The purpose of this tutorial is to introduce and expose audio engineers to additional filters that have interesting properties but are not as commonly known to our community.In this tutorialWe take a deeper look at allpass filters – where phase (instead of frequency shaping) is used as a manipulating toolWe take a closer look at real-time zero-phase IIR filtering techniquesFinally, we look at multi-rate sampling systems, where in addition to polyphase FIR filters we also look at polyphase IIR approaches
