Label Slices of Wave Files — label

Plug the labels from a set of annotations (made by annotator_app) in a dataset of slices (made by slice_wavs).

label_slices(slices_dir, annotations, pattern = NULL)

Arguments

slices_dir	atomic character. Path to dir where the slices are (see `slice_wavs`).
pattern	atomic character. A regex pattern to select files from 'slices_dir'. Useful to filter out just specifc types of labels (see examples).
annotations_dir	atomic character or a tibble. If character, path to dir where the annotations are. If tibble, a tibble created by `tidy_annotations`.

Value

tibble of slices with label column.

Examples


slices_dir <-  system.file("wav_sample_slices_1000ms", package = "mestrado")
annotations_dir <-  system.file("annotations", package = "mestrado")
slices_1000ms_labels <- label_slices(
  slices_dir, 
  annotations_dir, 
  pattern = "Glaucidium|Megascops-atricapilla"
)
