SvfInputMixing is a State Variable Filter
that provides a configurable mix of lowpass, bandpass and highpass filtering. It
can also be used as a peaking filter or notch filter.
SvfInputMixing is a C++ port of the algorithm described in the paper
"Input mixing linear trapezoidal State Variable Filter (SVF) in state increment
form", by Andy Simper of Cytomic.
FastMath contains some fast approximations for trigonometric functions.
