SFS Release 4/Windows
=====================

This directory contains binaries and some sources for the 
Speech Filing System version 4 for Windows.

File patterns are as follows:

sfs-4*.exe
	Self-installing executable for SFS.  Download
	(binary mode) into a temporary directory and run to
	install SFS on Windows computers.
sfs4*s1.zip
	ZIP archive of C program sources for library and essential
	utilities of SFS 4.  Includes makefiles for various
	platforms (many rather old).
sfs4*s2.zip
	ZIP archive of C program sources for most signal processing
	utilities of SFS 4.  Includes makefiles for various
	platforms (many rather old).
sfsmatlab1*.zip
	ZIP archive of SFS/MATLAB API: plug-in components to
	allow MATLAB program to access SFS files.  (This is now
	also a part of the main SFS distribution)

Read the installation notes provided for further information.

Introduction

SFS provides a computing environment for conducting research into 
the nature of speech. It comprises software tools; special file 
and data formats; subroutine libraries for I/O, signal processing 
and graphics; use and documentation standards; and special 
programming languages. It performs standard operations such as 
acquisition, replay, display and labelling, spectrographic and 
formant analysis and fundamental frequency estimation. It runs 
under Windows and Unix. SFS may be used and copied without charge 
although the copyright is retained by Mark Huckvale and University 
College London. SFS is supplied as is with no warranty or support.
