Functions in warbleR (1.1.0)

Check .wav files

Import Raven selections

Interactive view of spectrograms

Import Syrinx selections

Selections of simulated interactive singing events. The simulated events use the mean and standard deviation of real lekking Phaethornis longirostris (Long-billed Hermit hummingbird) songs and intervals between songs. Three events are simulated: overlapping signals (ovlp), alternating signals (altern) and non-synchronized signals (no.sync). .

Pairwise plots of spectrogram cross-correlation scores

Acoustic recording #2 of Phaethornis longirostris (Long-billed Hermit).

Measure signal-to-noise ratio

Data frame of manualoc() selections.

Spectrogram cross-correlation

Coordinated singing graphs

Measure acoustic parameters in batches of sound files

Extract the dominant frequency values as a time series

selection.files

Selections files from Raven and Syrinx.

warbleR: A package to streamline bioacoustic analysis

Automatically detect vocalizations in sound files

Spectrograms with background noise margins

Create long spectrograms of whole sound files

Acoustic recording #3 of Phaethornis longirostris (Long-billed Hermit).

Acoustic recording #4 of Phaethornis longirostris (Long-billed Hermit).

Acoustic recording #1 of Phaethornis longirostris (Long-billed Hermit).

Spectrograms with frequency measurements

Access Xeno-Canto recordings and metadata

Convert .mp3 files to .wav

Maps of Xeno-Canto recordings by species

Randomization test for singing coordination

Simulated coordinated singing events.
