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. Other Features: + UNIX tools approach, including UNIX pipes + disciplined software engineering + information hiding approach + full LINT library provided + ESPS library performs extensive error checking + complete, on-line manual + conversion programs for ILS, Masscomp LWB, ASCII, and binary sampled data files + direct analog I/O available + data plots, scatter plots, histograms + mouse support for signal editing Contact: Entropic Processing, Inc.
