Mic Test Online — Hear Yourself Live or Record & Play Back in Your Browser (No Upload)
Use headphones before turning this on, or the mic will pick up the speakers and howl.
Check your microphone in the browser before a meeting, a stream or a recording — no app, no sign-up. Press Start and allow the mic: the level meter and waveform move as you speak, and the status tells you whether sound is coming through, is too quiet, or is clipping. Pick a specific input device if you have several (headset, webcam, USB mic). Turn on "Hear yourself" to monitor your voice live through headphones, or record a 10-second test and hear it played straight back — the same way you'd sound on Zoom, Teams, Discord or Meet. Everything runs inside your browser; your audio is never uploaded, stored or sent anywhere, and the test recording is discarded when you leave the page.
A free online mic test that runs entirely in your browser — no app to install and no sign-up. Press Start, allow the microphone, and the level meter and waveform react in real time as you speak. The status tells you automatically whether sound is coming through, is too quiet, or is clipping, so you can tell at a glance that your mic is being picked up. If you have several inputs — a headset, a webcam, a USB mic — you can pick which device to test. Turn on "Hear yourself" for live monitoring through your headphones (use headphones, or the microphone will pick up your speakers and howl). If live monitoring is hard to judge, hit "Record 10s & play back": it records a ten-second clip and plays it right back so you can hear how you actually sound. Use it as a quick mic test before Zoom, Teams, Discord or Google Meet calls, before going live, or before a recording session. You can also turn off the browser's mic processing (noise suppression, echo cancellation, auto-gain) to check the raw, unprocessed sound. Everything happens inside your browser: your audio is never uploaded, stored or sent to a server, and the test recording is discarded when you leave the page. Works in browsers on Windows, Mac and phones.
How to use
- Tap "Start mic test" and choose Allow when the browser asks for microphone access.
- Speak into the mic and check that the level meter and waveform move and the status reads "Your microphone is working". If you have several mics, switch with "Input device".
- Put headphones on and turn on "Hear yourself", or press "Record 10s & play back" to listen to how you sound.
FAQ
How do I hear myself?
Two ways. (1) Put headphones on and turn on "Hear yourself (live playback)" — your voice is fed straight back to your ears. (2) Press "Record 10s & play back" to capture ten seconds and play it back automatically. For (1) you must use headphones or earphones; on speakers the mic picks up the playback and you get feedback howling.
Is my audio uploaded?
No. Capturing the mic, analysing the level and waveform, and the test recording and playback all happen entirely in your browser — nothing is uploaded, stored or sent to a server. The test recording is discarded when you leave the page.
Can I check how I'll sound on Zoom, Teams or Discord?
Yes — the browser receives audio from the same microphone, so this works as a pre-call mic test. Use "Record 10s & play back" to judge your volume, background noise and clarity. Note that calling apps apply their own noise processing, so it won't be an exact match for the call audio.
I have several microphones — can I choose which one to test?
Yes. Pick it under "Input device". Device names appear once you've allowed microphone access. Choosing a different one automatically reconnects to that microphone and continues the test.
What if no sound is detected?
First check that "Input device" is set to the mic you want. Then check for a physical mute switch on the mic or headset, and the microphone permission icon next to the address bar. On Windows 11 / 10, check Settings > Privacy & security > Microphone to confirm your browser is allowed; on macOS check System Settings > Privacy & Security > Microphone. Browser microphone access only works over a secure (https) connection.
It says the signal is clipping — what should I do?
Your input level is pinned at maximum and the waveform is being squared off. Lower the input volume in your OS sound settings (including any mic boost) or move slightly further from the mic. If it says the sound is very quiet instead, move closer or raise the input volume.
