Figure 21.1: Signal Flow
The block diagram above illustrates the overall structure of the processing system provided by the Precision
DeEsser. The diagram does not indicate the metering blocks.
Now lets examine the various processing blocks indicated in the diagram.
Ess Band Filter
When the signal is routed to the Precision DeEsser it runs through a filter block that allows you to define the
frequency area to be processed.
Figure 21.2: Ess Band Filter Controls
The filter controls are:
• Center: Sets the center frequency of the ess band filter.
• BW (Oct): Sets the bandwidth of the ess band filter. Higher values widen the filter.
• Sharpness: Sets the slope of the filter
To use the filter, set the Center parameter as close as possible to the undesired frequency. Use the BandWidth
control to set the overall width of the filter; a narrow bandwidth will let less audio through to the compressor,
while large bandwidths will process more overall. By using the Sharpness control you may shape the slope of
the filter, to adjust the transition between the processed and non-processed audio.
Compressor
The next processing block is the compressor. The compressor is used to reduce the level of the audio within
the filter boundary once it exceeds the threshold.
