Hi All, Technically this has all been on list before, just now it is in a coherent patch set. Introduces low pass filter controls and description via 3db point. JohnLM suggested a whole load more stuff that we might want to know about filters. Whilst I am in favour of adding these at somepoint I think it should be as and when we have a user. I believe the naming here allows space for all the other things that have been suggested. Thanks. v1->v2 Added documentation.
