This excerpt of the show represents all that circulates 
from Bear's master cassette.   The rest of the setlist 
that is missing is unknown. It is likely that several 
generations occurred before the digital transfer.

Tech Notes

FLAC/SHNs were decoded to wave.  Wavmerge used to reassemble 
the tracks back to 1 long wave.  CEP2.0 was used to align & 
synch both of the sources.  SF8.0 used to adjust the volume 
for the center and LFE channels.  Surcode CD Pro DTS was used 
to encode to DTS.

Notes

The SBD source is clearly several analog generations old.
If I had to guess I would say easily 4 or 5, possibly more.
Call me crazy but there was also some LP sounding pops and
crackles on this.  I was able to remove all but the most
severe.  The analog hiss was as loud as the music in the
quiet parts.  Most notable on Morning Dew.  Trying to
remove this hiss without an adverse reaction to the music
was pretty much impossible.  However, leaving the hiss 
alone was leaving this recording practically un-listenable 
IMO.  So I went ahead and performed some noise reduction
with a very gentle hand.  Also a high frequency EQ to
further reduce the ravages of multiple analog generations.

Besides the hiss there is some pretty bad distortion and 
over saturation on the loud portions of the SBD recording.
These defects were unfixable but quickly pass.  We will 
hope that Bear's master is free of those. 

The AUD was a darn good capture for 1969 using very modest 
taping equipment.  A lady close to the mics can be heard.
Astute enough to make the call on Morning Dew just prior
to the beginning of the song.  Perhaps she had a view of
the setlist.

The condition of the SBD is so poor I actually prefer the 
stereo matrix mix in this situation over the multi channel
version.  The blending of the 2 sources help spruced up
what is a very tired board tape.  I do feel like this
project was worth the effort even though the relative low
sound quality on this project.  We can always hope a
better SBD copy, hopefully off the master, will somehow
materialize.  It would be very nice to upgrade that portion
as the AUD actually does work well in the surround sound 
setting. Giving the listen an historic perspective of a
1969 Dead show.  Talkative chick and all.

Jim Wise's masterful job done on the 11/8 show was added
for good measure.  Besides filling up the CD a bit more
it will also bring your ears back to life with a 1969
Dead recording we all know and love.  The complimenting
AUD helps open things up a bit and also gives you a
much better idea of what Phil really sounded like that
night.  It isn't an overly bright or punchy AUD however.

More On DTS

Today's audio standards are moving towards multi-channel 
sound, like DTS and Dolby Digital.  While the Audio-CD 
standard (Red Book) hasn't changed to accommodate these 
new sound formats, it is still possible to go around the 
specification and to put a 5.1 surround recording on a 
regular Audio-CD.  To play a DTS-Audio-CD you must connect 
your DVD/CD player via a digital cable (optical or coaxial) 
to your DTS Dolby-Digital receiver. It is not 100% sure that 
your receiver will recognize a DTS-Audio-CD, so the first 
time you're trying to playback a DTS-Audio-CD you must do 
a test to determine if it can. Begin with the volume very 
low, start the disc and rise
