The app that we are talking about is called WO Mic. It supports all three connectivity options, namely USB, WiFi, and Bluetooth, so I f your aged desktop computer does not have Bluetooth and WiFi, you can get the task done with the USB.
Using an Android Device as a Microphone
In order to accomplish the task, you will need to download the app on both your computer and your Android device. In the following guide, we will be demonstrating the app functionality over a WiFi connection on a Mac as the USB and Bluetooth ones are simple to use compared to the WiFi one.

Tap on “Transport” on the screen that follows to choose the transportation method.

Now launch the WO Mic app on your computer by double-clicking on its icon. If you use a Mac, click on Launchpad in your dock, and search for and click on “WO Mic Client.”
When the app launches, enter the IP address that you noted down above in the “Target IP address” input box. Leave both control port and media port with their default values as they are pre-configured. Checkmark the “Play in speaker” option to test the app functionality. Now click on “Connect.”
The app should immediately start working, and you should be able to hear the voice that goes into the microphone on your Android device. Should you wish to stop it, simply click on “Disconnect” on the computer client or tap on “Stop” in the device app.
