Type III
Figure 9-15: Type III EQ filter style.
The Type III EQ filter increases Q as boost is
applied. Therefore, lower amounts of boost
provide a softer, “wider” EQ effect (since the
affected frequency range widens), while higher
boost tends to sound louder and more “up front”,
due to the increase in Q as the gain is increased.
The more gentle Q curve at lower settings is well
suited for overall EQ fills and more subtle
corrections in instrument and vocal sources.
Boosting or cutting by small amounts will seem to
produce the effect that your ear expects, without
the need to adjust Q. As a result, this filter style, and
similar EQs with this characteristic behavior, are
often referred to as being more “musical”. More
specifically, this style emulates the classic Neve
EQs, their modern derivatives and later SSL G
series EQs. Many current popular outboard
“boutique” EQs exhibit this same gain/Q
relationship.
Type IV
Figure 9-16: Type IV EQ filter style.
The Type IV EQ filter is a more extreme form of the
Type III filter. It exhibits a high degree of
interaction between Q and gain in order to
maintain as closely as possible an equal amount of
area under the response curve as gain is adjusted.
Type IV is the most gentle of the four EQ styles and
is ideal for large scale EQ adjustments, especially
on sub-mixes and complete mixes. This EQ style is
also ideal for any applications where subtle changes
in the overall character of the sound are desired.
For example, it can be used for mastering
applications, such as the overall adjustments that
must often be applied to entire tracks to match
other tracks on the album.
