Possible EVP

I have an audio file from our last hunt 01/04/12 it is a little long (sorry) but right after I ask "Do you know what your baby was?" I thought I heard a faint woman's voice say girl then my sister in-laws camera started up. I asked before that "what were you going to call your baby?" and then my brother in-law took a picture, you can hear the shutter (err!) anyway if someone can listen to it and see if they hear anything that would be great! There is also a strange noise in the background that get more intense when we talk about what we heard happened.
