About 3 sec in theres a strange sound like someone going hmmm.

Hi, iv heard quite a few of these before, and most of the time its the other person doing it but without noticing they are doing it, if that makes sense, it could be paranormal but to me it sounds like a woman "hhhmm" and it seems to connect very well to what you asked your friend, like i said i don't think this is deliberate and yes there is a possibility of paranormal, but i think its something that can be explained.

Keep up the good work

I must disagree with 2stilr... that 'hhhmmm' is said with much more lower voice than you and ur friend are talking... I actually believe you did catch something here

Well like i said i could be wrong, to be honest i hope i am, i will ask some of my friends to check it out tomorrow and get their opinion, one of whom is a expert in such fields and will ask him to have a look and will let you know what he says, if he comes back with, its not either of those two women, then i will be happy to say its paranormal, but right now im on the fence about it, no offense to anyone, i just like to be sure

well I'm not saying I'm right eather... It's also just my opinion
