Utility function to save <literal>.wav</literal> sound file.
<literal>wavwrite(y,wavfile)</literal> writes a sound file specified by
the string wavfile. The data should be arranged with one channel per
column. Amplitude values outside the range [-1,+1] are ignored.
</para>
<para>
<literal>wavwrite(y,Fs,wavfile)</literal> specifies in
<literal>Fs</literal> the sample rate of the data in Hertz.
