caps, the C* Audio Plugin Suite, is a collection of refined LADSPA
units including instrument amplifier emulation, stomp-box classics,
versatile 'virtual analog' oscillators, fractal oscillation, reverb,
equalization and others.
some of caps is an improvement over previous efforts (the rewritten
amplifier emulation plugins for example do 8x oversampling using
polyphase filters, for much cleaner sound) but most of the plugins are
ex nihilo creations.
for those with an interest in DSP effects but no time or opportunity
to run the plugins, the data sheets provided through the above
document may be interesting.
