Tools / Webcam and mic test

Webcam and mic test

One press starts your camera and microphone, with one answer for both and a clip with sound to play back.

Free, no account, nothing uploaded. Works on a phone too. Updated October 17, 2026.

Input off
See and hear yourself hereSit where you stream, then start. Your camera and microphone stay off until you do.

Camera and microphone off. Start them, then choose Allow if your browser asks.

These readings describe the picture in this browser, not your OBS output.

More test controls

Start the camera to see the choices your browser allows.

Mirrored is how you see yourself in a mirror. Viewers see the picture unmirrored, as OBS receives it, unless you flip it there. Your snapshot matches this view.

Thirds lines help you place your eyes near the top line.

Record a test clip

Play the clip back to check picture and sound together, the way a viewer gets them.

Nothing is uploaded. The camera and microphone turn off when you stop them or leave this tab.

How to test your webcam and mic together

  1. Sit where you stream, with your normal light on, and press Start camera and microphone. Choose Allow for both if your browser asks.
  2. Talk at your normal level, then your loudest: a laugh or a shout. Move as you would on stream.
  3. Read the answer at the top of the results. It names the more serious of the two problems first, so you fix in the right order.
  4. Press Record 10 seconds with sound and play the clip back on headphones. Watch your lips against your words: if they drift apart, see fixing audio and video sync.

What the two halves check

The camera half reads the picture this browser receives: its size, how many frames reach the tab each second, and how bright it is, with a note on anything to fix first. The webcam test has the full set of camera tools: a framing grid, a snapshot, the largest mode the camera offers and two cameras side by side.

The microphone half reads your voice on OBS’s own meter zones: green below -20 dBFS, yellow from -20, red from -9. Speech should peak in the upper yellow and only touch the red on your loudest. It flags clipping, a quiet level, a loud room and silence, the same as the microphone test, which adds a 30-second history, a noise-gate suggestion and both stereo channels.

Both read what your system delivers before any app processes it, which is what OBS starts from. A call app such as Zoom, Teams or Discord then changes the sound and sometimes the picture; the sections below say how.

Camera or microphone not working? Pick your computer or app

The steps for the system you are on open first. Each section gives the camera steps, then the microphone steps; each app section also says what that app does to your picture and your voice.

On Windows 11 or 10

Camera

  1. Windows 11: open Start, Settings, Privacy & security, Camera. Windows 10: Start, Settings, Privacy, Camera.
  2. Turn on camera access for the device, for apps and for desktop apps (Windows 11 calls them Camera access, Let apps access your camera and Let desktop apps access your camera). Microsoft counts web browsers, OBS and Discord as desktop apps.
  3. Some laptops have a camera switch, a sliding cover or a key with a camera symbol that turns the camera off.
  4. Open the Windows Camera app. If the picture works there, the camera is fine and the problem is the browser or the app.

Microphone

  1. Check the mute switch or button on your microphone or headset.
  2. Windows 11: open Start, Settings, Privacy & security, Microphone. Windows 10: Start, Settings, Privacy, Microphone. Turn on Microphone access and Let desktop apps access your microphone. Web browsers and OBS are desktop apps.
  3. Open Settings, System, Sound. Under Input, choose the microphone you speak into.
  4. Select that microphone to open its properties, press Start test and speak (Windows 10: Test your microphone on the same page). If Windows hears nothing either, the problem is the connection or the device, not the browser. Adjust Input volume there if you are too quiet.

On a Mac

Camera

  1. Choose the Apple menu, then System Settings, Privacy & Security, Camera, and turn access on for your browser, OBS and any call app.
  2. In Safari, also choose Safari, Settings, Websites, Camera and allow this site.
  3. Photo Booth and FaceTime use the camera without asking, so they are a quick check of the camera itself.

Microphone

  1. Choose the Apple menu, then System Settings, Privacy & Security, Microphone, and turn access on for your browser and for OBS.
  2. Open System Settings, Sound, Input and select the microphone you speak into. Its level bar moves as you speak.
  3. Drag the input volume slider if you are too quiet or too loud, then test again here.

