Isn't what you did simple stereo recording and playback? Or, more general,
amplitude and time delay panning!?
The drawback here is the mismatch of spatial selective recording and
playback. What enter the mic from one direction leaves the loudspeaker in
all directions (assuming omni characteristic).

Betreff: [Sursound] Recreating a 3d soundfield with lots of mics.....

Recently I did a little experiment - i was creating the illusion of a barman
serving drinks to some people in a "snug" which is little room where ladies
off "ill repute" would have a drink in pubs in Ireland when only men
generally drank in pubs.
I did this by placing one microphone in the snug with two actors - and one
microphone on the bar and recording the scene. I then placed two speakers in
exactly the same place the microphones had been facing the inverse direction
(which happens to be towards the "audience"). An absurdly simple idea but it
worked fantastically well with the banning of the barman walking over to the
hatch and asking the people in the snug what they wanted creating very
effective spatialisation. Of course there wasnt the same height information.
I have since experimented with recreating whole soundfields like this with
many microphones placed in 3d to record a soundfield spaced apart and then
placing the speakers in exactly the same place. It works wondefully -
recently we did a church filling up and then people taking the places in
their pews and having individual conversations (here the cocktail effect
kicks in - you can listen to an individual conversation or just hear the
general hubbub of the church). Does anyone know of others who have miced up
a 3d soundfield in this way ? I have read a couple of things but none of
them are quite the same, best, Gus
