I record videos of my computer screen and put them on YouTube, I usually only record my voice and then have my friend on Skype. Soon my friend and I will be making a new video and this time we will both be @ my house, so I wanted to have both our voices in the video, so I bought these USB devices that have a microphone port on the other end so basically mic to USB. With these USB things I decided I could then plug them both into USB ports on my PC and have both our voices in the video, however my PC recognized the two microphones as different audio inputs so it only lets me choose one, so I tried using a 4 port USB extension cable but it still lists them as separate audio inputs.
So my main question is there any way I can possibly have both audio inputs inputting sound into my PC @ the same time, maybe there's a way I can merge both into just one audio input; please help me thanks,
EDIT: I am on Windows 7 and I have an Acer Aspire Laptop
