Very awesome. Sound editing is something I'd like to learn as it can add a lot of awesomeness to a custom map, and other stuff as well. Unfortunately just don't have the time to experiment too much in it right now, as I spend that free time in other aspects of map creating. All these little touches add so much time to map development >.<. I dabbled in it for my comedy map on the arcade, "Plan H", and even that basic stuff took awhile to do.
I'm curious as to your hardware setup such a microphone and anything else for recording. Does it take a lot of expensive stuff to capture good audio?
