My camera is the Replay HD1080. Great camera, but sound quality is somewhat lacking. One would think with today's technological advances, a camera could be built (and affordable) with good built-in sound quality. I had an external mic and played with various locations in the car prior to the Cresson event, but no matter where I put the mic, sound quality was poor at best. I even used a wind sock and had the mic out of the slip stream. I tried a new location for Cresson; under-dash, yet untested. But, as stated in an earlier post, I forgot to turn on the mic . . . next time. :willy_nilly:
