This function removes background noise by smoothing
rmnoise(wave, f, channel = 1, output = "matrix", ...)A new wave is returned. The class
of the returned object is set with the argument output.
an R object.
sampling frequency of wave (in Hz). Does not need to
be specified if embedded in wave.
channel of the R object, by default left channel (1).
character string, the class of the object to return, either
"matrix", "Wave", "Sample", "audioSample" or "ts".

This function is based on smooth.spline. You can
use the arguments of the later to modify the smoothing.
