\fBRelease Notes for \fIwaves\fP+ Version 1.1\fR

Document version 1.3, 2/17/89
.sp 3
.lp
This document describes the changes from \fIwaves\fP+ Version 1.0 to 
Version 1.1, as well as known problems with 1.1.
.uh "Bug Fixes"
.np
Manual editing by "modify formants" now works for general ESPS FEA files,
as well as SIGnal .fb files, overlaid on spectrograms.
.np
The fixed-allocation limit on the total length of identifiers in a SIGnal
header has been removed.  Previously, reading a FEA file with too many
components would cause a core dump.
.np
The spacing and numbering of tick marks in spectrogram reticles are now
intelligently chosen.  A couple of bugs have been corrected that could
cause up to 2 pixels inaccuracy in placement of ticks along the vertical
axis.
.np
Insert_file in ESPS files now keeps the proper history in the headers.
.np
A bug has been fixed that caused bad headers to be written on ESPS
spectrograms done with the AT&T DSP32 board.  This bug prevented doing
certain cut and paste operations on such files, or using the spectrum
program to display slices from them.
.np
There no longer occurs a certain spurious error message that used to occur
when ESPS FEA_SPEC files were written.
.np
A bug has been fixed that prevented the use of the "activate" mechanism from
selecting the tracks to be displayed from FEA files overlaid on spectrograms.
.np
A bug has been fixed that could cause core dumps during reading of
multidimensional SIGnal files of types other than CHAR (bug fix from
AT&T).
.uh "Other Changes"
.np
Dithered spectrograms are now painted while the dithering is being
done (relevant for monochrome monitors).  
.np
A more complete history of delete_segment operations on ESPS files is now
kept in the header comments and the start_time and end_time header items.
.np
The COS4 and HANNING window types are now supported for waves+ spectrograms
computed with the external \fIsgram\fP (1\-\s-1ESPS\s+1) program.
.uh "Known Problems"
.np
\fIWaves\fP+ and its attachments sometimes look for files in ESPS/lib
instead of ESPS/lib/waves.  This is always harmless.  In specific
cases, you might want to put a copy of the relevant file into
ESPS/lib.
