dot-fade: Fade per sound

In soundgen: Sound Synthesis and Acoustic Analysis

Fade per sound

Description

Internal soundgen function

Usage

.fade(
  audio,
  fadeIn = 1000,
  fadeOut = 1000,
  fadeIn_points = NULL,
  fadeOut_points = NULL,
  samplingRate = NULL,
  shape = c("lin", "exp", "log", "cos", "logistic", "gaussian")[1],
  steepness = 1,
  plot = FALSE,
  width = 900,
  height = 500,
  units = "px",
  res = NA,
  ...
)

Arguments

audio	a list returned by readAudio
fadeIn, fadeOut	length of segments for fading in and out, ms (0 = no fade)
fadeIn_points, fadeOut_points	length of segments for fading in and out, points (if specified, override fadeIn/fadeOut)
samplingRate	sampling rate of x (only needed if x is a numeric vector)
shape	controls the type of fade function: 'lin' = linear, 'exp' = exponential, 'log' = logarithmic, 'cos' = cosine, 'logistic' = logistic S-curve
steepness	scaling factor regulating the steepness of fading curves (except for shapes 'lin' and 'cos'): 0 = linear, >1 = steeper than default
plot	if TRUE, produces an oscillogram of the waveform after fading
width, height, units, res	graphical parameters for saving plots passed to png
...	other graphical parameters
