Shuffler
Shuffler is designed to be used with Binaural record-
ings, or with any recording technique involving only
omnidirectional microphones placed at close dis-
tances (such as true Binaural or directional micro-
phones spaced to equal ear-to-ear distance and aimed
forward). It adds a significant amount of L-R low fre-
quency information. If widely spaced omnidirectional
microphones, or accent microphones, are mixed with
the Binaural pair, Shuffler should be used before the
microphone signals are mixed to avoid a severe boost
in L-R information.
Shelf
Adjusts the +3dB frequency of the Shuffler shelf.
Flip & Swap (Right Channel Phase Invert)
Enables either a change of audio channels, or a polar-
ity inversion in one or both channels. This change is
made in the digital domain. The available settings are:
Channel Position
+L +R NORM
+L-R NORM
+R +L INV
+R -L INV
8-4
AUTO (Automatic DC Cut)
Enables routines for correcting DC offset from material
recorded through analog-to-digital converters that are
not properly trimmed for DC.
RESET
RESET disables all DC adjustment.
HOLD
HOLD freezes automatic nulling and enables DCL
and DCR for manual individual channel adjustment.
AUTO NULL
AUTO NULL automatically reduces +4 bits of DC error
to >48dB down for each channel. It maintains a slight
positive offset near zero to avoid toggling theMSB D/A
converters downstream. DC errors greater than -24dB
will not be nulled.
DCL (DC Offset Left) and DCR (DC Offset Right)
Replaces any previously obtained value with the slider
Polarity
value. The display indicates the percent of the correc-
NORM
tion relative to the -24dB maximum.
