Extract Pitch from Multiple Sounds in Single C++ Call — sound_to_pitch_batch • pladdrr

Processes multiple Sound objects and extracts Pitch at the C++ level, avoiding O(n) R→C boundary crossings from calling `$to_pitch()` in a loop.

Usage

sound_to_pitch_batch(
  sounds,
  time_step = 0,
  pitch_floor = 75,
  pitch_ceiling = 600,
  return_r6 = TRUE
)

Arguments

sounds: List of Sound objects (R6) or external pointers
time_step: Numeric. Time step (0 = automatic)
pitch_floor: Numeric. Pitch floor in Hz (default: 75)
pitch_ceiling: Numeric. Pitch ceiling in Hz (default: 600)
return_r6: Logical. Return R6 Pitch objects (TRUE) or raw xptrs (FALSE)

Value

List of Pitch 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)
)
pitches <- sound_to_pitch_batch(sounds)
