concatenate_soundfiles: Concatenate sounds

In phonfieldwork: Linguistic Phonetic Fieldwork Tools

Concatenate sounds

Description

Creates a merged sound file from old sound files in a folder. If the annotation argument is not equal to NULL, it creates an annotation file (Praat .TextGrid, ELAN .eaf or EXMARaLDA .exb) with original sound names annotation.

Usage

concatenate_soundfiles(
  path,
  result_file_name = "concatenated",
  annotation = "textgrid",
  separate_duration = 0
)

Arguments

path	path to the directory with soundfiles.
result_file_name	name of the result and annotation files.
annotation	character. There are several variants: "textgrid" for Praat TextGrid, "eaf" for ELAN's .eaf file, or "exb" for EXMARaLDA's .exb file. It is also possible to use NULL in order to prevent the creation of the annotation file.
separate_duration	double. It is possible to add some silence between concatenated sounds. This variable denotes duration of this soundless separator in seconds.

Value

no output

Examples

# create two files in a temprary folder "test_folder"
s1 <- system.file("extdata", "test.wav", package = "phonfieldwork")
s2 <- system.file("extdata", "post.wav", package = "phonfieldwork")
tdir <- tempdir()
file.copy(c(s1, s2), tdir)

# here are two .wav files in a folder
list.files(tdir)
# [1] "post.wav" "test.wav" ...

# Concatenate all files from the folder into concatenated.wav and create
# corresponding TextGrid
concatenate_soundfiles(path = tdir, result_file_name = "concatenated")

list.files(tdir)
# [1] "concatenated.TextGrid" "concatenated.wav" "post.wav" "test.wav" ...
