1028      "This package provides a LADSPA plugin for a four-band parametric
1029 equalizer.  Each section has an active/bypass switch, frequency, bandwidth and
1030 gain controls.  There is also a global bypass switch and gain control.
1031
1032 The 2nd order resonant filters are implemented using a Mitra-Regalia style
1033 lattice filter, which is stable even while parameters are being changed.
1034
1035 All switches and controls are internally smoothed, so they can be used @code{live}
1036 without any clicks or zipper noises.  This makes this plugin suitable for use
1037 in systems that allow automation of plugin control ports, such as Ardour, or
1038 for stage use.")
