                      Entropic Signal Processing System (ESPS)

ESPS is a UNIX-based signal processing software package from Entropic
Speech, Inc.  (ESI), currently available for Sun 3, Masscomp, and 
Convex computers.  Other ports are underway.  Unique features of ESPS
include systematic record keeping, ease of extension, and ease of
cooperation among resources from different vendors on the same local
network.

Approximately 75 user-level programs (called from the UNIX shell) 
support spectrum analysis, filter design, filtering, scalar and vector
quantization, pattern classification, signal editing, file editing,
record selection, plotting, etc.  A library of more than 200 functions
supports the modification of existing programs and the development of
new programs.

ESPS is based on a well-documented, open architecture that allows easy
extensions of ESPS file headers and file types (including the creation
of new file types) in such a way that the extensions are supported
automatically by standard ESPS plotting, printing, editing, statistics, 
pattern classification, and database programs.

List prices are $5,000-$20,000.  Academic discount is 50%.  Sources
are available.
