3D SOUND at NSA Convention'98
	    _____________________________


In 1998 the NSA Stereo Theatre will not only provide 3D vision but  also
3D  sound  for  those  who  wish  to take advantage of this for their 3D
presentations.

If you provide a 2 channel stereo sound track with your pictures we can
turn it into multi-channel sound as heard in most modern movie theatres.

How  it  works  -  from 2 channel stereo (basic 3D sound) we can  derive
(not synthesize) 6 channels.  There will be 5 front channels (far  left,
left,  center,  right, far right) and a surround channel through out the
room.  There are an additional 2 sub-woofer channels.   (left  &  right)
These  channels  supply  the  deep  powerful bass heard in many theatres
today.  We can optionally synthesize a  sub-harmonic  bass  octive  that
adds  realism  to  most  music  and effects.  (This is also used in many
movie sound tracks.)

Source: To take advantage of this you will need to  supply  either  a  2
track  stereo recording (tape or CD), a 3-4 track reel-to-reel, or a 3-4
track casette.  If you supply a 2 track stereo music recording, you  may
give  us control signals on another tape with or without narration.  For
the 4 track tapes track #1 is the left channel, track #2  is  the  right
channel, track #3 is narration, and track #4 is for control signals. (If
you have 2 separate tapes we will probably record them onto one 4  track
tape.)  A  control  tape will use the left channel for narration (and/or
monaural music if not provided in stereo) and the right for the  control
signals.   We  can  handle Dolby or DBX noise reduction if used.  If you
need additional information you may e-mail me at: cowardin@juno.com
