SettingtheAfter-SilenceStartLevel
If the above algorithm is tending to under-correct when the vocalist starts singing
after a pause, you can, if you wish, set the ‘After-Silence Start Level’ by moving
the threshold fader while the plug-in is receiving silence or is non-active.
If you move the threshold level while there is silence or no signal, this will tell the
plug-in what level to assume when the signal comes back after going away for a
while. This level will remain indicated on the graph as a ghost line.
3.3.3 BandpassFilterModes
BandpassMode
By default, the Oxford SuprEsser uses a bandpass filter (along with its inverse
filter, the band-reject filter) to isolate the audio in the frequency range selected.
The FREQUENCY and WIDTH controls defines the low and high edges of the
filters used, and the SLOPE/Q control defines how quickly a signal blends from
gain-ducked to non-gain-ducked in the frequency spectrum. The effect of less
steep slopes is to give a smoother blend between gain- reduced and
non-gain-reduced regions of the frequency spectrum, at the cost of a less specific
trigger.
In this mode, the bandpass filter is created by using pairs of Oxford R3 Filters,
giving a total of up to 72 dB per octave of separation.
There are three other modes possible, which automatically switch into operation in
certain situations:
High-Q NotchMode
When you reduce the WIDTH control all the way down to 0.2 octaves, you activate
High-Q Notch mode. In this mode, instead of using R3 Filters, the plug-in uses
four Oxford EQ Type-2 Filters, giving a total of 80dB of gain reduction at the centre
point of the notch. This mode is useful when the band of energy you are interested
in reducing is extremely narrow, or virtually a single frequency, like a whistle.
In this mode, if desired, you can reduce the Q of the filters by reducing the SLOPE
control. The effect of this is to give a smoother blend between gain-reduced and
non-gain-reduced regions of the frequency spectrum, at the cost of a less specific
trigger.
