How to use a USB Mic AND Mixer together in Skype or Vidblaster

Web cam software like Skype and Vidblaster only allow for one audio source, so if your mixer is coming into the computer via the line input, and your mic is coming in through USB, you are generally out of luck….until now.

I recently stumbled upon a free piece of software called Voicemeeter which makes it incredibly easy to solve this problem. It is basically a software mixer that will allow you to take various inputs as well as your system sound and mix them with a great deal of control into one “Virtual” sound device, which you can then select as your audio input device in your web cam program.

To get started, Download your free copy of Voicemeeter HERE.During installation, you will get some dialogue boxes telling you it wants to install some drivers, this is completely normal.

Once you have installed it, you will need to restart your computer so the virtual drivers can register in your system. Once you have rebooted, open up Voicemeeter and you will see the mixing console.

Looks cool doesn’t it! In short, you have two hardware inputs and one virtual input. The virtual input seems to be your system sound, so anything that tries to output through your computers speakers, like Winamp or Windows Media Player, can be fed into your mix here if you want it, if not, just mute this track by pressing the “M” button at the bottom next to its slider. To mix your Mic and Line In (Mixer) click where it says “1 Hardware Input” and select your USB Mic from the drop down list.

The next step is to select your line in/mixer device in “2 Hardware Input”

Now its time to tell Voicemeeter where your speakers are. Select them from the drop down menu that says “Hardware OUT”

The last step to making this all work is to open your Windows menu and select control panel. When this opens select the sound icon to open your computers sound preferences window. In the “Playback” section select “Voicemeeter Input” and then set it as the default device.

Now you are all configured, you just need to do a small adjustment in Voicemeeter to stop feedback loops. The output of Voicemeeter has two channels, “Main Out” which will go to your speakers, and “Virtual Out” which is what will go into web cam software (Skype, Vidblaster etc….)

   In the “1 Hardware Input” channel, it is wise to de-select “A” as this will stop your mic from being played out aloud through your speakers. This will prevent feedback, but still allows your USB Mic to feed into your web cam program through the Virtual Out.

Now, all that’s left is to open your web cam program, Skype or Vidblaster etc, and select Voicemeeters output as your input device, and you can now use your USB Mic AND your external hardware mixer.
