3d sound? wait what?

so early this year to coincide inside with their tour AmazingPhil and DanIsNotOnFire made a book. Then today they announced that they have made an audio book version. I was really excited by this and couldn't wait to watch the trailer they had made for this. Thought I wasnt really sure what to expect and when It started off as a video I was like okay maybe it will just be a video where they say that its available to get as an audio book.  Though it was better than that but also messed me up a bit as about 40 seconds in they put a blind fold on the camera as if you where there. They said that we had to close our eyes until they said so. I didn't think much of it thinking it would just be a sound bite but it wasnt. As they had used 3D Binaural’ technology to make it sound they where talking with you in the room. It was amazing but it messed me up a bit as it was like they where standing right next to you. Everything they did felt like it was happening next to you. There was a part where they apologised for getting wet after phil set the curtains on fire to which they used a towel to dry you off. However Dan ends up getting a hair drier and it felt really weird as it really felt like they blow drying you. I remember putting my hands on my head to double check that there wasn't anything there. 

Over all I thought that this was a really cool audio book trailer and so much more than i expected it too be. It did mess me up in a few places. Though having watching this I have decided it would be a cool thing to try out myself as something like this could really be the way forward for things like 4d cinema.
