FX-FilteringObjects

These are all very small objects that were culled from Will Pirkle's book Designing Audio Effects Plugins in C++ 2nd Ed. They are taken either directly verbatim, or with slight name changes from the fxobjects.h and fxobjects.cpp files that you can download that accompany the book. More...

Classes
class	SynthLab::CircularBuffer< T >
	The CircularBuffer object implements a simple circular buffer. It uses a wrap mask to wrap the read or write index quickly. More...
struct	SynthLab::BQCoeffs
	Structure to hold the seven coeffieicents used in the AudioFilter object from Designing Audio Effects Plugins in C++ 2nd Ed. by Will Pirkle. More...
class	SynthLab::BQAudioFilter
	Simple version of the AudioFilter object from Designing Audio Effects Plugins in C++ 2nd Ed. by Will Pirkle that impelments a biquad audio filter. More...
class	SynthLab::FracDelayAPF
	Implements a first order APF that is used to generate a fractional delay for the physcial model of a string. More...
class	SynthLab::ResLoopFilter
	Implements a first order feedforward LPF with coefficients a0 = a1 = 0.5. More...
class	SynthLab::DCRemovalFilter
	Implements a first order HPF with fc = 2.0Hz. More...
class	SynthLab::TinyBPF
	Implements a simple 2nd order BPF. More...
class	SynthLab::LP2Filter
	Implements a simple 2nd order LPF. More...
class	SynthLab::HP2Filter
	Implements a simple 2nd order HPF. More...
class	SynthLab::TinyReson
	Minute implementation of a 2nd order resonator filter. More...
class	SynthLab::LowShelfFilter
	Implementation of a low shelving filter. More...
class	SynthLab::HighShelfFilter
	Implementation of a high shelving filter. More...
class	SynthLab::ParametricFilter
	Implementation of a constant-Q parametric EQ filter. More...
class	SynthLab::LP1PFilter
	Implementation of a one-pole LPF. More...
class	SynthLab::PluckPosFilter
	Comnination of three filters in one; note that the figure in the book does not show the variety of connection combinations and filter bypassing possible, nor the multiple output points. More...

Detailed Description

These are all very small objects that were culled from Will Pirkle's book Designing Audio Effects Plugins in C++ 2nd Ed. They are taken either directly verbatim, or with slight name changes from the fxobjects.h and fxobjects.cpp files that you can download that accompany the book.

• these are heavily detailed in the book above and at http://aspikplugins.com/sdkdocs/html/index.html and so there is only minimal documentation here
• please see the link above for more information on these objects
