\fIHdshrink\fP (1\-\s-1ESPS\s+1) has been changed to move comments 
from embedded headers only if a \fB-c\fP option is used.  
.np
A new generic header item has been added to \fIlpcana\fR output files:
\fInominal_frame_size\fR. It contains the target frame length for 
spectrum analysis; that is, the value specified by \fIlpc_frame_size\fR
in the parameter file. \fILpcana\fR now writes 0 for the value of the
\fIfrmlen\fR generic header item (it used to record \fIlpc_frame_size\fR).
These changes were made to make \fIlpcana\fR output compatible with the
new \fIme_spec\fR. 
.np
The following changes have been made to \fIrefcof\fR: fixed so that a
frame truncated (e.g., at end of file) is handled as full frame.  That
is, the optional window is applied as though the frame length is given
by the size of the truncated frame.  \fIPrefcof\fR (default parameter
file) - fixed to work properly with eparam (wrong default for analysis
method)
.np
A bug in \fIframe\fR was fixed that caused a problem with
\fIframe_len\fR == 0 and common was processed.
.np
\fIMcplay\fR was fixed so that the \fB-s\fR option handles
fractional seconds.  Some error messages were also improved.
.np
The manual page for \fIread_params(3\-ESPS)\fR was fixed to correctly
describe common processing.
.np
The library function \fIpc_to_lsf\fR was updated.   This has bug fixes.
.np
The programs \fIpwr\fR and \fIzcross\fR were updated
to correct some error messages.
.np
\fILpcsynt\fR now looks in the \fInominal_frame_size\fR generic header
to get information for synthesis; it used to look in \fIfrmlen\fR.  If
you want to synthesis from old lpcana output files, you need to add
the generic header item \fInominal_frame_size\fR.  This can be done
easily by using \fIaddgen\fP.
.np
The program \fIme_sgram\fR has been changed to have options consistent
with the new \fIsgram\fR program.  Also, it now allows non integer
step sizes.
.np
\fIlpcsynt\fR updated to fix a bug which only shows up on
Sun4 systems.
.np
The filter design program \fIwmse_filt\fR computes and stores in the
header of the output file the filter delay time, as \fIsample_delay\fR.
The programs \fIfilter\fR and \fIfft_filter\fR use this to correctly
compute the \fIstart_time\fR generic in the filtered output file.
The other filter design programs do not yet compute this and their
man pages have been changed to mention this.  
.np
Numerous minor bug fixes and documentation changes.  
.sh 1 "Waves+"
.lp
This release of ESPS fully supports the optional ESPS interactive graphics
interface, \fIwaves+\fR.   \fIWaves+\fR currently runs only on Sun3 and
Sun4 systems.   The \fIwaves+\fR distribution is in binary form
and includes the following programs:
.np
\fIwaves+\fR - this is the main program for \fIwaves+\fR.   It requires
the Suntools window environment to run.
.np
\fIspectrum\fR - this is an "attachment" for waves+.  It is an on-screen
spectrum analyzer.
.np
\fIlabel\fR - this is a time series labeling attachment for waves+.
.np
\fIformant\fR - computes formant frequencies, bandwidths and voicing
information.
.lp
The program \fIcmap\fP (1\-\s-1ESPS\s+1) didn't make it into this
release.  It will be available shortly.  
.lp
For information about \fIwaves\fP+ and ESPS, see the \fIwaves\fP+ man
page and the document "Waves+ Product Descriptions."  
.sh 2 "Installing Waves+"
.lp
See the ESPS installation instructions for details on installing
\fIwaves+\fR, but for the most part it is automatic when you install
this release of ESPS (assuming you bought \fIwaves+\fR!).   In the case
of Sun3, we supply two sets of binaries, one for the MC68881 floating
point chip and one for the Sun3 FPA board.  You should use the one that
matches your hardware.   The \fIwaves+\fR related programs and manual
pages get installed into the standard ESPS locations.  Some related
\fIwaves+\fR files, such as example parameter files and colormaps, get
put into the ESPS library in a subdirectory named waves (\fIeg.\fR
/usr/esps/lib/waves).
.sh 1 "Postscript Support"
.lp
Postscript support for the ESPS plot programs is provided by a program
that converts Tektronix plotting codes into Postscript.  This program is
public domain (tek2ps) and is included in the directory
\fIgeneral/pub/tek2ps\fR.   It is not installed by the installation
script.  You should compile it and install it as you see fit for your
system.  
.lp
The ESPS plot programs are all executed by a cover shell script
(\fIplotsd, plotspec\fR, etc).   The actual output of the plot programs
is an intermediate form that is piped to a program that turns it into
GPS or Tektronix codes.   For hardcopy plotting, we pipe the Tektronix
codes out to a laser printer capable of plotting these.   For a
Postscript laser printer, the output must be piped through tek2ps and
then spooled to the printer.  Edit the PLOTCOMMAND section of the
install script to produce a file with the correct command line for your
system (comment out all but one line in there).
.sh 1 "Installing 3.3"
.lp  
If you already have ESPS 3.2 installed, there are several options
about how to install 3.3.    If you want the target directory to remain
the same as before, simply read the 3.3 sources into 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
3.2.   Please read the 3.3 sources into a clean directory; if you want
it to be the same as you used for the 3.2 sources, then rename that
directory to something like esps.old first.  Don't read the tape
on top of the 3.2 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
3.2 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 many 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.
