C++ classes for designing high-order Butterworth IIR & equalization filters

A Java Library for Digital Signal Processing

Elegant Butterworth and Chebyshev filter implemented in C, with float/double precision support. Works well on many platforms. You can also use this package in C++ and bridge to many other languages for good performance.
