Almost all desktop PCs don’t have a built-in microphone for recording. You will need to pair one via Bluetooth or wire in through the mic jack in order to get one to work on your PC for Skype or voice recording. Since most of us already have a smartphone with us, one that can be used as a high quality microphone, there must be a way to use our smartphones as a wireless microphone on our Windows computers.
Sure it is. Here are the ways, apps, and workarounds to make that happen.
If you have an Android phone
WO Mic is all you need. It turns your Android phone to be a wired or wireless microphone for your Windows system. Once connected, you can use it for voice chatting, recording, recognition, or Skype right on your PC with your Android phone hold in your hand. It supports 3 types of connections between your PC and phone: Bluetooth, USB, and WiFi.
To get it to work, aside the WO Mic app from Google Play store, you also need to install the PC Client and PC driver on your Windows system. USB connection is the most reliable method but if you like pacing around during the call, going with WiFi or Bluetooth should be your choice. You can adjust the connection type in Settings in Android app and Connection tab in PC Client.
It works almost flawlessly and responsively. It has nearly unnoticeable lag, just like REAL microphone devices.
If you are on iPhone
PocketAudio is probably one that works the best. It lets you use your iOS device as a wireless sound card of your computer. PocketAudio automatically forwards audio captured or played on your computer to your iOS device. You can use PocketAudio as a wireless headphones and/or wireless microphone for your computer.
You will need to install a client called PocketControl on your PC to act like a server application to receive the connection call from your iPhone. It only supports WiFi connection so far and no Bluetooth capability.
It works very well but the only catch is that the iPhone app costs $2.99US to have. If you are a frequent user, it’s actually quite cheap for having an app that turns your iPhone into a wireless microphone for your PC.
If you are using a Windows Phone
Same as iPhone users, PocketAudio is also your best chance. And again, the app costs another $2.99US.
However, if you are a Free-App kind of guy, Real Microphone for Windows Phone and Megaphone Free for iOS should do the tricks for you but you will have to give up the wireless mobility to exchange for the free option because both apps require a male-2-male headphone jack to hook your phone to the PC.
