is done by adding a second delay.
The second delay time does not have to be within 40 msec of the source
as long as
it is within 40 msec of the first delay. So by making the second
delay longer than the
first, the sound is
11
thickened
11
even more. Doubling
and Tripling are different from simulated reflections because levels of
the delayed signals are not reduced.
LOCALIZATION
Using delay to perceive the direction of a sound can be accomplished with
a modified
set-up. Connect the input via the INPUT MIXER OUT to the left
channel of the monitor amplifier and connect the MASTER OUTPUT to the right
channel. Now by using only one delay of short duration, the sound will ap-
pear
to be coming from the left (the input). The longer the delay, (but less
than about 30 msec) the more the effect is enhanced. One can also achieve
the
effect by monitoring the two delays, A and B, one in each channel from
their rear panel outputs (instead of INPUT MIXER OUT and MASTER OUTPUT}.
The location of the sound can then be moved from left through center to right
by changing the relative delays. In this way single instruments or voices
can
be positioned in the mix-down of complex multi-track recordings. It is
the left and right discrimination which can be accomplished with time delay
that enables the synthesis of stereo from a mono source.
AUX INPUT
M.93 accomodates two independent inputs, IN and AUX, which can be used
interchangeably or in combination in the
INPUT MIX. Thus all functions de-
scribed using the
IN source can be performed with the AUX source or with a
combination
of IN and AUX sources equally well. IN and AUX can also be com-
bined in the OUTPUT MIX to provide direct signal output from either one or
both sources.
To connect a second source use the AUX INPUT on the rear panel.
The effects in this section, including echo, reverb, stereo simulation, and
vocal doubling will all be discussed again using more sophisticated tech-
niques
available with M.93. But the basic principles are here in the straight
delay.
