findSyllables: Find "syllables" (discrete acoustic events) in animal sounds

In vrios/songspellR: Automates syllable detection and classification in bioacoustic analyses

Description

Find "syllables" (discrete acoustic events) in animal sounds

Usage

findSyllables(
  files,
  low = 1000,
  high = 22000,
  plotSyllables = FALSE,
  samplingRate = NULL,
  shortestPause = 25,
  shortestSyl = 10,
  plot = FALSE,
  sylThres = 0.5,
  windowLength = 20,
  overlap = 80
)

Arguments

files	A vector of wave files
low	lower frequency for filter
high	lower frequency for filter
plotSyllables	logical, should the spectrogram with the syllables be plotted?
samplingRate	Sampling rate
shortestPause	Smallest separation between syllables
shortestSyl	Shortest event that cam be considered a syllables
plot	should plot syllables according to soundgen?
sylThres	percentage of mean amplitude envelope for audio event. Syllables are only detected when above this threshold
windowLength	window size for audio events
overlap	overlap between windows

Value

Dataframe with following collumns: "sound.files" : original file from wich syllables were extracted, "selec" : syllable id, unique inside the sound.file, but not between files, "start" : syllable start, "end" : syllable end

Examples

## Not run: 
songs = findSyllables(plotSyllables  = F,dir(here::here("inst/extdata"),
 full.names = TRUE,include.dirs = T), samplingRate = 44100)
 
## End(Not run)
