Result = READ_WAV ( Filename [, Rate] )
In the case of a single channel stream, the returned variable is a BYTE or INT (depending on the number of bits per sample) one-dimensional array. In the case of a file with multiple channels, a similar two-dimensional array is returned, with the leading dimension being the channel number.
A scalar string containing the full pathname of the .WAV file to read.
