Before joining a call, check both the speaker output and microphone input you intend to use. A browser recording is a useful first comparison, but finish with Zoom’s or Teams’ built-in test because each app can choose different devices and processing. This page does not connect to your meeting account.

A SIMPLE START
How to run this audio check
01
Check what you will hear
Connect your call headset and use the linked speaker test. Verify a comfortable playback level before checking the microphone.
02
Make a short voice recording
Choose your intended mic below, speak from your normal position, and play back five seconds. Check clarity and background noise.
03
Repeat inside the meeting app
Select the same devices in Zoom or Teams and use its built-in test where available. Check your mute state before joining the real call.
Test speaker and microphone audio in Zoom
Zoom provides speaker and microphone tests in its audio settings and during the meeting join flow. Use Test speaker and microphone when offered, listen to the output, then follow its microphone recording and playback prompts. You can also use Zoom’s test meeting to check the actual application path before an important call.
If the browser recording is clear but Zoom is not, compare the selected input and output names. Do not assume that connecting a USB headset updates every app automatically. Close the browser’s microphone capture after your comparison so you are not intentionally running two input checks at once.
Make a test call in Microsoft Teams
In the Teams desktop app, open Settings and more, then Settings and Devices. Under Audio settings, choose Make a test call when available and follow the test bot’s instructions. Microsoft documents this feature for the Windows and Mac desktop apps; the same option is not available in every Teams client or organization setup.
If you cannot find the test-call option, verify the chosen speaker and microphone in the available device settings and use the meeting’s pre-join controls. Your organization may manage some options. The browser check below is independent of Teams and does not confirm its account permissions or meeting-specific behavior.
A practical pre-call troubleshooting order
Begin with the physical mute switch and selected devices, then listen to a short voice clip. If the mic sounds distant, check whether the laptop or webcam microphone is selected instead of the headset. If playback echoes through a speakerphone, compare a headset setup and avoid running multiple audible copies of the call.
Keep the test representative: use the same room, headset, and normal speaking distance as the meeting. A quiet recording made close to a mic is not a useful prediction of a noisy call made across the room. Change one setting, repeat, and stop once speech is intelligible and stable.
FreeSoundTest is an independent utility, not a Zoom or Microsoft service. Its recording remains in browser memory, while tests performed inside those applications follow their own data practices. The platform documentation below is the source for their current menu paths and availability.

How do I test sound on Zoom before joining a call?+
Use Zoom’s speaker and microphone test when joining or open its audio settings beforehand. Listen to the speaker signal, then follow the microphone playback prompts. Choose the devices you will use in the meeting. A browser check can help first, but it does not configure Zoom’s own audio path.
How do I test sound on Microsoft Teams?+
In the supported Teams desktop app, open Settings and more, then Settings and Devices, and look for Make a test call under Audio settings. Follow the bot’s prompts. Availability depends on the client and organization. If it is unavailable, check the device selectors and pre-join controls instead.
Why does my microphone work here but not in a meeting?+
The meeting app can use a different input, permission setting, mute state, or processing configuration. Confirm the same device is selected in both places, and check a physical headset mute switch. Disconnect this browser test, then repeat the application’s own check to isolate its audio path.
Does this page send a recording to Zoom or Teams?+
No. The microphone check on this page runs locally and stores its short recording only in browser memory. It does not sign into, call, or send audio to either platform. If you run a separate test inside Zoom or Teams, that application’s terms and data practices apply.
