Description

This function removes the offset of a time wave.

Usage

rmoffset(wave, f, plot = FALSE, ...)

Arguments

wave

a vector, a matrix (first column), an object of class ts, Sample (left channel), or Wave (left channel).

f

sampling frequency of wave (in Hz). Does not need to be specified if wave is an object of class ts, Sample, or Wave

plot

logical, if TRUE returns an oscillographic plot of the wave after removing the offset (by default FALSE).

...

other oscillo graphical parameters.

Value

• If plot is FALSE, rmoffset returns a one-column matrix describing the new wave with the same sampling frequency as the original wave.

Examples

data(tico)
# artifically generates an offset
tico2<-tico+0.1
# see the wave with an offset
oscillo(tico2,f=22050)
# remove the offset
rmoffset(tico2,f=22050,plot=TRUE)
