Technical information

McDSP plug-ins
CB303 adds a static and dynamic EQ at the output stage. The user can select
a  xed amount of (static) gain or a dynamic gain that tracks to the attack and
release settings of the compressor. Possible e ects include signal enhancement,
noise reduction, and harmonic distortion.
The static EQ is a normal parametric EQ. The dynamic EQ adds a positive gain
or negative gain, but only when the compressor is actually compressing. When
you compress a voice, for example, you may lose a little clarity and want to
compensate for this using EQ. This feature lets you just apply this EQ when
the compressor is actually compressing the audio. This dynamic gain uses the
same attack and release times as set in the compressor already, so the dynamic
gain follows the amount of compression.
The parametric section is placed at the output of the compressor (post-
compression), and has gain, frequency, and Q controls. The Gain control adjusts
the amount of boost or cut applied to the signal. The Frequency control adjusts the
point in the frequency spectrum where the parametric band gain is applied. The
signal amplitude at the frequency set by this control is equivalent to the amplitude
set by the gain control. The width of the parametric band, the bandwidth, is
controlled by the Q control (Q = 1/bandwidth). Large values of Q correspond to
narrow bandwidth; small values of Q correspond to wide bandwidth.
FilterBank
FilterBank has three plug-ins – the E606 equalizer, the P606 parametric
equalizer, and the F202  lter set. All FilterBank’s equalizer and  ltering sections
have an analog saturation modelling circuit to prevent digital clipping from