On a Chromebook

Camera

  1. Select the time at the bottom right, then Settings, Privacy and security, Privacy controls, and turn on Camera access. Off here blocks the camera for every app and site.
  2. Some Chromebooks have a physical camera switch or cover beside the lens: slide it open.
  3. On a school or work Chromebook the administrator may have turned the camera off, and only they can change it.

Microphone

  1. Select the time at the bottom right, then Settings, Privacy and security, Privacy controls, and turn on Microphone access. Off here blocks the microphone for every app and site.
  2. Choose the microphone under Settings, Device, Audio, Input, or from the arrow beside the volume in Quick Settings.
  3. Some Chromebooks have a physical microphone switch: make sure it is on.

On Linux

Camera

  1. Open a camera app such as GNOME’s Camera (Snapshot) or Cheese. If the picture works there, the camera and its driver are fine.
  2. In a terminal, v4l2-ctl --list-devices (from the v4l-utils package) lists every camera the system sees.
  3. A browser installed as a Snap or Flatpak can be blocked by that packaging system’s own permissions; a browser from your distribution’s own packages avoids that layer.

Microphone

  1. Open Settings, Sound, and choose the microphone under Input; its level bar moves as you speak.
  2. With PulseAudio or PipeWire, pavucontrol (PulseAudio Volume Control) shows every input on the Input Devices tab and which app is recording on the Recording tab.
  3. A browser installed as a Snap or Flatpak can be blocked by that packaging system’s own permissions; a browser from your distribution’s own packages avoids that layer.

On a phone or tablet

Camera

  1. Testing your phone’s camera works here too: open this page in Safari on an iPhone or iPad, or in Chrome on Android, and press Start camera and microphone. The camera list lets you switch between the front and back cameras.
  2. iPhone and iPad: Settings, Apps, Safari, Camera, then Ask or Allow (on older iOS versions, Settings, Safari, Camera).
  3. Android: in Chrome, tap the icon left of the address, then Permissions, Camera, or open Chrome’s menu, Settings, Site settings, Camera.
  4. Using the phone as your stream camera is a separate path; this test checks only that the phone’s browser sees the camera.

Microphone

  1. Testing your phone’s microphone works here too: open this page in Safari on an iPhone or iPad, or in Chrome on Android, and press Start camera and microphone.
  2. iPhone and iPad: Settings, Apps, Safari, Microphone, then Ask or Allow (on older iOS versions, Settings, Safari, Microphone).
  3. Android: in Chrome, tap the icon left of the address, then Permissions, Microphone.
  4. A phone browser usually turns on its own noise and echo processing, so a phone reading is a working check, not a level for OBS.

In the browser

Open this site’s permissions beside the address bar and allow Camera and Microphone, then press Start again. Close other apps and tabs that may be holding the camera or microphone, including OBS. The page needs a secure HTTPS connection, so open it in your usual browser rather than inside another app.

Works here, but not in OBS

Then your system is fine and OBS is pointed at the wrong device or another app holds it. Follow webcam not detected or black and microphone not showing up in OBS.

In OBS Studio

Camera

  1. In Sources, press +, add a Video Capture Device and choose your camera under Device.
  2. OBS changes nothing in the picture by itself: set Resolution/FPS Type to Custom to choose the size and frame rate this page measured, then add filters only if you want them.
  3. A black source usually means another app is holding the camera: close calls, the maker’s camera app and this page, then deactivate and reactivate the source.

Microphone

  1. Open Settings, Audio, and choose your microphone under Mic/Auxiliary Audio, or add an Audio Input Capture source to a scene.
  2. OBS sends your voice as the device delivers it: no automatic gain and no noise removal unless you add filters. That is why this page shows the unprocessed signal by default and why OBS’s meter zones match the meter above.
  3. Set the level at the microphone or interface first, then add a noise gate or noise suppression filter if the room needs it.

In Discord

Camera

  1. Open User Settings (the gear at the bottom left), Voice & Video, then the Camera list, and press Test Video.
  2. Discord can add a video background or blur behind you; the others in the call see it too.
  3. If the preview stays black, Discord suggests turning off Hardware Acceleration in the Advanced section of the same page.

