Figure 4 from: Hershberger WL (2021) Substrate-borne vibrations used during acoustic communication and the existence of courtship songs in some species of the genus Anaxipha (Saussure) (Orthoptera: Trigonidiidae: Trigonidiinae).

Figure 4 Oscillograms of the calling and courtship songs of the four species of Anaxipha. A1.A. exigua calling song; A2.A. exigua courtship song; B1.A. tinnulacita calling song; B2.A. tinnulacita courtship song; C1.A. tinnulenta calling song; C2.A. tinnulenta courtship song; D1.A. thomasi calling song; D2.A. thomasi courtship song. All audio files were normalized to -3 dBFS for comparison. Y-axis represents amplitude and is analogous to dBFS (full scale).
