filter

Filter is a set of MSP and Jitter IIR filter externals for the Butterworth, Chebyshev Type-I/Type-II, elliptic, Legendre, and Bessel filter topologies. The package also includes one-pole filter with two outlets for simultaneous lowpass and highpass outputs as well as a DC blocker.

Please refer to part 3 and part 4 of the Demystifying Digital Filters series which discuss the inner workings of the IIR filter objects contained in this package.
