R Documentation

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 `wave` (in Hz). Does not need to be specified if embedded in `wave`.
`channel`	channel of the R object, by default left channel (1).
`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.

data(orni)
zapsilw(orni,f=22050,colwave="red")
# setting the threshold value
zapsilw(orni,f=22050,threshold=1)
