In practice it has limited utility.

  If you want to experiment with binaural recording and don't want to spend lots of money on the Neumann, there are microphones that will fit in-ear like earbuds. One of the less expensive examples: http://www.soundprofessionals.com/cgi-bin/gold/item/SP-TFB-2 http://www.soundprofessionals.com/cgi-bin/gold/item/SP-TFB-2 Of course, the sky's the limit when it comes to microphone pricing, and as with anything in audio, it's that last 10% that costs a fortune. Edit: Neumann also has an Android app that will allow you to quickly calculate stereo recording angles when using conventional mics. Unfortunately, it requires Adobe AIR to be installed as well. https://play.google.com/store/apps/details?id=air.com.neumann.recordingtools https://play.google.com/store/apps/details?id=air.com.neuman...

Very interesting. I knew that time differences were more important than intensity for localisation, but I did not know that the most important part for localisation is actually the reflection of sounds by the pinnae. Quite surprising to find out the reason why our ears are shaped the way they are.

Suggests an interesting optimization for immersive head-tracking VR systems might be to dynamically model pinna-reflection to correctly relocalize sounds vertically, as well as in the horizontal plane. How good is 3D sound modeling in game engines today?

  I know this is something Oculus have been putting some effort into, but I'm not up on the technical details. edit: yep, they're using simulated binaural sound http://www.polygon.com/2015/2/12/8028379/binaural-3d-audio-virtual-reality-oculus-rift-project-morpheus http://www.polygon.com/2015/2/12/8028379/binaural-3d-audio-v...
