Rana sierrae annotated aquatic soundscapes (2022)

Rana sierrae (the Sierra Nevada yellow-legged frog) is an endangered species residing in high-elevation lakes in the Sierra Nevada mountains. The species is highly aquatic and, unlike most amphibians, primarily vocalizes while underwater. As a result, its vocalizations have rarely been recorded and its vocal repertoire is not well studied.
This dataset contains an annotated set of underwater soundscape recordings containing 1236 annotations of R. sierrae vocalizations. We annotated five distinct vocalization types of R. sierrae, only two of which have been previously documented for this species. Besides the calls of R. sierrae, these audio recordings also con..., The audio in this dataset is a set of 672 10-second audio files recorded at a spacing of 15 minutes over the course of 7 days on a single underwater audio recorder. The recorder, an AudioMoth version 1.2.0 in an underwater case, was deployed approximately 0.5 m from the shoreline, on the bottom of a lake in the Sierra Nevada in which R. sierrae breed and overwinter. 
The annotations of the five call types correspond to the descriptions in the associated manuscript:
A primary vocalization \"meow\" described in Vredenburg et al 2007
B stuttered vocalization, also described in Vredenburg et al 2007
C chuck, double/triple chuck calls
D short downward single note
E frequency-modulated call
X: could not determine if sound is R. sierrae or not; these were excluded from training and validation of the CNN in the manuscript
Files were annotated by Sam Lapp using Raven Pro with closed-back headphones while viewing spectrogram. Only calls that could both be heard and seen on spectrogram were annotate..., Audio files are provided in .mp3 format and are compatible with any program that supports this format. For instance, audio can be played and viewed as a spectrogram in the free Audacity software. Annotation files are provided in two formats:
(1) Raven annotation tables, which can be opened along with audio files in Raven Lite (free) or Raven Pro (paid) software to view, create, and manipulate annotation boxes on spectrograms. Note that even without Raven Lite / Pro, the annotation files can be loaded, explored, and manipulated using the free and open-source python package OpenSoundscape.
(2) A .csv file containing a table of 0/1 (present/absent, also known as \"one-hot\") labels for each call type for 2-second audio segments. This file can be opened with text or table editors, or loaded into Python using the pandas package., # Rana sierrae annotated soundscape recordings

## Data and file structure

This dataset contains audio files annotated in Raven Pro for Rana sierrae vocalization types. Frequency-time boxes were drawn around all sounds identifiable as vocalizations of Rana sierrae. Five vocalization types are annotated, and are described in the associated manuscript. In total, the dataset contains 1236 annotations of Rana sierrae vocalizations. Other sounds in the aquatic soundscape include stri...
