How to test your microphone for WhatsApp calls and voice messages

WhatsApp’s help pages describe no test call or microphone test. The nearest check inside WhatsApp is listening to a voice message before you send it. For calls, check the microphone in your phone or computer settings, then compare with a short browser recording made with the same microphone.

Check my microphone for WhatsApp calls

Check my microphone for WhatsApp voice messages

MicProbe’s WhatsApp tests approximate microphone processing locally in your browser. They do not connect to WhatsApp, send a message or measure what the other person hears.

Listen to a voice message before you send it

On a phone, tap and hold Microphone next to the text field, then slide up to lock hands-free recording. On a computer, click Microphone.
Speak a few sentences at your usual distance from the microphone.
Tap or click Pause, then Play to listen.
Delete the draft if it sounds wrong, or send it. On a phone, tapping Microphone again continues the same recording.

If the first word is cut off, WhatsApp suggests waiting a second before you start speaking. See WhatsApp’s guide to listening to voice message drafts.

Check your microphone before a WhatsApp call

WhatsApp advises testing the microphone and speakers in your device’s sound settings. On Windows, open Settings → System → Sound, choose the microphone under Input and select Start test. On a Mac, open System Settings → Sound → Input and watch the input level while you speak. On a phone, a voice message draft is the quickest check.

WhatsApp recommends a headset for the best call audio and notes that a separate microphone and speaker can cause echo. On supported Android phones, a one-to-one voice call also offers Noise cancellation. The WhatsApp desktop app hears only the left channel of a stereo input, so a microphone on an audio interface’s second input may not be heard; plug it into the first input.

Compare with a browser recording

Open MicProbe and select the WhatsApp call test or the WhatsApp voice message test, then choose the same microphone you use in WhatsApp. Follow the recording guide, then use Play to hear the saved sample. Keep your speaking distance, room and listening device the same for both checks.

A named MicProbe test is a local approximation, not a recording from WhatsApp. The voice message test follows voice messages from WhatsApp’s desktop and web apps; the phone app may record differently. On a computer, the call test also limits the sound to the range a WhatsApp call carries, so it can sound less bright than a plain recording.

What does the difference tell you?

Both recordings sound wrong: start with the microphone, its position and the room. Follow the guides for low volume, muffled speech or static and buzzing.
The browser recording is clear, but WhatsApp calls sound worse: check which microphone WhatsApp uses and try a headset. Then read why a clear recording can sound worse in a call.
Words go missing in calls: use the cutting-out microphone guide to separate missing words in your recording from interruptions in the call.

If WhatsApp cannot hear your microphone

Check the microphone permission first. On Android, open Settings → Apps → WhatsApp → Permissions and allow Microphone. On iPhone, open Settings → Privacy & Security → Microphone and turn on WhatsApp. On Windows, open Settings → Privacy & security → Microphone and turn on Let desktop apps access your microphone; on a Mac, use System Settings → Privacy & Security → Microphone. In WhatsApp Web, allow the microphone for web.whatsapp.com in your browser.

For calls, WhatsApp also suggests turning its permissions off and on again, making sure no other app is using the microphone, not using a virtual audio device, and turning off battery saver and Bluetooth. Read WhatsApp’s guide for calls that do not work. If voice messages will not record, WhatsApp’s voice message troubleshooting guide also covers the proximity sensor, Bluetooth pairing and storage space.

If you use a Bluetooth headset, sound playing through it can change when its microphone is active; see the Bluetooth microphone guide.

Common questions

Does WhatsApp have a mic test?

Its help pages describe no test call or microphone test. Recording a voice message, pausing it and playing it back before you send it is the nearest check inside WhatsApp.

Why does my voice sound different in a call than in a voice message?

A call is sent live and can change with the connection. A voice message is recorded first and sent as a file, so a weak connection delays it instead of cutting words out. Compare both on the same microphone to see which one changes.

Does MicProbe test WhatsApp’s servers?

No. Its WhatsApp tests use a local approximation. The connection check sends a sample voice to a nearby Cloudflare server and back, not through WhatsApp’s servers. Read what MicProbe measures and what it cannot check.

For other apps, see the Telegram, Discord and Zoom mic test guides.
