Detailed Description

template<typename SampleType>
struct juce::dsp::Oversampling2TimesPolyphaseIIR< SampleType >

Oversampling stage class performing 2 times oversampling using the Filter Design IIR Polyphase Allpass Cascaded method. The resulting filter is minimum phase, and provided with a method to get the exact resulting latency.
