4.1.3 InputMonitorSection
InputLevelMeter
This meter is designed to give exactly 1dB per LED for the top 18dB of dynamic
range, and 2dB per LED thereafter. This gives a clear and intuitive impression of the
working headroom.
LevelTrimdB TouchPad
This allows you to adjust the input signal level by up to +/- 12dB.
Although it is true that, in default operation, the threshold of the compressor is more or
less level independent, you may wish to adjust the input level to bring peaks down below
0dB, because the threshold cannot go above 0dB.
4.1.4 ListenSection
This section of the plug-in allows you to control what you are listening to in terms of the
crossover that mixes the outputs of the two signal streams.
Some users prefer to isolate the troublesome sound, and keep narrowing the bandpass
filter to just contain it — this way the compressor affects only the absolute minimum of
the frequency spectrum. You can do this by clicking on the INSIDE button, labelled with a
bandpass symbol.
Others prefer to work in band-reject mode, where you listen to the narrow
band-reject-filtered signal and narrow the band until you just begin to hear the
troublesome sound. You can do this by clicking on the OUTSIDE button, labelled with the
band-reject symbol.
MIX Button
This sets the cross fade exactly to 50%, providing an equal mix of band-reject signal
and (compressed) bandpass signal, which will be sent to the output.
INSIDE Button
This sets the crossfade so that you are listening to output of the bandpass filter, as
processed by the compressor. You can then use the EFFECT: IN button to listen with
or without compression, or use the WET/DRY control to adjust the blend between
compressed and non-compressed signal.
In this mode, if you sweep the centre frequency of the band up and down the
frequency spectrum, you hear only a narrow part of the spectrum, and so it is easy
to home in quickly to locate exactly where in the spectrum a troublesome noise is.
