For this particular piece I grabbed it off a video that my GoPro Silver took underwater. The GoPro had the standard waterproof housing it comes in. Actually I don't think there is a way to trim the input level of the onboard mic I'll have to research the GoPro's audio some more. It took some good 1080p underwater video.
Interesting sound. Did you record this when scuba diving? What mic and equipment did you use? - In fact, would be a good idea to put that in the description and tags, as I imagine that it would help people searching for this kind of sounds.
LOL he was talking about the fur on my microphone. Great windscreen, people always comment on it. This was one of those times, as I'm walking down the street recording sounds someone decides there going to make some noise for me. I've got hours of the most random stuff.
