Create a dynamic sonagram as video clip using dynaSpec

Description

Implements dynamic sonagrams as .mp4 files as explained in much detail here (here)[https://marce10.github.io/dynaSpec/] Only works if (FFMPEG)[https://ffmpeg.org/download.html] is installed (see (wikihow tutorial)[https://www.wikihow.com/Install-FFmpeg-on-Windows] to get help)

Usage

sona.vid(
  wave = NULL,
  res = 120,
  wl = 1024,
  ymin = 0,
  ymax = 9,
  loop = 1,
  scalecexlab = 0.5,
  scalefontlab = 0.5,
  cexlab = 0.5,
  cexaxis = 0.5,
  t.range = 10,
  tlab = "",
  flab = "kHz",
  colbg = c("black", "white"),
  fix.time = F,
  out = "default"
)

Arguments

wave	path to a .mp3 or .wav audio file.
res	res
wl	A numeric vector of length 1 specifying the window length of the spectrogram, default is NULL. If supplied, 'hop.size' is ignored.
ymin	min frequency
ymax	max frequency
loop	Logical argument to control if the video is formatted to be played in a loop (i.e. if ends at the start of the clip).
scalecexlab	scalecexlab
scalefontlab	scalefontlab
cexlab	cexlab
cexaxis	cexaxis
t.range	x-axis width in seconds
tlab	name of time (x) axis
flab	name of frequency (y) axis
colbg	Character string to control the background color. Default is 'white'.
fix.time	Logical argument to control if the time axis moves along with the spectrogram or remains fixed. Default is TRUE (fixed).
out	output file name
