dio: Compute f0 using the Harvest algorithm

In humlab-speech/superassp: A speech signal processing using various framworks using a wrassp-like interface

Compute f0 using the Harvest algorithm

Description

The DIO algorithm \insertCitemorise2010rapidsuperassp was developed for the WORLD vocoder \insertCiteMORISE.2016.10.1587/transinf.2015edp7457superassp and aims provide a fast estimate of the f0 contour.

Usage

dio(
  listOfFiles,
  beginTime = 0,
  endTime = 0,
  windowShift = 5,
  minF = 70,
  maxF = 200,
  voiced_voiceless_threshold = 0.01,
  explicitExt = "wd0",
  outputDirectory = NULL,
  toFile = TRUE
)

Arguments

listOfFiles	A vector of file paths to wav files.
beginTime	The start time of the section of the sound file that should be processed.
endTime	The end time of the section of the sound file that should be processed.
windowShift	The measurement interval (frame duration), in seconds.
minF	Candidate f0 frequencies below this frequency will not be considered.
maxF	Candidates above this frequency will be ignored.
explicitExt	the file extension that should be used.
outputDirectory	set an explicit directory for where the signal file will be written. If not defined, the file will be written to the same directory as the sound file.
toFile	write the output to a file? The file will be written in outputDirectory, if defined, or in the same directory as the soundfile.
voiced.voiceless.threshold	Threshold for voiced/unvoiced decision. Can be any value >= 0, but 0.02 to 0.2 is a reasonable range. Lower values will cause more frames to be considered unvoiced (in the extreme case of threshold=0, almost all frames will be unvoiced).

Value

An SSFF track object containing two tracks (f0 and corr) that are either returned (toFile == FALSE) or stored on disk.
