Zap silence periods of a time wave
This function simply deletes the silence periods of a time wave.
zapsilw(wave, f, channel = 1, threshold = 5, plot = TRUE, output = "matrix", ...)
wave |
an R object. |
f |
sampling frequency of |
channel |
channel of the R object, by default left channel (1). |
threshold |
amplitude threshold (in %) between silence and signal. |
plot |
logical, if |
output |
character string, the class of the object to return, either
|
... |
other |
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.
