I met Juan Pablo before the beginning of this quarter as I had a
clear idea of what I wanted to do with the project but wanted a good starting point.He referred a good
paper on spatial orchestration.I had a
meeting with Sreedhar Devarajan a Neuroscientist for studying more
about auditory localization.
He instructed learning in the auditory localization pathway of the barn
owl. Eric I Knudsen. Nature. 2002 May 16; 417(6886): 322�328. doi:

I searched Pubmed with the following search terms, and came up with many more hits. "Auditory
localization Eric Knudsen". Also searching with the following search
terms ""spatial audio" (including the quotes) gives many interesting
articles.
I decided to use Ambisonics for the first piece
* It provides full surround -- with height ("periphony") -- while requiring only four channels total (B-Format or UHJ)
* The surround-sound image remains largely unaffected by listener position -- no "sweet spot"
* Images can appear anywhere, not solely in the speaker positions
* You can place the loudspeakers in convenient positions -- not necessarily a square (B-Format or UHJ)
* The mono/stereo-compatible hierarchical encoding scheme, UHJ, allows the transmission of Ambisonic material via two or more channels.
* Undecoded 2-channel UHJ provides significant "super stereo" effects, comparable to those of other systems.
* No decoder is required for G-Format, although a decoder may be needed for other formats
