Basically what it says in the title; I have just started reading about these things and find noncausal filters pretty interesting in concept, but also they do not seem like they would have any advantage worth sacrificing real-time processing. Since "I have just started reading about these things" I feel as if I should make sure, and would also be interested in hearing: does anyone know if there are noncausal filters commonly used in practice? Why are they preferred? Thanks.
