Strange male voice , saying "i'm colder" no male was present with our group that night. 

While the 3 of us are talking, a fourth voice speaks up at the end.  The voice say's  "I didn't feel a thing"

As Carol and I  converse about the ground being soft, A voice adds their 2 cents also. It say's "Real Soft"

 You can here a loud noise,  We did not hear this noise @ our investigation only when reviewing the recordings.
