EIN KLEINER FILTER COMPILER
             version 2.0

ein is a simple interface that makes it  easy  to  implement digital  filters  process sounds and tinker with signal processing algorithms. . The results are converted  to  sound,  and  analyzed  using  the discrete  Fourier transform.  The interface was developed by Paul Lansky, using the  filter  compiler  designed  by  Ken Steiglitz  (see  his  ``Ein Kleiner Filter Compiler,'' Tech. Report CS-TR-279-90, Dept. of  Computer  Science,  Princeton Univ., Aug. 1990).   The syntax of ein scripts is basically a description of digital filter flow diagrams.   It is essentially a scratchpad for dsp and is not meant to be a production tool.
