.
Browser microphone permission required
The practical guide
The live meter, waveform, peak level, device label, and optional test clip are created with browser media APIs.
Speak at a normal distance and check that the level changes without remaining pinned at zero or maximum.
Playback helps reveal clipping, hum, echo, noise suppression, or the wrong selected microphone.
The clip uses WebM or OGG when supported. The tool does not pretend to create MP3.
Privacy by architecture
Audio tracks stop when you stop the test or leave the route. Clips are saved only when you choose Download.
Questions, answered
No. Metering, waveform drawing, recording, and playback happen locally.
Check browser permission, operating-system input settings, mute switches, and whether another app has the device.
Yes when the browser reveals multiple audio inputs after permission.
