Figure 6From: Vocal communication in a complex multi-level society: constrained acoustic structure and flexible call usage in Guinea baboonsSpectrogram of a female Guinea baboon call. Five out of the nine call parameters used in the acoustic analyses are indicated in the spectrogram. White circles mark the DFA 2 (Fast Fourier transform-length 1024-points, Hann window, overlap 97.75%, time resolution 3.2 ms).Back to article page
