(When listening to these do so with headphones, without is like trying to view a 3d image without the glasses)

If you click on the above link it will take you to a page on the radio drama revival site.  Scroll down the page to the end of the article (not far) you can play a good example of the binaural technique.

Obviously just as with the 3D picture, binaural is all about creating a greater depth of space and therefore creating a greater immersion for the audience.   It can be done in several ways you can take normal recordings and mix them in the edit, by panning them left or right (by however much the material requires), when doing this it is best recorded in mono (so to one track) that you can then mix your recording left and right without the movement having been pre-determind.  For a binaural recording which will result in 3D sound you need too mic recording to separate channels but recording as one file.  This can be done on the most basic of field recorders.  To best create a true 3d sound we can place the microphones into the same positions as our ears with something of similar shape and density to our head in between the two microphones, this then emulates the way in which we hear.

The above link is another example of binaural sound.  The story telling is pretty abysmal, yet when you get to 0.53 in the clip the composition and it’s place in the audio field is very cool.
