Sounds of the Eleutherodactylus frog community from Puerto Rico

Data comprises about 1500 wav files recorded in several protected forests in Puerto Rico during the night. Between 2003 and 2004.
The data was recorded using an automated digital recording system that consisted of a Nomad Jukebox 3 digital player and recorder (Model DAP-HD0003, Creative Labs, Inc, California), a portable preamplifier (Model SP-PREAMP, The Sound Professionals, Inc., New Jersey) and an electret condenser microphone (Model ECM-MS908C, Sony Electronics Inc, California). The microphone was placed at approximately one meter from the ground. The system was controlled with a microcontroller (model MSP430-P- 1121M, Olimex Ltd., Plovdiv, Bulgaria), which triggered commands to the recorder to record 1 minute every 30 minutes. Each sample was stored as a .wav file using a sampling rate of 48 kHz.
The dataset is divided by site, each site is divided into multiple files to limit file size of the final zip files. Site01-1.zip is the first of Site 1, Site01-2.zip is the second of Site 1, etc. The file sites.csv contains the data for the sites where the data was collected. The file data.csv contains the metadata for all the files in that site. Each zip file is between 110 and 230 MB.
Version 1.023 september 2013

Updated on 23 october 2013: Added two csv files:
FrequencyRange_by_species_and_site_AllData.csv - contains the frequency range for each species at each site, by recording
FrequencyRange_by_species_and_site_Averages.csv - contains the average frequency range for each species at each site

本数据集汇聚了约1500个在波多黎各数个受保护森林中夜间录制的WAV格式音频文件。数据采集于2003年至2004年期间。录音设备为一套自动化数字录音系统，包括Creative Labs, Inc.生产的Nomad Jukebox 3数字播放及录音机（型号DAP-HD0003）、The Sound Professionals, Inc.便携式前置放大器（型号SP-PREAMP）以及Sony Electronics Inc的驻极体电容麦克风（型号ECM-MS908C）。麦克风距离地面约一米。该系统由Olimex Ltd.的微控制器（型号MSP430-P- 1121M）控制，每隔30分钟触发录音机记录1分钟的音频。每个样本均以48 kHz的采样率存储为WAV文件。数据集根据采集地点进行划分，每个地点的数据被分割成多个文件以限制最终ZIP文件的体积。Site01-1.zip为Site 1的第一个文件，Site01-2.zip为Site 1的第二个文件，以此类推。文件sites.csv包含了数据采集地点的信息，而文件data.csv则包含了该地点所有文件的元数据。每个ZIP文件的体积介于110至230 MB之间。版本1.023，发布于2013年9月。更新于2013年10月23日：新增了两个CSV文件：FrequencyRange_by_species_and_site_AllData.csv，记录了每个地点每个物种的频率范围；FrequencyRange_by_species_and_site_Averages.csv，记录了每个地点每个物种的平均频率范围。数据由Luis J.
