Thus allowing up to two poles and zeroes in the Z-plane transform of the transfer-function. Definition at line 32 of file filters.h. Member Function Documentation std::string SynthCore::BiQuad::getXML (  int    indent = 0 )  [virtual]   Return XML representation of parameters. Used for serializing modules. Reimplemented from SynthCore::Module. Definition at line 74 of file filter.cpp. References dry, freq, FreqInput, SynthCore::Input::getXML(), SynthCore::Output::getXML(), Input1, Utils::intToString(), Utils::newline(), Output1, rez, RezInput, and Utils::space(). void SynthCore::BiQuad::setDry (  float    s )    Dry/Wet percentage. Todo: consider the soundness of this. Definition at line 69 of file filter.cpp. References dry. Module * SynthCore::BiQuad::sharedClone (    )  [virtual]   Creates a copy of the Module. If any ressources can be shared across a voice the method should utilize it. Reimplemented from SynthCore::Module. Definition at line 20 of file filter.cpp. References BiQuad(), dry, filterType, SynthCore::Module::firstVoice, freq, SynthCore::Module::hostVoice, SynthCore::Module::ModID, and rez. void SynthCore::BiQuad::updateFreqAndRez (    )    The filter coefficients are not calcuted every samplestep (That would be to time consuming) Call this method to update coefficients.

Referenced by BiQuad(), and update(). Input* SynthCore::BiQuad::RezInput   Resonance (that is: Q factor) Input. This number is just a parameter used in determing the filter coefficients. For low and high pass filters it is a resonance factor. Definition at line 73 of file filters.h. Referenced by BiQuad(), getXML(), loadXML(), update(), and ~BiQuad().
