Usage

better.spectro(
  wave,
  main = "",
  wl = 512,
  ovl = wl/2,
  xlim = NULL,
  ylim = NULL,
  mar = rep(3, 4),
  cex.main = 1,
  cex.axis = 0.75,
  cex.lab = 0.5
)

Arguments

wave

wave object, e.g., from 'load.wave' or 'readWave'.

main

character, title for the spectrogram. Default is no title.

wl

numeric, window length in samples. Default is '512'.

ovl

numeric, overlap in samples. Default is 'wl/2'.

xlim

numeric vector of length 2, limits for the x-axis. Default is no limits.

ylim

numeric vector of length 2, limits for the y-axis. Default is no limits.

mar

numeric vector of length 4, the margins of the plot for the 'impagep' function. Default is 'rep(3, 4)'.

cex.main

numeric the relative size of the title

cex.axis

numeric the relative size of the axis labels.

cex.lab

numeric the relative size of the axis titles

Value

Plots the spectrogram to current window.
