Parametric Equalization (PEQ)
Three bands of parametric equalization are provided for fine
tuning if necessary. None of the factory-supplied presets use
the parametric equalizers, but they are provided to create
notch filters or other effects if necessary. Each filter has a
gain control with a +/-12dB range, a center frequency control
that varies from 20 Hz to 22.050 kHz, and a bandwidth or “Q”
control that varies between 0 and 10. Normal default settings
for all bands are Gain = 0dB, in other words bypassed.
Multiband AGC
This section is the heart of the dynamics processing engine.
A multiband AGC (i.e. compressor) that allows for medium
ratio (3:1 is default) adjustment of audio band. Adjustable
parameters are divided amongst three tabs:
Main
•
Compression Ratio: 1.0:1 - Inf:1 (default: 3.0:1)
•
Range: 0dB - 36dB (default: 24dB). Range sets how
much gain expansion above unity is able to be
performed. This adjustment is reflected in real time by
changing the AGC meter scale.
•
Progressive Release: 0 - 100, slowest - fastest
(default: 50). Sets the speed at which the release time
is increased faster at very low gain values. This
feature approximates a logarithmic release to help
recovery from dramatic gain reduction more quickly.
