• Added additional key shortcuts for many basic operations. See tabbed shortcut page on Help panel for info.

• New utility: D500x File Attributer for time stamping and adding SonoBat notes and attributes to files.

Version 2.9.4

• Improved sonogram display attributes. Automatically adjust sonogram to optimize display for different file formats.

• Support for WavPack files. SonoBat can now open WavPack files without need to first convert them to wav files.

SonoBat 2.9.2 incorporates automated developed as part of the upcoming automated species classification of SonoBat 3.

            
• Automated standard view length selection, automated filtering, automated call trending, and automated call parameterization.

• SonoBat intelligent call trending (displayed in yellow) tracks calls through noise and echoes. Note how zero-cross analysis (shown in magenta dots below) can miss the lower amplitude end-of-call details in the presence of noise and echoes. Zero-cross analysis can only detect the strongest frequency component at any time and can miss call trends when other signals exceed the amplitude of the call component. Full-spectrum data enables SonoBat intelligent call trending to reliably track the time-frequency trend of the entire call.

Other enhancements with version 2.9:

• Improved discrimination logic to seek signals with tonal content, independent of signal strength.

• Improved Batch Scrubber logic to prevent scrubbing of low frequency calls.

• Enhanced and expanded parameter set.

• Call data spreadsheet now automatically writes with data headers.

• Preference panel setting for enabling analysis automatically upon standard view selection.

• Improved Batch Attributer to enable batch attributing without changing original filenames.

• Many other minor tweaks, fixes, and improvements.
