Once installed Crystal Sound shows as a selectable microphone on lots of windows applications and browser apps. It works really well, my fans on my computer are a bit loud, but sitting next to the computer with a headset on and narrating into the mic on the headset it sounds like I am in a totally silent sound booth. Really have looked for a while like a product like this that just works. 5 tacos all the way, just wish I had bought more licenses, hopefully they have another appsumo deal.
