A Q and A plus a link from recent emails: Name of sender: Evil Joe
I was wondering if the binaural effect would be the same if I had a surround sound speaker system. Like two front speakers, two rear speakers, and a subwoofer/center speaker. Thanks.
Hi EJ:
Most modern binaural recordings sound excellent in plain stereo, and will probably sound very good on a surround system, just as good stereo does.
But it will not be surround sound, neither will it sound the same as Binaural played back with headphones, or with just two "crosstalk-cancelled" stereo loudspeakers.
Binaural recordings played back through good headphones can also reproduce the up and down dimension: above and below as well as around you in a horizontal circle, and reproduce the effects of closeness or distance much better than a 5.1 surround speaker setup can.

There are stories within stories, even in this Radio Lab program on "Emergence" which made my head turn more than once to see the source of the sounds. Of course, then the illusion evaporated and I refocus on the message. Download the MP3 of the Radio Lab program "Emergence" by clicking on this line
So what do we make of recorded sound in our lives? Does the affect alter our paths or is the act of listening everything? ...and what does that say about background use in movies and the rare television use? Can you see the story?

This snippet is from the binaural discussion on Sursound but not in that item and/or item comments. "Both Head Acoustics and Bruel and Kjaer have made products for doing binaural recording or measurements using a human head. They are like the Sennheiser MKE2002 in that they place microphones close to the ear canal entrance of a human subject. I have used the B&K 4101 and it works much better than the MKE2002. It is also much more expensive than the Sennheiser device. It is important to note that you need to know what the diffuse-field response of the system (microphone plus head) is, so that it can be equalized out in order that the recording can be played back on diffuse-field equalized headphones, or on loudspeakers."

This snippet is from a Sursound thread that is not a comment in the entry from last Thursday. Ambisonic => Binaural: It is possible to produce material ambisonically, either using studio techniques or by recording with a soundfield microphone, and then to convert it to binaural. It should also be fairly trivial to apply head tracking in order to fix the sound images to the surroundings, and not with the listeners head. The basic technique is to use a virtual reproduction system, and associate an HRTF with the location of each of the virtual loudspeakers. In this way, by summing up the ear signals from the HRTF filters from each of the loudspeaker location, one can calculate the ear signals that would have been heard if the listener had actually been listening to the loudspeaker reproduction. This virtual reproduction idea works in principle with ANY loudspeaker system.
Motion Tracked Binaural at CIPIC: The folks at CIPIC, notably Ralph Algazi and Richard Duda, have published a number of papers on a binaural-like system that they call Motion Tracked Binaural, or MTB.

Binaural v Holophonic is the subject of this page of discussion forum
You'll find links, including one to the famous holophonic Zuccarelli matchbox, discussion of binaural related to the Tuesday, September 26th item, and an audio related website with an interesting operational model. The first link in the page is dead.

Ah, researching binaural HRTFs in Paris in the Spring...http://www.limsi.fr/Formation/prop_these/theseKatz.pdf The subject of this thesis relates to the study and the development of several models for HRTF adaptation used in 3D audio rendering for a given individual, without using of individual HRTF acoustic measurements.
