Usage

sound_to_formant_batch(
  sounds,
  time_step = 0.005,
  max_formants = 5,
  max_frequency = 5500,
  window_length = 0.025,
  pre_emphasis_from = 50,
  return_r6 = TRUE
)

Arguments

sounds: List of Sound objects (R6) or external pointers
time_step: Numeric. Time step in seconds (default: 0.005)
max_formants: Numeric. Maximum number of formants (default: 5)
max_frequency: Numeric. Maximum frequency in Hz (default: 5500)
window_length: Numeric. Window length in seconds (default: 0.025)
pre_emphasis_from: Numeric. Pre-emphasis from frequency (default: 50)
return_r6: Logical. Return R6 Formant objects (TRUE) or raw xptrs (FALSE)

Value

List of Formant objects (R6 or xptr depending on return_r6)

Examples

sounds <- list(
  Sound$create_tone(frequency = 150, duration = 0.5),
  Sound$create_tone(frequency = 200, duration = 0.5)
)
formants <- sound_to_formant_batch(sounds)
