I Have 3-44 minute blocks of video to go along with everything but the last clip (leaving the area)
It recorded the first vocalization nicely as well as the wood knocks and rock clacking.I put it in a pouch so there is a little extraneous noise and the audio recorder was much more sensitive than the Ipad. I had to reset it every 44 minutes. The last time I tried to reset it it would even let me get past the lock screen so i missed the screams and the way out.
The only problem is I was using an IPAD set longways so the IPAD wouldn't fall out of the pouch I set it in. It looked ok on the IPAD but came out sideways on the video.
