Extract Parts and Analyze Pitch in Single C++ Call — sound_extract_and

Combines interval extraction and pitch analysis in a single C++ call, avoiding intermediate R6 object creation, as an alternative to extracting each part and calling `$to_pitch()` on it in a loop.

Usage

sound_extract_and_pitch(
  sound,
  from_times,
  to_times,
  time_step = 0,
  pitch_floor = 75,
  pitch_ceiling = 600,
  return_r6 = TRUE
)

Arguments

sound: Sound object (R6) or external pointer
from_times: Numeric vector of start times
to_times: Numeric vector of end times
time_step: Numeric. Pitch 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

sound <- Sound$create_tone(frequency = 150, duration = 2.0)
from_times <- c(0.2, 1.0)
to_times <- c(0.6, 1.4)
pitches <- sound_extract_and_pitch(sound, from_times, to_times)
