dot-flatEnv: Flat envelope per sound

In soundgen: Sound Synthesis and Acoustic Analysis

Flat envelope per sound

Description

Internal soundgen function

Usage

.flatEnv(
  audio,
  compression = 1,
  method = c("hil", "rms", "peak")[1],
  windowLength = 50,
  windowLength_points = NULL,
  killDC = FALSE,
  dynamicRange = 40,
  plot = FALSE,
  col = "blue",
  width = 900,
  height = 500,
  units = "px",
  res = NA,
  ...
)

Arguments

audio	a list returned by readAudio
compression	the amount of compression to apply: 0 = none, 1 = maximum
method	hil = Hilbert envelope, rms = root mean square amplitude, peak = peak amplitude per window
windowLength	the length of smoothing window, ms
windowLength_points	the length of smoothing window, points. If specified, overrides windowLength
killDC	if TRUE, dynamically removes DC offset or similar deviations of average waveform from zero (see examples)
dynamicRange	parts of sound quieter than -dynamicRange dB will not be amplified
plot	if TRUE, plots the original sound, the smoothed envelope, and the compressed sound
col	the color of amplitude contours
width, height, units, res	graphical parameters for saving plots passed to png
...	other graphical parameters passed to points() that control the appearance of amplitude contours, eg lwd, lty, etc.
