Fig. 6. The calling song of Teleogryllus oceanicus taken from a recording made in the field at Carnarvon, Western Australia. (A) Oscillogram of one song echeme, showing the chirp of four pulses and a trill of paired pulses. (B) Oscillograms of the third pulse of the chirp shown in A and the first and second of the first of the pair of pulses of the trill shown in A. (C) Graph of the cycle-by-cycle frequency of the four pulses of the chirp shown in A (black lines) and the first (blue line) and second (red line) pulse of the paired pulses of the trill shown in A. The frequency against time plots have been superimposed by eye and the starts (S1 and S2) and ends (E1 and E2) of the paired pulses in the trill are shown by vertical, broken lines. Note that these data suggest that the 1st and 2nd of the paired pulses of the trill are produced by different parts of the file.
