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
NULLin 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.
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)
#> [1] TRUE TRUE
# here are two .wav files in a folder
list.files(tdir)
#> [1] "bslib-1b356e302cd67848882ff8e9c32a1ced"
#> [2] "downlit"
#> [3] "file6371a5650f4"
#> [4] "post.wav"
#> [5] "test.wav"
# [1] "post.wav" "test.wav" ...
# Concatenate all files from the folder into concatenated.wav and create
# corresponding TextGrid
