| addsilw {seewave} | R Documentation |
Add or insert a silence section to a time wave.
addsilw(wave, f, at = "end", choose = FALSE, d = NULL, plot = FALSE, Sample = FALSE,...)
wave |
a vector, a matrix (first column),
an object of class ts, Sample (left channel),
or Wave (left channel). |
f |
sampling frequency of wave (in Hz).
Does not need to be specified if wave is an object of class ts,
Sample, or Wave. |
at |
position where to add the silence section (in s).
Can be also specified as "start", "middle" or "end". |
choose |
logical, if TRUE the point where silence will
be added into wave2 (=at) can be graphically chosen with a cursor. |
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). |
Sample |
if TRUE and plot is FALSE
returns an object of class Sample |
... |
other oscillo graphical parameters. |
If plot is FALSE, a new wave is returned as a one-column matrix
or as a Sample object if Sample is TRUE.
