Examples of jm.audio.synth.Filter

jm.audio.synth.Filter
Chebyshev filters are a recursive or IIR (infinite impulse response) filter. * They provide a fast mechanism for seperating frequencies using a mathamatical process known as a z-transform. This implementation is based on the Chebyshev filter design in Steven W.Smith's excellent book "The Scientist and Engineer's Guide to Digital Signal Processing". Band pass and resonant filters can be created by combining law and high pass filters. @author Andrew Sorensen @version 1.0, Sun Feb 25 18:42:51 2001

     * Initialisation method used to build the objects that
     * this instrument will use and specify thier interconnections.
