harmHeight_dif: Height of harmonics: difference method

In soundgen: Sound Synthesis and Acoustic Analysis

Height of harmonics: difference method

Description

Internal soundgen function

Usage

harmHeight_dif(
  frame_dB,
  pitch,
  bin,
  freqs,
  harmThres = 3,
  harmTol = 0.25,
  harmPerSel = 5,
  plot = FALSE
)

Arguments

pitch	the final pitch estimate for the current frame
bin	spectrogram bin width, Hz
freqs	frequency per bin of spectrogram
harmThres	minimum height of spectral peak, dB
harmTol	maximum tolerated deviation of peak frequency from multiples of f0, proportion of f0
harmPerSel	the number of harmonics per sliding selection
plot	if TRUE, produces a plot of spectral peaks

Details

Estimates how far harmonics reach in the spectrum by analyzing the typical distances between spectral peaks in different frequency regions.
