dPhase: Phase derivatives

In soundgen: Sound Synthesis and Acoustic Analysis

Phase derivatives

Description

Internal soundgen function called by pitchShift().

Usage

dPhase(
  phase,
  magn,
  step_s,
  freqs,
  alpha,
  propagation = c("time", "adaptive")[1],
  tol = 10^(-6),
  nr = nrow(phase),
  nc = ncol(phase)
)

Arguments

phase, magn	phase and magnitude of a spectrogram
step_s	step in s
freqs	a vector of central frequencies per bin
alpha	stretch factor
propagation	the method for propagating phase: "time" = horizontal propagation (default), "adaptive" = an experimental implementation of "vocoder done right" (Prusa & Holighaus 2017)
tol	tolerance of "vocoder done right" algorithm
nr, nc	dimensions of input spectrogram
