3D Audio in film?

Hey guys/girls

I am currently doing my dissertation for my audio engineering degree. I'm exploring how 3D audio could be used in the creative media industry.

I'd quite like to start a discussion and gather some opinions.

For those that don't know. 3D audio enables sound, using only a stereo setup, to be placed in a 3 dimensional space around a listener. It is deemed more realistic than 5.1 and other formats. As it can be achieved using only a stereo setup it is also a cheaper option/more accessible than 5.1 etc.

http://www.youtube.com/watch?v=IUDTlvagjJA - This is a classic example of the 3d effect i'm talking about. You will need to use headphones for this example.

Current advancements mean that in the near future, films could feature this type of surround sound.

Is this an idea that appeals to people?

It would be good to hear people's opinions.

Also I'm conducting a small survey (7 questions) for this project. If you have the time it would be great if you could fill it out.

If you've not got time, no worries :)
 
Sorry about that guys. Thanks for letting me know and for giving feedback. Any opinions on 3D audio being used in film?
 
I usually watch movies/play games with 5.1 surround sound but must admit that, that video did sound really realistic. I`ll watch out for more films with sound like that.

3D Audio is generally experienced wearing headphones; I almost never wear headphones while watching movies. I do often wear headphones while playing video games, though. I'm generally a big fan of spatial audio in games.

Some additional thoughts. At 3:30 as he talks about walking around you, you can change whether he's walking around the front or the rear just by thinking about it. You can't differentiate between front and rear as you could with a traditional surround setup or in real life. I theorize this is because in real life your head isn't completely stationary. Even slight movements will change your ears positioning, so that allows you to triangulate the sound. While this is really cool technology, and awesome for First Person games, I don't see it catching on in traditional film. It'll be exciting once we get more realistic virtual reality, though.
 
I dunno, the reason your ears curve round at the back is to alter sounds coming from the rear to make it possible to differentiate from front/rear. Squirt white noise through some cans and use a notch filter round about 3k, you should hear the noise moving back and forth.
