| revw {seewave} | R Documentation |
Reverse the wave along the time axis.
revw(wave, f, plot = FALSE, Sample = 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 reversed wave (by default FALSE). |
Sample |
if TRUE and plot is FALSE
returns an object of class Sample |
... |
other oscillo graphical parameters. |
If plot is TRUE returns an oscillogram of the reversed
wave.
If plot is FALSE, a new wave is returned as a one-column matrix
or as a Sample object if Sample is TRUE.
