## Detailed Description

### template<typename FloatType>
struct dsp::FilterDesign< FloatType >::IIRPolyphaseAllpassStructure

The structure returned by the function designIIRLowpassHalfBandPolyphaseAllpassMethod.

The two first members of this structure directPath and delayedPath are arrays of IIR::Coefficients, made of polyphase second order allpass filters and an additional delay in the second array, that can be used in cascaded filters processed in two parallel paths, which must be summed at the end to get the high order efficient low-pass filtering. The last member is an array with the useful parameters for simulating the structure using any custom processing function.
