Kaleidoscope 3.1.0 Release Notes:

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
