SoundFile

Sound files (number of channels = 1; data length = 10 seconds) of echolocation pulses recorded with microphones mounted directly on bats flying alone or in groups of four individuals. The data were digitized using a high-speed data-acquisition card (National Instruments, Model NI PXI-6358, Tokyo, Japan, 16 bit, fs = 500 kHz). File names are as below. "batID"_"flight condition".bin

本数据集包含声道数为1、单段时长10秒的声音文件，内容为直接安装在单独飞行或4只个体集群飞行的蝙蝠体表的麦克风所录制的回声定位脉冲。数据通过高速数据采集卡（美国国家仪器公司National Instruments，型号NI PXI-6358，产地日本东京，16位量化，采样率fs=500 kHz）完成数字化处理。文件命名格式为：batID_飞行状态.bin。
