Ess Band Transfer Function
Figure 20.7: Ess Band Transfer Function
The ess band transfer function is a combination of a visual representation of how the de-esser is processing
the signal and an intuitive controller for the associated filter. This display is sometimes called a “Cartesian
Graph” by other manufacturers.
The horizontal axis provides frequency calibration in Hertz (Hz). The vertical axis provides level calibration
in decibels (dBr). The heavy green line indicates the shape of the filter. The center frequency is represented by
a large dot in the transfer function with two smaller dots flanking it.
Clicking on the large dot and dragging will allow you to adjust the center frequency. Mac ⌥ (Option)–click
or Windows Alt the dot to adjust the bandwidth (dragging right increases the bandwidth, left decreases the
bandwidth). Click and drag the smaller dots associated with a larger dot to adjust the filter bandwidth.
To dismiss the filter curve, click anywhere in the black area of the transfer function. This will deselect the filter
point, and the only trace displayed will be the green master curve.
Spectragraph Analyzer
Clicking the SpectraFoo™ logo in the upper right hand corner of the transfer function will activate the spec-
tragraph, showing the realtime frequency analysis of your signal:
