How to use the phone’s microphone as a wireless microphone?

Most regular users don’t need a microphone, but sometimes we need a microphone to do things like make a video call on Skype or record our own voice. 

Most laptops are equipped with a microphone, but the quality is not so good, on the other hand, buying a good microphone will cost you a lot of money, which may not be justified for a regular user. In this case, the best option you have is to use a microphone that is embedded in your smartphone and is almost good quality. But how can we use our smartphone’s microphone?

In this article we will learn how to do this.

There are several ways to do this, most of which are complex and complicated. But in this article we will be using an application software called wo Mic.

What this app does is turn the phone into a microphone. In fact, the wo mic will record your voice and deliver it to the wo mic Client running on your computer to record it and then provide the audio file with a virtual microphone for the applications to use.

Information that can be accessed by the destination application via a virtual microphone.

In fact, an application assumes that you have a real microphone installed on your system. You can use this method to transfer audio information to applications similar to the sound recorder. The program lets you establish voice connectivity between your phone and computer in three ways: WiFi, Bluetooth, USB cable and WiFi Direct.


As a first step, download the wo Mic application from Google Play and install it on your Android phone. Next you need to install wo Mic Client on your computer. The client version for Windows, Ubuntu, and Mac operating systems is as follows:

OSX version

Windows version

Ubuntu 64-bit (16.04.1 LTS)

If you are using Windows you will need to install the corresponding emulator on your system. To do this, click on the wo_mic_driver_signed.exe link and install it.

If you are using Linux, run the following command on the Ubuntu distribution.

$ sudo modprobe snd-aloop

How to connect

As mentioned, connectivity is possible via Bluetooth, WiFi and USB. The easiest way is to connect via USB. To connect via USB you first need to enable the Usb debugging feature from the Developer section on your phone.

Once activated, connect the phone to a computer with a USB cable and run Wo Mic. Go to the Settings app and set Transport to USB. (Of course this option is selected by default.)

Go to the app’s home screen and touch start. Run the Wo mic Client on your computer, go to the Connection tab, select Connect and select USB.

Return to the home screen and select Play in speaker in the Options tab. The microphone can now be used. It should be noted that Bluetooth connectivity is the same way. This way you should select the Bluetooth option on your phone and computer.

Of course,

you should have a Bluetooth dongle on your PC or turn on a Bluetooth laptop.

WiFi connection requires more work. In the above method, first put Transport on Wi-Fi mode on Android phone and click on Start button on home screen. In this case, an IP address will appear at the top of the microphone icon. Note the address above. In the client application on your computer, select the Wi-Fi option and enter the IP address you see in the application into the field.

As in the previous case, you can use the microphone on your phone by selecting Play in speaker. To disconnect the microphone you can use the Disconnect button on your PC or the Stop button on your Android phone.

On the Ubuntu Linux operating system, run the following command to connect to the client via Wi-Fi.

$ sudo ./micclient-ubuntu-x86_64 -t Wifi

Also use the following command to connect via Bluetooth.

$ sudo ./micclient-ubuntu-x86_64 -t Bluetooth xx: xx: xx: xx: xx: xx

Also use the following command to record.

$ arecord -c 1 -r 48000 -f S16_LE -D “hw: CARD = Loopback, DEV = 1, SUBDEV = 0” foo.wav

It’s worth noting that the quality of the phone’s microphone is not as good as the expensive microphones, and if the ambient noise around you is high, it will have an adverse effect on sound quality. However, with the successful Wo mic app, you can use your phone’s microphone to record audio at no cost.
