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 |
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" . |
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
.
