Audio effects
• A line that passes through the effect (with no square input/
output indicators) represent a bypass connection – the audio
on that speaker channel passes the effect without being pro-
cessed.
• A “broken” line indicates a broken connection – the audio on
that speaker channel will not pass on to the output at all.
Here, the effect will process the L and R channels. The Ls, Rs and C
channels are not processed, while the Lfe connection is broken.
Operations
You can move connections to the effect inputs and out-
puts sideways to route the audio to/from inputs/outputs
other than the standard configuration. To do this, click the
arrow buttons to the right.
• The upper two arrows move the input connections, and
the lower two arrows move the output connections.
If the “Link” checkbox is activated, the input and output connections will be
moved at the same time. This is the mode to use when you simply want to
process other channels than the default, without any cross-connections.
• If you move inputs or outputs independently of each
other, this means you create a “cross-connection”.
The audio on the Ls-Rs channels is processed in the plug-in and output
on the L-R channels. Since the L-R channels are bypassed, this means
the final L-R output will contain both the original L-R signals and the
processed Ls-Rs signals.
• If a channel is bypassed (a straight line is shown
through the plug-in) you can click the line to break the
connection.
Click again to replace the broken connection with a bypass.
• Clicking Reset takes you back to the original standard
connection.
Ö Changes you make in this window are audible immedi-
ately.
Adding insert effects to busses
All input and output busses have eight insert slots, just like
regular audio channels. The procedures for adding insert
effects are the same.
• Adding insert effects to an input bus (Cubase only) al-
lows you to record with effects.
The effects will become a permanent part of the recorded audio file (see
the chapter “Recording” on page 65).
• Insert effects added to an output bus will affect all audio
routed to that bus, like a “master insert effect”.
Typically you would add compressors, limiters, EQ or other plug-ins to
tailor the dynamics and sound of the final mix. Dithering is a special case,
as described below.
Ö Please note that the input/output busses only appear
as tracks in the Track list, when their automation W(rite)
buttons have been activated once. I.e. you can only use
the Inspector section to make Inserts settings for the bus-
ses if you have activated Write automation for the respec-
tive bus beforehand.
However, you can always make Inserts settings in the Channel Settings
window and the extended mixer.
Dithering
Dithering is a method for controlling the noise produced
by quantization errors in digital recordings. The theory be-
hind this is that during low level passages, only a few bits
are used to represent the signal, which leads to quantiza-
tion errors and hence distortion.
For example, when “truncating bits”, as a result of moving
from 24 to 16 bit resolution, quantization errors are added
to an otherwise immaculate recording. By adding a spe-
cial kind of noise at an extremely low level, the effect of
these errors is minimized. The added noise could be per-
ceived as a very low-level hiss under exacting listening
conditions. However, this is hardly noticeable and much
preferred to the distortion that otherwise occurs.
