soundgen (version 2.7.2)

.osc: Oscillogram per sound

Description

Internal soundgen function called by osc.

Usage

.osc(
  audio,
  dynamicRange = 80,
  dB = FALSE,
  returnWave = FALSE,
  plot = TRUE,
  main = NULL,
  xlab = NULL,
  ylab = NULL,
  ylim = NULL,
  bty = "n",
  midline = TRUE,
  maxPoints = 10000,
  width = 900,
  height = 500,
  units = "px",
  res = NA,
  ...
)

Arguments

dynamicRange

dynamic range, dB. All values more than one dynamicRange under maximum are treated as zero

dB

if TRUE, plots on a dB instead of linear scale

returnWave

if TRUE, returns a log-transformed waveform as a numeric vector

plot

if TRUE, plots the oscillogram

main

plot title

xlab, ylab

axis labels

ylim

override default amplitude scale for non-centered sounds

bty

box type (see `?par`)

midline

if TRUE, draws a line at 0 dB

maxPoints

the maximum number of points to plot (speeds up the plotting of long audio files, but beware of antialiasing)

width, height, units, res
