Create DTW from two Spectrogram objects

Usage

spectrograms_to_dtw(
  spectrogram1,
  spectrogram2,
  match_start = TRUE,
  match_end = TRUE,
  slope = 1,
  metric = 2
)

Arguments

spectrogram1: First spectrogram (candidate)
spectrogram2: Second spectrogram (reference)
match_start: Force path to start at (1,1)
match_end: Force path to end at (nx,ny)
slope: Slope constraint (1-4)
metric: Distance metric power (default: 2 = Euclidean)

Value

A DTW object

Examples

s1 <- Sound$create_tone(frequency = 200, duration = 0.3, sampling_rate =
 16000)
s2 <- Sound$create_tone(frequency = 220, duration = 0.3, sampling_rate =
 16000)
dtw <- spectrograms_to_dtw(s1$to_spectrogram(), s2$to_spectrogram())
