Test your microphone before you start dictating.
Check that your microphone is working, see the signal it is actually sending, and get a practical quality readout before you dictate. Your browser does the test locally, so your recording stays on this device.

Sobre esta ferramenta
What this online microphone test checks
This microphone test listens to a short sample in your browser and shows the useful parts of the signal as they happen: a time-domain waveform for the shape of your voice and a frequency view for the low, middle and high parts of the sound. You can see whether the mic is hearing anything before you worry about the numbers.
After you stop, the test reports the microphone name when the browser makes it available, the input level, noise floor, clipping, sample rate, channel count, latency and the capture features your browser exposed. Device metadata varies by browser, so unavailable values are left honest rather than guessed.
Why your microphone matters for dictation
A microphone is the first link in dictation. Speech recognition can only work with the sound that reaches it: a distant mic, a noisy room or clipped consonants gives the model less to work with before any transcription software gets a say. A clean, consistent signal usually means fewer corrections and less time repeating yourself.
That does not mean the most expensive microphone wins. Placement, room noise and speaking clearly often matter more than the price tag. Use this test as a quick baseline: move closer, change the room or switch inputs, then run it again and compare the result on the same device.
How the quality rating works
The rating is a practical browser-side heuristic, not a studio certification. It combines whether a usable signal was present, how loud the speech was, how much room noise came through and whether the input clipped. A number is useful for comparing two setups; it is not a promise that every voice, room or dictation engine will behave the same way.
A moving waveform proves that sound exists, not that the sound is clear. That is why the result calls out noise and clipping separately, and why a quiet but clean microphone can still be more useful for dictation than a loud microphone that distorts.
Privado por design
The sample is recorded into your browser only so you can play it back. It is not uploaded, sent to a transcription service or stored by Yaps. Close the page and the local recording is released; you can also reset the test at any time.
The browser still has to ask for microphone permission. You can deny it, change the input in your browser or operating-system settings, and come back to run the test again whenever you like.
How to test your microphone online
Choose an input
Select the microphone you want to check. Some browsers hide device names until you grant permission, so the list may become more specific after the first test.
Permitir acesso ao microfone
Press Start microphone test and allow access when your browser asks. The sample stays in the page and is never uploaded.
Fale naturalmente
Say a few words at a normal dictation distance. Watch the waveform and frequency view move, then stop after a short sample.
Review the readout
Check the quality rating, signal level, noise floor, clipping, and technical microphone details. Use Test again after moving the mic or changing rooms.
Perguntas
How do I test my microphone online?
Choose an input if more than one is available, press Start microphone test, allow browser access, and speak for a few seconds. The page shows a live waveform and frequency view, then reports the microphone name, signal quality and technical details when you stop.
Does this microphone test record or upload my voice?
The browser makes a short local recording for playback, but the audio is not uploaded or sent to a transcription service. Resetting the test or closing the page releases the local recording URL.
What is a good microphone quality score?
A score above 80 usually means the test saw a useful signal with low noise and little clipping. The score is a browser-side heuristic rather than a studio measurement, so use it to compare setups rather than as an absolute guarantee of dictation accuracy.
Why is my microphone waveform flat?
The browser may not have permission, the microphone may be muted, another app may be using it, or the wrong input may be selected. Allow access, check the selected device, close other recording apps and run the test again.
Why does microphone quality matter for dictation?
Speech recognition can only interpret the audio that reaches the microphone. A clean, consistent signal gives it clearer consonants and less background noise to separate from your voice, which usually means fewer corrections and repeats.
Can I test different microphones?
Yes. Grant permission first so the browser can reveal device names, choose another input from the list, and run the test again. Comparing samples from the same room and speaking distance gives the most useful result.
