Bat vs. Non-Bat Analysis Modes
Kaleidoscope has several settings and parameters that are specific to
past and present conventions for recording bats (e.g. time expansion) that are
not suitable for the conventions used to analyze other kinds of recordings.
The first time you launch this version of Kaleidoscope, or after setting
defaults, you will be asked to choose either "Bats" or
"Non-bats" as your preferred analysis mode. You can also change
your preference at any time using the control at the bottom of the control
panel. The control affects the analysis frequency and time ranges as
specified on the "Filter" tab as well as the meaning of the
"Auto" time expansion settings.
New Bats of North America 3.1.0 bat classifier
This is largely based on the 3.0.0 classifier except for removing one
weak cluster for MYSO to reduce MYSO false positives. Also modified
per-state default species lists by adding LACI, LANO, MYCA and MYYU to
Alaska and MYCI to Arizona.
Fix thresholds for sensitive/accurate settings
The "Balanced" and "More Accurate" settings were
not using the correct thresholds resulting in many fewer classifications
for several species. This has been corrected with 3.0.0 and newer classifiers
at this 3.1.0 release. (Older classifiers will produce the same results as
before for backward compatibility). In general, there should be little
difference between these settings except for a few species that tend
to contribute the greatest to false positive errors.
Fixed missing MYNA from licensed UK bat classifier list
Add ZC file editing
For power users, ZC files may contain "hidden" dots which are
not displayed or analyzed by default. In "Advanced Settings" in the
viewer, you can change your preference to show or hide these dots (they are
hidden by default).
Additionally, you can select dots and right-click in the selection to pop up
a menu with "Turn off dots" to hide the dots in the selected time
range.
Revision to idsummary.csv output format
Columns are now produced for all enabled classifiers, not just
classifiers with detections. This will help confirm which classifiers
were selected to produce a given set of outputs for better traceability.
Analysis window frequency axis now tracks spectrogram
The zoom and scroll of the analysis window frequency axis will now
follow the spectrogram making it easier to zoom in on a portion of the
frequency bandwidth for more detailed analysis.
Support for new .zc file extensions
AnalookW files can now use .zc file extensions.
Fix scan crash
Fix a bug in which file in the input directory containing no file
extension or a file extension with fewer than three characters could cause
a crash.
Fix viewer crashes
A few problems causing the viewer to crash have been fixed. These
include opening a triggered WAC file with no triggers, or opening large
files where analysis produces more than 32,768 divided zero-crossings.
Fix ZC output encoding
When converting to zero crossing files, there was a bug in the encoding
of long time period that could affect the accuracy of TBC measurements.
Fix incorrect spectrogram color
There was a bug in the color calculations in the spectrogram that could
cause subtle artifacts on the display
Fix width of frequency axis
The frequency axis ruler was too narrow to correctly display frequency
information.
Fix possible hang in noise analysis module when calculating SEL
