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 1.0<br>23 september 2013 Collected by Luis J.

本数据集包含约1500个波形音频（WAV）文件，采集于2003至2004年间波多黎各的多处保护林夜间环境。
数据采用自动化数字录音系统采集，该系统由以下设备组成：加利福尼亚州Creative Labs, Inc.出品的Nomad Jukebox 3数字播放录音机（型号DAP-HD0003）、新泽西州The Sound Professionals, Inc.出品的便携式前置放大器（型号SP-PREAMP），以及加利福尼亚州Sony Electronics Inc.出品的驻极体电容麦克风（型号ECM-MS908C）。麦克风安装于距地面约1米处。
该系统由保加利亚普罗夫迪夫Olimex Ltd.出品的微控制器（型号MSP430-P-1121M）控制，可触发录音机每30分钟录制1分钟音频。每个采样文件以WAV格式存储，采样率为48 kHz。
数据集按采集站点划分，每个站点拆分为多个压缩包以控制最终ZIP文件的大小。例如Site01-1.zip为站点1的第一部分压缩包，Site01-2.zip为站点1的第二部分压缩包，依此类推。
其中，sites.csv文件包含各采集站点的相关数据，data.csv文件包含对应站点内所有文件的元数据。每个ZIP压缩包的大小介于110 MB至230 MB之间。
