Description

Plot waveform and spectrogram

Usage

praat_plot(
  file,
  wav,
  tg = NULL,
  start = 0,
  end = NULL,
  width = 5,
  format = "png",
  f0 = FALSE,
  f0_min = 0,
  f0_max = 500,
  spec_max = 5000
)

Arguments

file	Output file path as a string.
wav	Wav file path as a string.
tg	TextGrid file path as a string. If NULL (the default), a TextGrid is plotted if a TextGrid file with the same name as the wav file is found. No TextGrid is plotted otherwise.

width	Width of the plot in inches.
format	Output file format (png by default, or pdf).
f0	Whether to plot f0 (FALSE by default).
f0_min	If f0 = TRUE, minimum f0 value (0 by default).
f0_max	If f0 = TRUE, maximum f0 value (500 by default).
spec_max	Maximum frequency for the spectrogram (5000 by default).

Value

Nothing. It is used for its side effects.

Examples

## Not run: 
wav <- system.file("extdata", "vowels.wav", package = "speakr")
