Fig. 7: Analytical challenges of the AnuraSet.
From: A dataset for benchmarking Neotropical anuran calls identification in passive acoustic monitoring
(a) spectrogram showing eight different species that were recorded calling in less than eight seconds, highlighting the degree of co-occurrences, call overlap, and fine-grained identification; (b) spectrogram showing a dense chorus with a low signal-to-noise ratio and high sound masking. (c) spectrogram showing the richness and co-occurrence of sounds from different taxa (silhouettes from bottom to top depicting frogs, birds, and orthopterans, respectively).
