R Documentation

Flat spectrum per sound

Description

Internal soundgen function, see flatSpectrum.

Usage

.flatSpectrum(
  audio,
  freqWindow = NULL,
  samplingRate = NULL,
  dynamicRange = 80,
  windowLength = 50,
  step = NULL,
  overlap = 90,
  wn = "gaussian",
  zp = 0,
  play = FALSE,
  saveAudio = NULL
)

Arguments

`audio`	a list returned by `readAudio`
`freqWindow`	the width of smoothing window, Hz. Defaults to median pitch estimated by `analyze`
`samplingRate`	sampling rate of `x` (only needed if `x` is a numeric vector)
`dynamicRange`	dynamic range, dB. All values more than one dynamicRange under maximum are treated as zero
`windowLength`	length of FFT window, ms
`step`	you can override `overlap` by specifying FFT step, ms (NB: because digital audio is sampled at discrete time intervals of 1/samplingRate, the actual step and thus the time stamps of STFT frames may be slightly different, eg 24.98866 instead of 25.0 ms)
`overlap`	overlap between successive FFT frames, %
`wn`	window type accepted by `ftwindow`, currently gaussian, hanning, hamming, bartlett, blackman, flattop, rectangle
`zp`	window length after zero padding, points
`play`	if TRUE, plays the processed audio
`saveAudio`	full (!) path to folder for saving the processed audio; NULL = don't save, ” = same as input folder (NB: overwrites the originals!)
