Microphone Test
Find out whether your microphone works and how loud it is before a call, a recording or a stream. Start the test and speak: a live meter shows the input level in dBFS with a peak hold, and the details list the device name, sample rate and processing settings. Record a 5-second sample and play it back to hear exactly what others will hear.

Features and Limitations
Features
- Live RMS level meter with a peak-hold marker and numeric dBFS readouts.
- Playback sample to check clarity, noise and distance.
- Shows device name, sample rate, channel count and whether processing is active.
- Microphone released on stop, reset or leaving the page.
Limitations
- Levels are relative to digital full scale (dBFS), not sound pressure in dB SPL; this is not a calibrated sound level meter.
- Browsers may still apply some processing on certain devices even with the raw option ticked.
- The sample format depends on your browser (WebM/Opus, OGG or M4A).
- Results are computed in your browser; nothing you enter is sent to a server.
Frequently Asked Questions
What level is good?
Normal speech should peak roughly between −20 and −6 dBFS. Constant peaks at 0 dBFS mean the input is too loud and will distort.
Why is the meter not moving?
The wrong microphone may be selected, it may be muted by a hardware switch, or another app may be using it. Try another device from the list.
Why does my voice sound different in the sample?
With the raw option ticked you hear the microphone without noise suppression. Untick it to hear what most call apps send.
Is my voice uploaded?
No. Everything stays in your browser.
