Generate multiple spectrograms using SoX — sox.spectrograms • TrillR

This function uses SoX to generate a multiple spectrograms of desired length from wav files.

sox.spectrograms(
  data,
  out.path = file.path(getwd(), "Spectrograms"),
  size = list(x = 1200, y = 500),
  duration = list(start = 0, end = 180),
  doParallel = FALSE
)

Arguments

data	Selection data.frame containing a file.path column with paths to wavs to generate spectrograms.
out.path	A string of the folder path to save the spectrogram file. Defaults to create a Spectrogram folder in your working directory.
size	A list for the x and y size in px of the spectrogram. Default is x = 1200 and y = 500 which is faster than the sox.spectrogram default.
duration	A list for the start and end time of the spectrogram in seconds. Default is start = 0 and end = 180 for a 3 min clip.
doParallel	Binary TRUE or FALSE whether to run process in parallel to save time. Will work better on some machines vs others.

Examples

sox.spectrogram(data,out.path = file.path(getwd(),"Spectrograms"), duration = list(start = 0, end = 180))
