Detailed Description

template<typename SampleType>
struct juce::dsp::Oversampling2TimesEquirippleFIR< SampleType >

Oversampling stage class performing 2 times oversampling using the Filter Design FIR Equiripple method.

The resulting filter is linear phase, symmetric, and has every two samples but the middle one equal to zero, leading to specific processing optimizations.