Microphone

  1. Open User Settings (the gear at the bottom left), Voice & Video, and choose your microphone under Input Device. Let’s Check under Mic Test plays your voice back (desktop app and browser only).
  2. Discord can process your voice: Noise Suppression (Krisp), Echo Cancellation and Automatic Gain Control, plus an input sensitivity that cuts you off between words. If you sound choppy or pumping, turn them off one at a time.
  3. Discord’s own processing does not reach OBS. A stream that captures Discord hears your friends through Discord and you through OBS.

In Zoom

Camera

  1. In the desktop app, select your profile picture, Settings, then Video & effects: the preview shows the chosen camera, with a Camera list to switch.
  2. Zoom can change the picture before it is sent: Touch up my appearance softens the skin, Adjust for low light brightens a dim picture, and HD sends a sharper picture when it is ticked. Mirror my video preview flips only your own view.
  3. If Zoom shows the camera sideways, hover over the preview and press the rotate button until it is upright.

Microphone

  1. In the desktop app, select your profile picture, Settings, Audio. Choose the microphone and press Test microphone: Zoom records and plays back.
  2. By default Zoom removes background noise and cancels echo (Microphone modes, Background noise suppression: Auto, Low, Medium or High). Automatically adjust microphone volume rides your level for you and hides the manual slider. Original sound for musicians turns the noise suppression off.
  3. If Zoom does not list your microphone, the system permission above is usually off for Zoom.

In Microsoft Teams

Camera

  1. Select Settings and more (…), Settings, Devices, then choose the camera under Camera and check its preview.
  2. Teams can blur or replace the background, and its video effects can brighten or soften the picture: open them from the camera button’s menu in a meeting.
  3. Make a test call, on the same Devices page in the Windows and Mac apps, records a short message and plays it back with your video.

Microphone

  1. Select Settings and more (…), Settings, Devices, then choose the microphone under Audio settings.
  2. Noise suppression is on by default and suppresses background sound; Voice isolation also suppresses other people’s voices. Microsoft suggests turning it off for a high-quality microphone in a quiet room. Automatically adjust mic sensitivity rides your level.
  3. Make a test call on the same page records a short message and plays it back (Windows and Mac apps).

In Google Meet

Camera

  1. Open meet.google.com, choose Settings, then Video. Pick the camera; its picture appears beside the list.
  2. Send resolution sets what others receive: Full High Definition (1080p) only on computers with a 1080p camera and enough processing power, and only on some paid Google Workspace editions or Google One with 2 TB or more of storage; otherwise High Definition (720p) or Standard definition (360p). Google says 1080p is not offered in Firefox or Safari.
  3. If Meet shows no camera, check the browser’s camera permission beside the address bar first: Meet runs in the browser, so the browser steps above apply.

Microphone

  1. In Meet, choose More options, Settings, Audio, and pick the Microphone.
  2. Noise cancellation removes non-speech sounds such as typing or a door; it is on by default on many paid Google Workspace accounts and off on others. Turn it off if you need music or other sounds heard.
  3. Meet runs in the browser, so the browser permission beside the address bar decides whether it can hear you at all.

Menu paths checked October 9, 2026 to October 14, 2026 on each maker’s help pages.

Questions

Can I test my webcam and microphone at the same time?

Yes: press Start camera and microphone above. Both run together, the answer covers both, and the 10-second clip records the picture with your voice.

My microphone works here but nobody hears me in Zoom, Teams or Discord. Why?

Each app chooses its own microphone, separate from the computer’s default. Open the app’s audio settings (the sections above give the path) and pick the same microphone this page used.

Why does my voice sound different in a call than in the clip?

Call apps clean up the sound before sending it: noise suppression, echo cancellation and automatic gain. The clip here is recorded without that processing, which is closer to what OBS records.

Does this test work on a phone?

Yes. Open the page in Safari on an iPhone or iPad, or in Chrome on Android. The camera list switches between the front and back cameras. A phone browser often applies its own sound processing, so treat the microphone reading as a working check.

Is this webcam and mic test private?

Yes. The picture, the sound, the readings and the clip are made in your browser and never uploaded. This site counts only that a test ran, not what it saw or heard.
