Add or insert a silence section to a time wave.
addsilw(wave, f, at = "middle", d = FALSE, plot = FALSE, ...)
wave |
data describing a time wave
or a Sample object generated loading a wav file
with loadSample (package Sound). |
f |
sampling frequency of wave (in Hz).
Does not need to be specified if wave is a Sample object. |
at |
position where to add the silence section (in s). Can be also specified as "start", "middle" or "end". |
d |
duration of the silence section to add (in s). |
plot |
logical, if TRUE returns an oscillographic plot
of wave with the new silence section (by default TRUE). |
... |
other oscillo graphical parameters. |
New wave is returned as one-column matrix if plot is FALSE.
