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.
