Entropic Processing, Inc. has  been  developing  a  signal  processing
package  --  Entropic  Signal Processing System (ESPS) -- and we'll be
releasing it soon.  We are now looking  for  beta  test  sites.   Beta
sites  will  receive a full source distribution without any obligation
to buy, but we do expect the sites to have a serious interest  in  the
product.  Pricing has not been determined yet, but probably will be in
the $12K-$15K range for full source and around $5K for a full  binary.
Universities  will  get  a  substantial discount (probably 50%).  Beta
sites that elect to purchase will get a substantial discount from  the
applicable base price (probably 30%).

If you're interested, let us know. Also, we'll have a booth at ICASSP87;
if you're going and want to chat, please stop by.

A little info about Entropic:  it was started about  3  years  ago  by
John  Burg  to  pursue commercial applications of advanced signal pro-
cessing methods.  In addition to ESPS, we  have  developed  a  4800bps
speech coder.

Here is a technical description of ESPS:


             Entropic Signal Processing System (ESPS)


ESPS supports signal processing both with a set of  applications  pro-
grams  and  with  a  programming environment.  ESPS is well suited for
work in speech processing, image processing, seismic analysis, commun-
ications,  medical  signal processing, etc.  A set of approximately 50
user-level programs (called from the UNIX shell) support  analog  I/O,
spectrum  analysis,  filtering,  scalar quantization, vector quantiza-
tion, pattern classification, signal editing, file editing,  plotting,
etc.   ESPS also includes a library of over 130 functions that support
the modification of existing programs and the development of new  pro-
grams.   The  ESPS library contains functions that perform signal pro-
cessing primitives as well as functions that support the creation  and
manipulation of ESPS files.  ESPS provides 5 basic file types plus the
ability to modify these file types and to create new file types.  ESPS
file  headers  maintain  a complete history of the processing that has
been performed on the data contained in the file.

Key Features:

  o  applications programs plus a software toolkit
      o  direct support for traditional operations
      o  supports rapid development of new operations

  o  UNIX tools approach, including pipes

  o  ESPS file headers maintain a complete data processing history

  o  ESPS header fields and record fields are referenced by name

  o  easy manipulation of header and data record contents

  o  ESPS file editor

  o  interactive select(1) program treats ESPS files as a database

  o  user-extensions to ESPS files (doesn't require source license)
      o  easy to modify existing file types
      o  easy to create new file types
      o  extensions supported by ESPS plotting, printing,
         editing, and data base programs

  o  disciplined software engineering
      o  information hiding approach
      o  full LINT library provided
      o  ESPS library performs extensive error checking

  o  complete, on-line manual

  o  conversion programs for ILS sampled-data files

  o  conversion programs for MASSCOMP LWB files

  o  conversion programs for ASCII data

  o  direct analog I/O available

  o  subroutines can be written in C or FORTRAN

  o  data plots, scatter plots, histograms

  o  plot programs produce MASSCOMP GPS or Tektronix output

  o  mouse support for signal editing

  o  can run under wi

  o  X-Windows interface under development

  o  laserprinter support

Prerequisites:

    if on-screen plots are desired, any MASSCOMP graphics terminal
    or any  Tektronix 40XX or 41XX terminal; if analog I/O is desired,
    MASSCOMP data acquisition hardware
