Mic Test & Voice Recorder
Turn on your microphone to confirm it works before a call, an interview or a recording session. A live waveform shows the signal shape while a meter reports the level in dBFS, coloured green when the level is healthy, amber when it is getting hot and red when it is close to clipping — so you can set your distance and gain before you record rather than discovering the problem afterwards. A peak reading holds the loudest moment since you started, which is the number to watch when you check whether a sudden laugh or a plosive will distort. If several microphones are connected you can switch between them, and the optional monitor lets you hear yourself through headphones. Recording captures directly to a file you can play back and download. Nothing is uploaded: the stream is handled entirely by your browser, the microphone is released as soon as you stop, and closing the tab discards every recording.
How to use
- Click Start microphone and allow microphone access when your browser asks.
- Speak normally and aim for a level that stays in the green, peaking in amber at most.
- Click Record to capture a clip, then play it back and download it if you want to keep it.
Frequently asked questions
- Is my audio uploaded or stored anywhere?
- No. The stream goes from your microphone to the page and no further — there is no server, no account and no storage. Recordings exist only as temporary objects in the tab, so closing it discards them. Stopping the microphone releases the device and turns off the browser's recording indicator.
- What level should I aim for?
- Keep normal speech in the green band, roughly −24 to −12 dBFS, with peaks reaching amber but not red. Digital audio has a hard ceiling at 0 dBFS: anything louder is clipped and the distortion cannot be repaired later. Leaving headroom is always safer than recording as loud as possible.
- The meter shows nothing when I speak.
- Check that the right input is selected in the microphone list, that your system input volume is not muted, and that a hardware mute switch on the headset or interface is not engaged. If the browser never asked for permission, re-enable the microphone for this site in the padlock menu in the address bar and reload.
- Why does the monitor cause a screech?
- That is feedback: the speakers play what the microphone hears, which the microphone then picks up again. Use headphones when monitoring, or leave the monitor off — the meter and waveform tell you everything you need without playing the sound back.
- What format is the recording?
- The browser picks the best format it supports, usually WebM with the Opus codec, or MP4/AAC on Safari. The file extension in the list tells you which one you got. Any of them plays in a modern browser and imports into common audio editors.
