Param Eq - Arturia VOCODER V User Manual

9.5.10. Param EQ

The parametric equalizer is a versatile way to adjust frequency response, because it can
boost (make more prominent) or cut (make less prominent) specific ranges of the frequency
spectrum. This kind of EQ is suitable for broad tone-shaping, or precise, surgical fixes. The
Param EQ has five stages: Low Shelf, three fully parametric stages, and a High Shelf. Each
has the same three associated controls.
A parametric stage boosts or cuts at a specific frequency, over a specific bandwidth (range
of frequencies). A shelf response starts boosting or cutting at a selected frequency, but this
boost or cut extends outward toward the extremes of the audio spectrum. Past a certain
point, the response hits a flat "shelf" equal to the maximum amount of boost or cut. In the
image above, each EQ stage is represented by a node. Going from left to right, here's what
each node indicates:
• Low Shelf, cutting low frequencies
• Parametric stage 1, with a sharp, narrow boost
• Parametric stage 2, with a broader, gentler boost
• Parametric stage 3, with an extremely sharp and narrow cut
• High Shelf, boosting high frequencies
The controls produce somewhat different results with the shelf and parametric EQs.
Filter Selector The five blocks (LS, 1, 2, 3, and HS) choose the desired filter for
•
editing.
Frequency For the three parametric stages, this sets the frequency at which
•
boosting or cutting occurs. With the Low Shelf, this determines the cutoff
frequency below which boosting or cutting occurs. With the High Shelf, this sets
the cutoff frequency above which boosting or cutting occurs. You can use the
Freq knob to choose the frequency, or click on a node and drag left or right.
Gain This boosts or cuts the peak with the parametric stages, and boosts or cuts
•
the shelf with the Low Shelf and High Shelf stages. You can use the Gain knob to
boost or cut, or click on a node and drag up (boost) or down (cut).
Q With the parametric stage, this determines the range over which a boost or cut
•
occurs, from narrow to broad.
