mutew {seewave} | R Documentation |
This functions replaces a time wave or a section of a time wave by 0 values. For a time wave describing a sound, this corresponds in muting the sound or a section of it.
mutew(wave, f, from = FALSE, to = FALSE, plot = TRUE, Sample = FALSE,...)
wave |
data describing the 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. |
from |
start of the silence section (in s). |
to |
end of the silence section (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. |
By default, from
and from
are FALSE
,
this results in completely muting wave
.
If plot
is FALSE
, a new wave is returned as a one-column matrix
or as a Sample
object if Sample
is TRUE
.
