The C* Audio Plugin Suite reincarnates as version 0.4.0.
CAPS is a collection of LADSPA plugins enjoying worldwide favour for
its instrument amplifier emulation. In addition, it provides a
sizeable assortment of acclaimed audio DSP units, sound generators and
effects. CAPS is distributed as open source under the terms of the

This release sees the addition of the fine work of David Yeh at CCRMA

David for his brilliant contribution, and I'm quite positive that

The last new plugin is Eq2x2, a two-channel 10-band graphic equalizer
modeled after an analogue design.

Parameter smoothing (which is performed in order to prevent zipper
noise) has been refined never to occur at the start of processing.

and SSE3 extensions on the i686 platform, providing slight performance
gains and automatic denormal protection. The HTML documentation has
been thoroughly updated to reflect all changes. Finally, thanks to
Paul Winkler CAPS now comes with an improved RDF file containing
