• The light green line.
This is simply a graphic representation of the Offset parameter.
The light green Offset line should be adjusted so that it appears as close
above the yellow noise floor graph as possible. The dark green spectrum
plot is there to help you fine-tune the Offset setting, so that only the noise
is removed, not parts of the signal (ideally, the light green line should be
between the yellow line and the spectrum plot).
Parameters
Parameter Description
Freeze If you activate this button, you “freeze” the noise floor detection pro-
cess. The yellow noise floor graph in the display will hold its current
value (as will the numeric noise floor value display below) until you de-
activate Freeze. This allows you to take a closer look at the readings.
Reduction Governs the amount of noise reduction. The display below this fader
shows the amount of dB by which the noise level is being reduced. The
final result also depends on the Ambience parameter, and on the auto-
matic Ambience and Transient analysis of the original material, as de-
scribed above.
Ambience This parameter is used to specify a balance between the noise suppres-
sion and the amount of natural ambience, which is essential for a natural
result. With a low Ambience setting, the sound can become somewhat
lifeless and sterile. A high setting, on the other hand, preserves more of
the ambient character of the sound, but the noise suppression is less
effective.
Offset This parameter serves as a threshold, governing the overall level at
which the noise reduction is performed. For optimal noise reduction
with a minimum of sound coloration, this parameter should be set to a
value slightly above the noise floor level. To help you do this, the offset
value is shown as a light green line in the noisefloor display, while the
noise floor is shown as a yellow line.
A/B/Store These are described below this table.
Classic When this is activated, a less CPU-intensive version of the DeNoiser al-
gorithm is used. Use Classic mode if you are short on processing
power. However, for optimum noise suppression, we recommend that
you deactivate Classic mode.
Bypass When this is activated, the signal passes through the plug-in but you
don’t hear the results of the processing. Use this to compare the sound
with and without processing. Note: the analysis is always performed, re-
gardless of the Bypass switch. This allows you to monitor the noise
floor, spectrum and level in the spectrum display.
