sampleLength(s)
sampleLength(s) <- value
setSampleLength(s,value)

`s`	a Sample object, or a string giving the name of a wav file.
`value`	an integer giving the sample length (number of columns in the waveform matrix).

The replacement form can be used to reset the sample length (here, filenames are not accepted).

If a Sample object is shortened, extra values are discarded. When a Sample object is lengthened, it is padded out to its new length with zeros (silence).

For sampleLength, the number of columns in the waveform matrix of the sample.

For setSampleLength, a Sample object with the new length.
