How to Use an Android Phone as a Microphone on Windows

Android phones are the most common spare microphone in the world. With a free app and a desktop client, the phone becomes a proper virtual microphone that any Windows application can use.

Install the app and client

Get WO Mic from the Play Store and the Windows client from the official site. Grant microphone permission to the app on first launch – Android 12+ also asks for nearby-device permission for discovery.

Connect over Wi-Fi

Put the phone and PC on the same network. In the app choose Wi-Fi and tap Start; the app displays its IP. In the client press Connect. If discovery fails, type the IP address manually – this also fixes most router-specific issues.

• Same subnet required
• Manual IP entry bypasses discovery problems
• 5 GHz Wi-Fi gives lower latency

Connect over USB

Enable Developer Options and USB debugging, connect the cable and accept the RSA prompt. Select USB in the app. This is the most stable mode and keeps the battery topped up during long meetings.

Android-specific fixes

Set the app's battery usage to Unrestricted, otherwise Android suspends it when the screen turns off. Disable 'Wi-Fi power saving' on Samsung devices, which throttles background network traffic. On Xiaomi and Huawei phones, lock the app in the recent-apps screen to prevent it from being killed.

Choosing the input in Windows apps

Select 'WO Mic Virtual Microphone' in the app you are using. In Windows Sound settings, set it as the default recording device and disable audio enhancements to avoid duplicate processing.
