Comparison of methods for rhythm analysis of complex animals’ acoustic signals
Fig 5
Individual Beat Clusters in C. perspicillata pups confirm the results of other methods: Exact beat frequencies as analyzed with the three different methods are shown with clusters in the data.
One individual is depicted per column, all exact beat frequencies found are shown as dots. Depicted in red are the sequences falling into the largest cluster of sequences sharing a similar beat. Percentages at the bottom indicate the percentage of sequences per individual in the largest cluster. (a) Exact beat frequencies and individual clusters as obtained by the GAT approach. (b) Exact beat frequencies and individual clusters as obtained by the FFT method. (c) Exact beat frequencies and individual clusters as obtained by IOI analysis.
