filters is a collection of Pure Data external filter objects based on Mike Moser-Booth's [filtercoeff.mmb~] and [biquad.mmb~] abstractions, translated in C. Instead of the [biquad.mmb~] abstraction, the proposed use of [fexpr~] is used in the code.
The library includes: [lowPass~] [highPass~] [bandPass~] [allPass~] [resonant~] [lowShelf~] [highShelf~] [peakNotch~]
Help patches are included. The help patches use the [spectrum.mmb~] abstraction for spectrum projection, as this is used in [filtercoeff.mmb~]'s abstraction help patch.
