EasyQ is a
maintenance update with a little bug fix related to
color scheme handling.
EasyQ is an
easy-to-use equalizer with an arbitrary number of
filter stages in series connection. Each of the
filter stages can operate in one of the following
modes: peak/cut (aka bell or parametric EQ), high-
or low-shelving, notch and low- or high-pass (both
with either 6 or 12 dB/oct slope).
EngineersFilter is a filter plug-in that
allows for extremely steep filtering. It achieves
this by implementing high order IIR filter design
methods that are commonly used in science and
engineering, namely Butterworth, Chebychev, inverse
Chebychev and elliptic (aka Cauer) filters. Each of
these filter design methods can be applied to create
low-pass, high-pass, band-pass, band-reject,
high-/low-shelving and peak/dip filters of orders up
to 20.
EngineersFilter now
includes two new approximation methods: Bessel and
Papoulis. The Bessel design approximates a linear
phase response in its pass-band and the Papoulis
design achieves the maximum negative slope at the
cutoff frequency when a monotonically decreasing
magnitude response is assumed.
