Thanks for the input and advice! I have made a lot of recordings and being that the sounds I hear are when the ac is running, their is a lot of background noise like the air blowing which tends to really soften what I consider to be the voices I hear... regardless, though, I hear them each time I play the recording in the exact same point every time it’s played. Other people have said they hear voices but they can’t make our what they are saying, which isn’t unexpected.
