mutew

Replace time wave data by 0 values

Description

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.

Usage

mutew(wave, f, channel = 1, from = NULL, to = NULL, choose = FALSE, plot = TRUE,
output = "matrix", ...)

Arguments

`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).
`from`	start of the silence section (in s).
`to`	end of the silence section (in s).
`choose`	logical, if `TRUE` start (=`from`) and end (=`to`) points can be graphically chosen with a cursor on the oscillogram.
`plot`	logical, if `TRUE` returns an oscillographic plot of `wave` with the new silence section (by default `TRUE`).
`output`	character string, the class of the object to return, either `"matrix"`, `"Wave"`, `"Sample"`, `"audioSample"` or `"ts"`.
`...`	other `oscillo` graphical parameters.

Details

By default, from and from are NULL, this results in completely muting wave.

Value

If plot is FALSE, a new wave is returned. The class of the returned object is set with the argument output.
