Parallel Formant Extraction — extract_formant

Extract formants from multiple files in parallel.

Usage

extract_formant_parallel(
  files,
  n_cores = NULL,
  time_step = 0.005,
  max_formants = 5,
  max_frequency = 5500
)

Arguments

files: Character vector of file paths
n_cores: Integer. Number of cores (default: auto)
time_step: Numeric. Time step in seconds (default: 0.005)
max_formants: Numeric. Max number of formants (default: 5)
max_frequency: Numeric. Max frequency in Hz (default: 5500)

Value

List of Formant objects

Examples

audio_dir <- tempfile("audio_")
dir.create(audio_dir)
tone <- Sound$create_tone(frequency = 220, duration = 0.3, sampling_rate =
 16000)
tone$save(file.path(audio_dir, "tone1.wav"))
files <- list.files(audio_dir, pattern = "\\.wav$", full.names = TRUE)

# n_cores = 1 keeps this a single-process example (CRAN-safe)
formants <- extract_formant_parallel(files, n_cores = 1)
#> Using single core (set n_cores > 1 for parallel processing)
