FIGURE 17. Calls A and B of Physalaemus signifer. Oscillograms (A, C–G, M, and O–P) and audiospectrograms (B, H–L, N, and Q–R). A single typical call A (A and B). Variant A calls with different envelopes and level of periodic amplitude modulation (C–L). Calls B (M–R). Horizontal scale bars have 0.1 s; vertical scale bars have 1 kHz. Filter bandwidth (Hz): 48.8 (I–H, N, and R); 50.7 (J); 69.0 (B); 55.2 (K); 42.3 (L and Q).
