WO Mic lets you connect your smartphone as an external microphone through three primary connections: USB wired connection, Bluetooth wireless connection, WiFi wireless connection, and WiFi Direct wireless connection. The application is free to download and use and has low latency which means that you won’t experience a noticeable lag in your audio transmission.

Let’s get into the setup procedure:

The WO Mic application can be downloaded from the manufacturer’s website. For the purpose of this set up, you will need to download the PC client and PC driver on your computer’s end and the smartphone application on your mobile’s end.

Configuring A Wired USB Connection

The WO Mic Android Application’s Connect Interface.

Wired USB connection only applies to Android devices as Apple has locked USB communications for such applications on its lightning port. To perform the steps on an Android device, connect it to your PC using its USB cable and install any requisite drivers that your PC prompts you to install. If you regularly connect your smartphone to your PC, you may already have these drivers installed.

Head into the developer options of your Android device. Enable USB debugging here. By doing this, your PC will recognize your smartphone as an independent external hardware device (such as a microphone).

In the “Connect” window, click on “USB” in the left side bar and then click “OK.” Launch the WO Mic smartphone application on your Android device and click on the following: “settings cog” > “Transport” > “USB.” After doing this, you can head into the main application interface and tap on the play button to begin recording and using your phone as an external microphone on your PC.

Configuring A Wireless Bluetooth Connection

To connect your smartphone via Bluetooth, you will first need to turn on Bluetooth on both devices. This option can be toggled on Windows through its settings menu and on your smartphone through its respective settings interface as well. Once both devices are discoverable, enter them into pair mode and select the other device to pair. Follow the on screen instructions on your devices to do this.

Launch the WO Mic application on your PC and tap on “Bluetooth” in the left side bar in the “Connect” window. Select your smartphone from the drop down menu displayed and then click on “OK.” Head into the WO Mic smartphone application and click on the following: “settings cog” > “Transport” > “Bluetooth.” After doing this, you can head into the main application interface and tap on the play button to begin recording and using your phone as an external microphone on your PC.

Note that the Bluetooth connection works for both Android and iOS devices.

Configuring A Wireless WiFi Connection

To connect the two devices through a WiFi connection, you will first need to ensure that WiFi is turned on on both devices and that both devices are connected to the same Wireless network. Toggle these settings from the respective settings menus of both your PC and smartphone device.

Launch the WO Mic application on your PC and tap on “WiFi” in the left sidebar in the “Connect” window. Simultaneously, head into the WO Mic smartphone application and click on the following: “settings cog” > “Transport” > “WiFi.” Head back into the main interface and click on the play button.

Configuring A Wireless WiFi Direct Connection

To configure a WiFi-Direct connection between your smartphone and PC devices, switch on your smartphone’s WiFi hotspot. Ensure that you have an engaged cellular data connection or package in place before continuing. This method is usually used when your computer and device are unable to connect to a WiFi router and the USB and Bluetooth options are not feasible either.

Switch on your smartphone’s hotspot from its settings menu. Toggle your WiFi on your PC device and connect to your smartphone’s hotspot. Launch the WO Mic application on your PC and tap on “WiFi Direct” in the left side bar in the “Connect” window. Simultaneously, head into the WO Mic smartphone application and click on the following: “settings cog” > “Transport” > “WiFi Direct.” Head back into the main interface and click on the play button. Back in the WO Mic Windows application, ensure that the “Soft AP IP Address” is set to “192.168.43.1” and click “OK.” You can now use your smartphone to record audio on your PC.
