Time hierarchy: a ′file′ is sliced into ′sections′ where you identify ′calls′ which all
contain at least one ′pulse′.
Interactive measurements are saved as spreadsheet-readable files (Excel). MouseTool
measurements are logged into TextPad and saved as a text file.
Go to File-Open, choose a sound file and slice it in sections.
Locate calls with the buttons manual, auto or sample.
Manual: click at the beginning and at the end of a call, then click Manual.
Auto: go to Options-Section to set parameters for call recognition, then click Auto.
Sample: click at the beginning and at the end of a call and once at the beginning of the next call.
Do the same for finding pulses in the calls (no manual option).
To add pulses manually: click on each side of it (two green bars) and click Auto.
Right-click (Ctrl+click in the Mac) to access the tools.
Measure: click or shift-click to measure. Right-click to log to TextPad.
ClickPlot: click on oscillograms to plot in bottom graphs. Shift-click to define segment.
Filter: right-click on the spectrogram and choose Filter (click: low freq, shift-click: high freq)
Freq tracking: like filter but defines limits to track a harmonic along the call.
Right-click on a plot to play it.
Right-click, Play Custom for altered playback. Find settings at Options - Audio.
Batch graphing: File - Export Graphs, edit your figure, click Refresh to update the data.
Go to Tools - Tuning Curve, open an example custom filter and apply it to your sound file ′on the fly′.
As you get calls recognized, click the CCA button, and then go to Tools - Cross Correlation to analyze overlap.
If your sound file has a sequence of known amplitude, go to Tools - Amplitude Calibration.
To envision an acoustic scenario quantitatively, go to Tools - Sound Math.
Do not forget
To know what you are doing, read the manual and some books on acoustics!!!
