Audio Visual Index data for 'Species identification apps increase acoustic detections in bird citizen science data'

File details the number of audio, photo and video recordings in Bird Conservation Region 23 (BCR23) used to calculate the Audio-Visual Index (AVI) used in 'Species identification apps increase acoustic detections in bird citizen science data'. The AVI itself is calculated as AVI = audio/(audio + photo), which we then scale for use in the paper. Details can be found in the related GitHub repository.本文件详细记录了用于计算刊载于《鸟类公民科学数据中物种识别应用提升声学检测效能》一文的视听指数（Audio-Visual Index，AVI）所需的鸟类保护区域23（Bird Conservation Region 23，BCR23）内的音频、照片与视频录制文件数量。该视听指数的计算公式为AVI = 音频数/(音频数 + 照片数)，随后我们对该指数进行了缩放处理以适配本文的研究应用。相关细节可查阅本研究关联的GitHub仓库。
