How can I get Hypercam to record audio and play along with the microphone?
I want to do a Lets Play with Hypercam, but I can not only choose between saving my microphone, and audio for gaming real. How do I record from both at once?
Hypercam is difficult to use and it is not so good for games record – but I recommend you try GameCam – it's free too virus-free if you get the shape of the actual site and audio and games much better than Hypercam. If not, try google-ing it or watch it on youtube. I hope it helped!
