A Database for the Acoustic Study of Male Bel Canto [a]

All acoustic analyses in this study were performed using the Praat software to ensure data accuracy and reproducibility. The sound samples used and their corresponding acoustic parameters are provided in the supplementary materials.
For ease of data management and reference, all samples were assigned a unified coding system. Samples numbered 1-16 correspond to those directly cited in the main text of the paper. As the total number of samples involved in the analysis exceeds 30, the remaining samples are sequentially numbered starting from 17.
Furthermore, all original audio files have been submitted as supplementary materials. A strict one-to-one correspondence has been established between the audio files and the sample codes in the dataset, ensuring an accurate match between the data and the audio. This facilitates cross-validation and in-depth analysis by readers, peers, and experts.

本研究中的所有声学分析均通过Praat软件完成，以保障数据的准确性与可复现性。本研究使用的声音样本及其对应的声学参数，均已收录于补充材料中。
为便于数据管理与查阅，所有样本均采用统一编码体系进行标识。编号1至16的样本，与论文正文中直接引用的样本一一对应。由于本次分析涉及的样本总数超过30，剩余样本将从17号开始依次编号。
此外，所有原始音频文件均已作为补充材料提交。本数据集内的音频文件与样本编码之间已建立严格的一一对应关系，确保数据与音频可精准匹配，此举便于读者、同行及专家开展交叉验证与深入分析。
