\fIwaves\fP+ Version 2.0b Release Notes
.sp
Document version: 1.11 2/25/91
.sh 1 "INTRODUCTION"
.lp
This document provides notes relevant to release 2.0b of \fIwaves\fP+.
Please read this document and the Installation Instructions completely
before installing this release.  This note documents changes to
\fIwaves\fP+ since the revision 1.2a.  
.lp
Note that there's an option (\fB-u\fP) on the program
\fIeversion\fP (1\-\s-1ESPS\s+1) that will display an on-line copy of
these release notes to any ESPS user.  This is a convenient way for
ESPS users to find out about the changes.
.sh 1 "CHANGES SINCE 2.0a AND 2.0b RELEASE"
.lp
All of the major changes in this release of \fIwaves+\fR are in the X Window
version, \fIxwaves+\fR.   The major change is that \fIxwaves+\fR is now
built under Version 2.0 of the XView toolkit.   This includes a number
of X Window related bug fixes from the previous version (XView 1.0.1).
This release also includes the first release of \fIxwaves+\fR for Convex
computers and Apollo (Domain 10.3).
.lp
Be sure to consult the \fIREADME\fR file in \fI/usr/esps/xview\fR for
the latest information on how to run \fIxwaves+\fR with different window
managers and servers.
.sh 2 "CHANGES SPECIFIC TO 2.0b"
.lp
The following bug fixes and changes have been made to \fIwaves+\fR
and/or \fIxwaves+\fR:
.np
At present, a FEA_SPEC file read by \fIwaves+\fR or \fIxwaves+\fR must have
SPTYP_DB as the value of its "spec_type" header item (though this will
eventually be generalized).  Because of a bug (a missing check), trying
to read a FEA_SPEC file with any other spec_type would cause a core
dump.
The check has been added, and the current behavior is to print a warning
message instead of dumping core.
.np
A problem has been fixed that caused
a few pixels to get cut off at the bottom
of a signal window.  This could it impossible to read the label and value
readout,
especially for the lowermost trace in a window with several traces.  
Also, a few extra pixels of extra margin have been eliminated at
the bottom and right of the window.
Finally, some unevenness has been eliminated in the spacing of the
labels and value readouts in multi-trace signal windows.
.np
Colormap handling in \fIxwaves+\fR, \fIxspectrum\fR, and \fIxlabel\fR 
has been revised to
use the CMS package introduced in OpenWindows version 2.0.
.np
The \fIxwaves+\fR control panel now has a "Pause" button that works like
the "pause" command in waves command scripts.  
Pushing it causes a running script
to stop, and pushing the "Continue" button causes the script to resume
execution.
.np
A kill window button has been added to the waveform menus in \fIxwaves+\fR.
This is needed for window managers that do not implement a frame menu
with a kill function.
.np
Bug fixes in \fIxlabel\fR: The left and middle mouse buttons
were playing segments of speech twice:  when released as well as when
pressed.  The cursor was not returning to its former position after
being
used to select a label from the menu.  Dismissing the label menu without
selecting a label would cause a mark to be set in the signal window with
no corresponding mark in the label window.
.np
Bug fix in \fIxspectrum\fR.  The mouse buttons were performing
their functions twice:  when released as well as when pressed.
.np
Whenever a waveform or spectrogram window is created or repainted, and
an attachment is running, \fIxwaves+\fR will instruct the attachment to
create or update its display for the object to which the window
belongs.  This implies in particular that if you start \fIxwaves+\fR, start
an attachment, and then bring up a waveform or spectrogram, the label
or spectrum window will appear immediately, rather than at a later
stage of the proceedings.
(This feature was present at one point in SunView waves+, but
was lost about a year and a half ago through an overzealous attempt 
to eliminate unnecessary repainting of some windows when other
windows were uncovered after being obscured.)
The change will be especially apparent with \fIxlabel\fR, which
responds to the instruction by repositioning and rescaling the label
window to align the marks in the label window with the marks in the
signal window (the most recently created signal window in the object
when there are more than one.)  The \fIxspectrum\fR attachment does not
reposition its window.  The \fIxlabel\fR attachment now does a better job of
maintaining alignment.  Previously the repositioning and rescaling
would be triggered by certain events, such as zooming or scrolling
operations, but resizing the signal window would destroy the
alignment.  Now resizing will also cause automatic realignment.  So
will simply refreshing the signal window.  Simply moving a signal
window can still break the alignment, but you can restore it by causing
a refresh.  If a signal window is at the bottom of the screen, the
label window may be positioned off the bottom of the screen.  If that
happens, just move the signal window up and cause a refresh.
.np
A bug has been fixed that used to cause incorrect positioning
of the label window under the olwm window manager.  Occasionally the
label
window would be drawn across the middle of the signal window rather than
beneath; the rest of the time, the frame at the top of the label window
would obscure a narrow strip at the bottom of the signal window.  Now
under olwm the top of the label window just touches the bottom of the
signal
window.  Under current twm, the horizontal alignment is correct, and
the top of the label window is separated from the bottom of the signal
window
by a narrow gap.
Window positioning is highly window-manager-dependent, and it is
impossible to guarantee correct positioning under all window managers.
.lp
The following changes have been made to \fIformant\fR
(1\-\s-1ESPS\s+1):
.np
A bug has been fixed relating to the \fB-R\fR option.
.np
A new option, \fB-M\fR has been added for passing in a constant rms
value.
.lp
The program \fImu2esps\fR (1\-\s-1ESPS\s+1) has been added to the
\fIwaves+\fR product distribution.  
.lp
The remainder of this release note describes changes since 1.2a.

.sh 1 "PROGRAMS IN THE RELEASE"
.lp
This Section lists the various programs that are part of the Version
2.0 release.  Naturally, the release includes the \fIwaves\fP+ program
itself.
.sh 2 "\fIwaves\fP+ Attachments"
.lp
The following \fIwaves\fP+ attachments are included: 
.sp .5
.nf
.ta 1.0i
  \fIspectrum\fP \-	interactive spectrum analysis
  \fIlabel\fP \-	interactive labeling 
  \fImarks\fP \-	interactive labelling of pre-defined events
.fi
.lp
The \fImarks\fP attachment is new with \fIwaves\fP+ Version 2.0, and 
is available only for Sunview; an X Windows version will be released
later.  
.sh 2 "Auxiliary Programs"
.lp
In previous releases, "Standalone \fIwaves\fP+" was distinguished from
"Basic \fIwaves\fP+" by the inclusion (in Standalone) of various ESPS
file conversion programs.  In Version 2.0, we have eliminated this
distinction so that \fIwaves\fP+ is always shipped with the file
conversion programs.  We have also added \fItestsd\fP and the new
program \fItofeasd\fP to the set of ESPS programs shipped, and we have
included a new program (\fIcmap\fP) to support the generation or
editing of \fIwaves\fP+ colormaps (in Version 2.0, \fIcmap\fP is only
available under Sunview; an X windows version will be released later).
The set now includes 18 file conversion and display programs, five
utilities (\fIeman\fP, \fIeversion\fP, \fIespsenv\fP, \fItestsd\fP,
\fIcmap\fP), two processing programs (\fIsgram\fP, \fIformant\fP), and
two license management programs (\fIwcheckout\fP, \fIwfree\fP).
Distributions for the SPARCstation I also include programs to record
and play by means of the built-in codec.  Here's the full list:
