for sursound this will be one more necessary go at the eternal sweet spot
topic -this time for 3d audio.

mixing for live theater offers additional obstacles for 3d that appear to,
at least currently, suggest irreconcilable solutions.

as 3d mixing in the theater itself may be limited to just a couple of days,
imaging must be dealt with beforehand. this makes some sort of B format a
natural to preserve the intent of the artist: once things are imaged in 3d,
the material can be output to any number of speakers (preferably at least 8
to form a cube) in any theater. this could, for some including myself, be
quite satisfactory for even audience members seated at left, right, front
or back extremes in the hall -providing movement of sounds is limited to
the periphery of the hall.

but what of sounds moving diagonally across the space? the localization of
sound movement may tend to become unacceptably blurred for audience members
seated further and further away from the sweet spot. and so...

as an alternative, a 3d mix image may instead be hard wired into a discrete
number of tracks, and for extreme movement effects perceivable to all such
as, diagonal movement from left front to right back, a sound dedicated to
one channel and one speaker may be panned diagonally across the room
through another single channel and another single speaker. but this
requires that the artist know in advance how many speakers there will be,
how they will be placed, and how the sounds will behave in a space that may
never have even been visited by the artist (depending on the space, perhaps
mix would not be desirably so extreme).

or has this already been solved by the B formatters? perhaps by an
extremity adjustment that reduces, or completely diminishes the volume of a
particular sound (control of a particular soundfile in a computer) in
surrounding speakers to allow for adjustment to the hall/speaker
arrangement. -again, i'm not just speaking about changing number of
speakers and placement, but about achieving an extreme panning effect
dramatically perceivable by audience members seated at the extremities of
the theater.

apology for omission in my previous reports on surround interfaces: of
course csound does surround. and thanks again to all who provided
information.
