In phonfieldwork: Linguistic Phonetic Fieldwork Tools

Description Usage Arguments Value Author(s) Examples

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.

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

`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.
