Create PointProcess from Sound Directly (returns XPtr)

Usage

to_point_process_direct(
  sound,
  pitch_floor = 75,
  pitch_ceiling = 600,
  time_step = 0,
  max_period_factor = 1.3,
  max_amplitude_factor = 1.6
)

Arguments

sound: Sound object or external pointer
pitch_floor: Numeric. Minimum pitch in Hz (default: 75)
pitch_ceiling: Numeric. Maximum pitch in Hz (default: 600)
time_step: Numeric. Time step in seconds (0 = auto)
max_period_factor: Numeric. Max period factor (default: 1.3)
max_amplitude_factor: Numeric. Max amplitude factor (default: 1.6)

Value

External pointer to PointProcess

Examples

sound <- Sound$create_tone(frequency = 200, duration = 0.5)
# Extract glottal pulses
pp_ptr <- to_point_process_direct(sound, pitch_floor = 75, pitch_ceiling =
 300)
pp <- PointProcess(.xptr = pp_ptr)
pp$get_number_of_points()
#> [1] 96
