Abstract: Vocalizations are the primary communication signals of anurans, and quantifying acoustic parameters provides essential data for bioacoustic research. However, a systematic acoustic characteristics dataset for anurans in East China is currently lacking. By comprehensively reviewing public audio platforms, published acoustic literature, and online amphibian databases, we constructed an acoustic characteristics dataset covering 94 species of 30 genera and 8 families of anurans in East China. The dataset records taxonomic information, provincial distribution, vocal sac type, and call structure for each species, documents the recording locality of each audio file corresponding to each species, and extracts quantitative parameters for each call unit, including duration, dominant frequency, bandwidth, spectral centroid, spectral skewness, spectral kurtosis, and harmonic-to-noise ratio. In addition, representative sound figures (oscillograms and spectrograms) are provided for 94 species. This dataset will provide fundamental data support for comparative studies of species acoustic characteristics, adaptive evolution analysis of call traits, and regional passive acoustic monitoring.
