I Found One..

So I was messing around with a recording app on my phone and left it on all night, out of curiosity. Upon examing the footage that litterally took all day lol, I came across an evp. Not only was I creeped out, because it was right above my head where I was sleeping, I was interested to research on the history of this home.
What I was wondering is where would I begin my research to start learning about this homes past?

I have included a link to where you can listen to the EVP if you would like
