istft_mod: Modified istft

In soundgen: Sound Synthesis and Acoustic Analysis

Modified istft

Description

Internal soundgen function. Similar to seewave:::istft(), but adapted to work with time-variable step sizes in the context of dynamic pitch shifting. Only call it for dynamic istft because the original seewave function should be a bit faster for static.

Usage

istft_mod(
  stft,
  f,
  wl,
  ovlp = 75,
  wn = "hanning",
  mult_short = 1,
  mult_long = 1
)

Arguments

stft, f, wl, ovlp, wn	see seewave:::istft()
mult_short	stretch factor of length ncol(stft) - 1
mult_long	stretch factor of length ncol(stft)
