mutew: Replace time wave data by 0 values

In seewave: Sound Analysis and Synthesis

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.
