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、时长10秒的声音文件，其内容为直接固定于单独飞行或4只集群飞行蝙蝠体表的麦克风所采集的回声定位脉冲（echolocation pulses）。数据通过高速数据采集卡（high-speed data-acquisition card）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，采样位数16 bit，采样频率fs=500 kHz。文件命名格式如下：「蝙蝠编号(batID)_飞行状态.bin」。
