\fILpcana\fP updated;  default values for min_pp, lpc_frame_size, and
lpc_order added.
.np
Changed parameter file handling (symbols.c) so that if a parameter is to
be prompted for (by using ?= in parameter file) and standard input is
not the user's terminal (the data file is going in on standard input,
for example), the default value is taken instead.  A warning is printed
in this case.
.np
Added complex sqrt to library; manual page complex.3 updated.
.np
\fIFea_stat\fP has been updated to operate on other than just FEA_ANA files.
.np
Added support for local library functions and local programs.  A
skeleton local directory is provided.
.np
New library function \fIstsolv(3)\fR.
.sh 2 "Other Changes"
.np
Fixed the man page for \fIpspsdiff\fP to mention a problem with
options (a space is required around them).
.np
Fixed the man page for \fIwmse_filt\fP to clarify the prompt mode.
.np
Fixed \fIfea_edit\fP to not drop the refer file.
.np
Changed man page for \fIcopysps\fP to mention segment labeled and
tags.
.np
Fixed problem in install script that was causing header files
to be installed mode 440 regardless of what was specified in
the install script.
.np
Added fldrangesw.c to library and updated man page for rangeswtch.3.
.np
\fISpectrans\fP fixed to save correct file as source file.
.np
\fIvq\fP:  Some header items and history were not being written in
checkpoint file.  \fIvqdes\fP and \fIvqdesasc\fP man page description of -i
option was wrong.  Also fixed SEE ALSO section.
.np
Fixed makefile to \fIcross_cor\fP to install default parameter file.
.np
Fixed fmatalloc.3 
arr_alloc.3, calloc.3, malloc.3, getfeasiz.3, savestring.3, 
skiprec.3, symtype.3 manual pages. (Minor typos or reference problems)
Updated fea.5t man page and copyheader.3 man page.
Updated writeheader.3 man page.
getsdorec.3 manual page updated.
.np
Fixed \fIlpcana\fP so that it fills in "refer" with the input file name.
.np
Fixed \fIwmse_filt\fP. Filter type changed to FILT_ARB and
samp_freq added as generic.
.np
Updated \fIfiltspec\fP to correct an error message.
.np
Fixed \fIpsps\fP so that it displays filter type and method
correctly, instead of just displaying code values.  It also now accepts
a range of tags with the -t option.
.np
Fixed putsym_f (it wasn't updating correctly).
Added putsym_f to lint library.
.np
Fixed get_cmd_line(3\-ESPS):  if called more than once, it would
append the command line to the buffer already containing the
command line.
.np
\fIMake_sd\fP usage statement fixed.
.np
Fixed \fIselect\fP to clear the record before copying from input
to buffer.  This way, if all fields are not being copied, the
others will be zero.
.np
Fixed \fIselect\fP != operator.  Didn't work on coded and strings.
.np
\fIFind_ep\fP man page updated.
.np
\fIHis\fP updated (and man page).  Default number of bins is now 64.
.np
Updated \fIfiltspec\fP and test script. Does computations in doubles
instead of floats.
.np
Added a number of Convex fixes to install script.
.np
Fixed bug in headers.c relating to zapping of reference
headers in write_header.
.np
Fixed parameter processing (symbols.c) so that verbose message doesn't come
out for prompted symbols, even if you get them twice. 
.np
In \fIaplot\fR two axis-label bugs were fixed:  0.0 sometimes
appeared as a small floating-point number with lots of digits;
the last label was sometimes omitted.
.np
Updated \fIfft_filter\fR: The sampling frequency in the input sampled 
data file is checked against the filter's design sampling frequency. 
A warning is issued if they are different.
Also fixed a problem with getting the coefficients from the
parameter file, instead of a file file and
the sample freq wasn't going into the header.
.np
\fIScatplot\fR: The changes were to correct axis-labeling bugs:
0 sometimes appeared as a small nonzero floating-point number,
and the last axis label was sometimes omitted.  The changes in
scatplot.c were a major revision.  The first input file no
longer plays a special role in determining range and scaling.
Automatic scaling is now based on the maximum and minimum over
all records of all files of the x or y coordinate.  Any input
file can be stdin.  The -r option can be repeated to specify
different ranges for different files.  Default is to plot all
records from allfiles.
.np
\fIMlplot\fR and \fIgenplot\fR changed to pay attention to environment
variable BUNDLE, like other plot programs.
.np
Added record number as comment in \fIfea_edit\fR ascii file.
.np
New library function \fIcopy_genhd(3)\fR for copying generic header
items from one header to another.
.np
Various ass-sordid bugs fixed.  
.sh 1 "Installing 3.2"
.lp  
If you already have ESPS 3.1 installed, there are several options
about how to install 3.2.    If you want the target directory to remain
the same as before, simply read the 3.2 sources any any directory you
desire and follow the installation instructions.  Set the target
directory path in the installation script to be the same as you used for
3.1.   Please read the 3.2 sources into a clean directory; if you want
it to be the same as you used for the 3.1 sources, then rename that
directory to something like esps.old first.  Don't read the tape
over top of the 3.1 sources, some names have changed and things might
get confused.  
.lp
If you are short on file space, then you should probably delete the old
3.1 sources and binaries first.  If you reinstall over the old version a
copy of all binaries will be kept in the bin/old directory.  This will
take several megabytes.
.sh 1 "Graphics on Sun Systems"
.lp
All of the ESPS plot programs produce an intermediate plot stream
output, which is then processed into Unix GPS format.  If the plot is to
the displayed on the Sun screen, this is then processed by the ESPS
program \fImcd\fR, which runs under Suntools.  \fIMcd\fR will create a
window and display the plot in that window.   The window with the plot
can be moved, resized, or reduced to an icon.   It is removed when no
longer needed by using the \fBQUIT\fR item on the menu pulled down by
clicking the mouse on the title bar (just like all tools under
Suntools).
.lp
Do not write any programs which depend upon the intermediate output of
our plot programs.  This will probably change in a future release.
.sh 1 "Hardcopy of Graphics"
.lp
The ESPS plot programs can produce output for the Imagen laser printer
using its Tektronix emulation mode.   If you have another type of
printer or plotter that can plot tektronix plots streams then you should
be able to use it as we use the Imagen.  If you use a postscript based
printer (such as the Apple LaserWriter) we can supply a public domain
tektronix to postscript emulator.   Call us if you want it.
.lp
To adapt another type of plotter to the plot programs, look at the install
script under \fIesps_plot\fR.   Call us if you have
questions.   In the next major release, we are going to provide a better
way to specify the type of hardcopy plot device in the install script.
.sh 1 "Data Acquisition on Suns"
.lp
This version of ESPS does not directly support data acquisition (speech
input and output) on Suns, since there is no standard speech hardware
used by Suns.   This package does include the source code to the speech
input and output programs used on ESPS Masscomp systems.   If you have
data acquisition hardware, you might be able to modify these programs
for your hardware.  The speech input program is called \fImcplay\fR and
the speech output program is called \fImcrecord\fR.
.lp
If you have another means of data acquisition that results in a binary
file (of 16 bit integer data) you can use the ESPS program \fIbtosps\fR
to turn that file into an ESPS sampled data file.   You can also use
\fItestsd\fR with the -a option to produce an ESPS sampled data file
from an ascii file.
.lp
The ESPS program \fIbhd\fR can be used to remove the ESPS header and
leave behind just the binary data from an ESPS data file.   In the case
of sampled data files, you can convert to the correct data type with
\fIcopysd\fR first.
