The band toolchest that appears on your initial launch of a DynPEQ plugin has several drag-and-drop items for quickly configuring the plugin.
The top four entries are single band starting points with neutral settings. The generic peak and shelves place the respective band type with zero boost/cut and dynamics turned off. The generic dynamics setting turns the band type off (which makes it broadband) and activates both the compression and expansion points.
The drawer at the bottom of the toolchest contains several single bands for particular applications. The top part of the drawer contains several EQ band settings. The dynamics portion of these bands enables rotation point compression with a small ratio and a high threshold–with little effective compression but ready to configure.
The bottom part of the drawer contains bands for applications to specific problems, such as de-ess and de-hum, along with a few single bands created by users.
The drawer second from the bottom contains several multiband settings. The top four items are general initial setups for the Quartet bands. The bottom items are more specific setups along with user submissions.
There are two drawers within the multiband drawer. The first one contains several bandsets to approximate the demodulation of several popular Analog Noise Reduction (ANR) systems. The bandsets with “Ideal” in the label are based on published specifications, and the bandsets with “Practical” in the label have been hand-tuned.
The second subdrawer contains bandsets to approximate the RIAA curve at several sample rates. The bandsets have been optimized to model the RIAA curve to within 0.2 dB from 20 Hz to 20 Khz.
Of course, you are welcome to add your own go-to bands and bandsets to the toolchest, and those entries will persist on that computer.
The default band toolchest that ships with Trio is the same as Quartet’s save the bandsets containing 4 bands.
IMPORTANT NOTE: DynPEQ is a general purpose dynamic equalizer and is not designed after any specific architecture of commercial Analog Noise Reduction (ANR) systems. There will, at minimum, be phase differences between DynPEQ decoding and that of the original ANR systems.
