OK, most of us turn our noses up at the audio from a simple sports camera, but the new Hero3 has surprisingly good audio now, compared to the older Hero2 and HeroHD. This series of tests is designed to find out just how great the GoPro Hero3's audio capabilities are. You'll hear the Hero3 in every possible audio situation from using the built in microphones to plugging external microphones in, and even a wireless setup.

Just thought I'd throw this out there.
