Usage

extractAudioFeatures(
  wav.dir = getwd(),
  wav.fnames = NULL,
  windowSize = 25,
  windowShift = 12.5,
  windowType = "HAMMING",
  derivatives = 2,
  verbose = 1,
  recursive = FALSE
)

Arguments

wav.dir

Directory of wav files for featurization

wav.fnames

If wav.dir = NULL, a list of wav files for featurization

windowSize

Size of window in milliseconds

windowShift

Amoung to shift window in milliseconds

windowType

Window type

derivatives

Include no (0), first (1), or first and second (2) derivatives of features

verbose

Verbose printing

recursive

Recursively traverse directory for wav files

Value

An object of class preppedAudio, which consists of a list of 'data', 'files', and 'control'. 'data' is a list with elements corresponding to audio features for each of the input wav files, where each element is the audio features for the respective wav file. 'files' contains metadata about each wav file for which audio features were extracted. 'control' records arguments passed to extractAudioFeatures().

                        full.names = TRUE
                        )
audio <- extractAudioFeatures(wav.fnames = wav.fnames,
