WHAT WE MAKE

One page that shows the full signal path

Most mic checks are a green dot that tells you nothing. Teste Microfone is amicrophone tester for everyone — job interviews on Meet, classes on Zoom, streams, podcasts, gaming, or a quick headphone check before a call.

Prefer to start right away? Run the free mic testor follow the 3-step guide.

  • Works on Windows, macOS, Android and iPhone — no install.
  • Auto-detects when you plug in a USB headset.
  • Honest status: live only when your mic truly is.

  • Live waveform

    See dropouts, silence and clipping the instant they happen — not after the call.

  • Level meter + peak hold

    Dial gain to the 40–75% sweet spot for clear, distortion-free calls.

  • Device picker

    Switch between headphones, webcam, laptop and phone mics without reloading.

  • Recorder + playback

    Record a clip and hear exactly how others hear you — echo, noise and all.

WHO IT'S FOR

Built for the moment before it matters

One link you can run beforehand — so “can you hear me?” never opens your meeting.

  • Interviews & meetings

    Meet, Zoom, Teams — verify device + levels first.

  • Teaching & classes

    Check laptop or headset mic before going live.

  • Streaming & gaming

    Catch Bluetooth thinness and gain jumps early.

  • Podcasts & voice

    Playback reveals room echo and mouth noise.

  • Support & troubleshooting

    Send one link instead of debugging over chat.

  • New devices

    Confirm a new headset, webcam or USB mic works.

OUR PRINCIPLES

Private by design. Free by architecture.

01 — PRIVATE

Local-only

Audio is analysed in your browser and discarded frame by frame. Recordings stay in your tab until you download or close it — there is no upload endpoint.

02 — FREE

No account, no paywall

Every feature is free and unlimited — no sign-up, no trial, no locked meters. Works on Windows, macOS, Android and iPhone.

03 — HONEST

Real signal, plain language

The status indicator shows live only when your mic truly is. A flat wave means something needs fixing — our guides show exactly how.

WHY WE BUILT IT

Because “can you hear me?” comes too late

Most mic checks happen 30 seconds into an important call. We wanted a one-link check you can run beforehand: allow, speak, record, play back — done in under a minute.

The companion fix guide andFAQ solve the common failures — blocked permission, wrong input, app locks, OS mute — without digging through forums.

HOW WE KEEP IT FREE

No audio servers, no costs to pass on

The tool is a static page — there are no audio servers to pay for because audio never leaves your device. That keeps costs low and privacy high by design.
