Create DTW from two Pitch objects

Create DTW from two Pitch objects

Usage

pitches_to_dtw(
  pitch1,
  pitch2,
  vuv_costs = 24,
  time_weight = 10,
  match_start = TRUE,
  match_end = TRUE,
  slope = 1
)

Arguments

pitch1

First pitch contour (candidate)

pitch2

Second pitch contour (reference)

vuv_costs

Cost for voiced-unvoiced mismatches (default: 24)

time_weight

Weight for temporal distance (default: 10)

match_start

Force path to start at (1,1)

match_end

Force path to end at (nx,ny)

slope

Slope constraint (1-4)

Value

A DTW object

Examples

sound1 <- Sound$create_tone(frequency = 220, duration = 0.5)
sound2 <- Sound$create_tone(frequency = 440, duration = 0.5)
pitch1 <- sound1$to_pitch()
pitch2 <- sound2$to_pitch()
dtw <- pitches_to_dtw(pitch1, pitch2)
