Yellow Brick Road, a Las Vegas classic rock cover band was doing a loud show outdoors on Fremont Street. I was within a few feet of the speakers. Click here for the video. I think I may have found the limits of audio recording (sound pressure levels) with the SEMA-1. I used a Church Audio battery box (9v power) and CAFS-Omni miniature stereo mics. It is possible that my battery was low on juice, and that was the cause of the audio issues, but I do think the camera is doing something to try and limit (cut) the audio. Overall, it's not that bad... better than any video recording setup I've had before, but I want better.
