Binary package “fil-plugins” in ubuntu oracular
parametric equalizer LADSPA plugin
Four-band parametric equaliser. Each section has an active/bypass switch,
frequency, bandwidth and gain controls. There is also a global bypass
switch and gain control.
.
The 2nd order resonant filters are implemented using a Mitra-Regalia
style lattice filter, which has the nice property of being stable
even while parameters are being changed.
.
All switches and controls are internally smoothed, so they can
be used 'live' without any clicks or zipper noises. This should
make this plugin a good candidate for use in systems that allow
automation of plugin control ports, such as Ardour, or for
stage use.
