all the talk of 3D sound made me remember something I read about a long
time ago - holophonic sound.  has anyone else heard of this?  apparently
an Argentinian physiologist named Hugo Zuccarelli came up with a way to
record holograms of sound.  he achieved a three dimensional sound that
maintained its spaciousness regardless of positions of speakers, number
of speakers, or position of listener relative to the speaker(s).  when I
first read about it seven or eight years ago he was refusing to release
his secrets.  i guess peter gabriel and paul mccartney tried
unsuccessfully to buy the technology from him.  has anyone heard
anything since then?  it would seem to be the holy grail of 3D sound.

i have a hard time believign that there exists a system where position of
listener("sweet-spot") and # of speakers are not determinite upon
eachother. -- but if you do have access to a number of speakers i would
think ambisonics(or wave-field synthesis) gets pretty "holographic"..
