Character	Description
Call duration	Time from the beginning of the first note to the end of the last note of the call
Number of notes per call	Number of notes in the call
Rise time of the call	Time from the beginning of the call to the point of its maximum amplitude
Number of pulses per call	Number of pulses in the call
Type I note duration	Time from the beginning to the end of the long note
Number of pulses of the Type I note	Number of pulses of the long note
Rise time of the Type I note	Time from the beginning of Type I note to the point of its maximum amplitude
Type II note duration	Time from the beginning to the end of the short note
Number of pulses of the Type II note	Number of pulses of the short note
Distance between notes	Time between the end of one note and the beginning of the following note
Average of the dominant frequency call	Average frequency of the harmonic with the maximum energy at the beginning, middle and end of the call
Frequency bandwidth	The higher frequency at any point of the call minus the lowest frequency at any point of the call
Distance between pulses	Time from the highest amplitude peak of a pulse to the highest amplitude peak of the following pulse
