split_wavs
splits sound files in shorter segments
split_wavs(path = NULL, sgmt.dur = 10, sgmts = NULL, files = NULL,
parallel = 1, pb = TRUE)
Directory path where sound files are found.
If NULL
(default) then the current working directory is used.
Numeric. Duration (in s) of segments in which sound files would be split. Sound files shorter than 'sgmt.dur' won't be split. Ignored if 'sgmts' is supplied.
Numeric. Number of segments in which to split each sound file. If supplied 'sgmt.dur' is ignored.
Character vector indicating the subset of files that will be analyzed.
Numeric. Controls whether parallel computing is applied. It specifies the number of cores to be used. Default is 1 (i.e. no parallel computing).
Logical argument to control progress bar. Default is TRUE
.
Wave files for each segment in the working directory (named as 'sound.file.name-#.wav') and a data frame in the R environment containing the name of the original sound files (org.sound.files), the name of the cuts (sound.files) and the start and end of cuts in the original files.
This function aims to reduce the size of sound files in order to simplify some processes that are limited by sound file size (big files can be manipulated, e.g. auto_detec
).
