rmoffset {seewave} | R Documentation |
This function removes the offset of a time wave.
rmoffset(wave, f, plot = FALSE, ...)
wave |
data describing a time wave
or a Sample object generated loading a wav file
with loadSample (package sound). |
f |
sampling frequency of wave (in Hz).
Does not need to be specified if wave is a Sample object. |
plot |
logical, if TRUE returns an oscillographic plot of the wave
after removing the offset (by default FALSE ). |
... |
other oscillo graphical parameters. |
If plot
is FALSE
, rmoffset
returns a one-column matrix
describing the new wave with the same sampling frequency as the original wave.
