zapsilw {seewave} | R Documentation |
This function simply deletes the silence periods of a time wave.
zapsilw(wave, f, threshold = 5, plot = TRUE, output = "matrix", ...)
wave |
an R object. |
f |
sampling frequency of wave (in Hz). Does not need to be specified if embedded in wave . |
threshold |
amplitude threshold (in %) between silence and signal. |
plot |
logical, if TRUE plots the orginal and the new oscillograms
(by default TRUE ). |
output |
character string, the class of the object to return, either
"matrix" , "Wave" , "Sample" , "audioSample" or "ts" . |
... |
other oscillo graphical parameters. |
If plot
is FALSE
, a new wave is returned. The class
of the returned object is set with the argument output
.
Use the argument threshold
to set the level of silence. See
the examples
.
