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本数据集收录单声道（通道数=1）、时长10秒的声音文件，均为直接安装于蝙蝠体表的麦克风采集的回声定位脉冲信号，采集对象为单独飞行或4只个体集群飞行的蝙蝠。数据通过高速数据采集卡完成数字化处理，该采集卡为美国国家仪器（National Instruments）型号NI PXI-6358，产自日本东京，采样精度16位，采样频率fs=500kHz。文件命名规则如下：batID_飞行状态.bin
