Create Pitch from Sound using Subharmonic Summation (SHS) Directly (returns XPtr)

Usage

to_pitch_shs_direct(
  sound,
  time_step = 0.01,
  pitch_floor = 50,
  max_frequency = 1250,
  pitch_ceiling = 500,
  max_subharmonics = 15L,
  max_candidates = 15L,
  compression_factor = 0.84,
  n_points_per_octave = 48L
)

Arguments

sound: Sound object or external pointer
time_step: Time step in seconds (default 0.01)
pitch_floor: Minimum pitch (Hz, default 50)
max_frequency: Maximum frequency for analysis (Hz, default 1250)
pitch_ceiling: Maximum pitch (Hz, default 500)
max_subharmonics: Number of subharmonics to sum (default 15)
max_candidates: Maximum number of pitch candidates per frame (default 15)
compression_factor: Compression factor for subharmonic weighting (default 0.84)
n_points_per_octave: Number of frequency points per octave (default 48)

Value

External pointer to Pitch (NOT R6 object)

Examples

sound <- Sound$create_tone(frequency = 200, duration = 0.5)
pitch_ptr <- to_pitch_shs_direct(sound)
f0 <- get_pitch_value_direct(pitch_ptr, 0.25, "hertz", TRUE)
