warbleR (version 1.1.0)

warbleR: warbleR: A package to streamline bioacoustic analysis

Description

warbleR is a package designed to streamline analysis of (bio)acoustic signals in R. This package allows users to collect open-access avian vocalizations data or input their own data into a workflow that facilitates spectrographic visualization and measurement of acoustic parameters in a batch process. The functions facilitate searching and downloading avian vocalizations from Xeno-Canto http://www.xeno-canto.org/, creating maps of Xeno-Canto recordings, converting .mp3 files to .wav files, checking .wav files, automatically detecting acoustic signals, selecting them manually, printing spectrograms of whole recordings or individual signals, measuring signal to noise ratio, cross-correlation and performing acoustic measurements.

Obtaining avian vocalization data

querxc: Download recordings and metadata from Xeno-Canto

xcmaps: Create maps to visualize the geographic spread of Xeno-Canto recordings

imp.syrinx: Importing Syrinx selections

imp.raven: Importing Raven selections

Managing sound files

mp32wav: Convert several .mp3 files in working directory to .wav format

checkwavs: Check whether .wav files can be read by subsequent functions

Streamlining analysis of acoustic signal structure in R

autodetec: Automatically detect start and end of acoustic signals

manualoc: Interactive spectrographic view to measure start and end of acoustic signals

autodetec: Automatic detection of acoustic signals based on ampltiude

lspec: Produce spectrograms of whole recordings split into multiple rows

specreator: Create spectrograms of manualoc selections

snrspecs: Create spectrograms to visualize margins over which noise will be measured by sig2noise

sig2noise: Measure signal-to-noise ratio across multiple files

trackfreqs: Create spectrograms to visualize frequency measurements

specan: Measure acoustic parameters on selected acoustic signals

xcorr: Pairwise cross-correlation of multiple signals

xcorr.graph: Pairwise cross-correlation of multiple signals

dfts: Extract the dominant frequency values as a time series

coor.graph: Creat graphs of coordinated singing

coor.test: Assess statistical significance of singing coordination

Details
