Under?

After hearing what some believed mention of a portal in the home during the ghost box session in the green room, Max asks the entities if the portal is under the house. In this clip, he is trying to verify that it's under the house. The response to his questioning is stunning to me.

I have enhanced this audio clip by running it through noise reduction and then slowing it down. I was absolutely blown away when I heard what was being said! At first I thought the voice was saying, "Rest, baby." But, then I left for a minute and came back. As soon as I put the headphones back on, I heard it very clearly, "Yes! Leave it be."

I am uploading both the original and the enhanced version of this clip. I am interested to read what others might have to say about this particular clip.
