38<h2>Description of SetMonoFilterCoefficients(const MonoFilterCoefficients &)</h2>
39    <div class="section"><p>
40The monopole filter output can be represented as follows.
41</p><p><pre>y(n) = n0 * x(n) - d0 * y(n-1)</pre></p><p>
42The coefficients can all be specified as Q15-format 16-bit integers, comprising a 1-bit integer portion and a 15-bit fractional portion. Sounds may be clipped if the filter gain is higher than 1.
43      </p></div>
44<h2>Description of <CODE>SetMonoFilterCoefficients(u16)</CODE></h2>
45    <div class="section"><p>
46The cut-off frequency, <CODE>cutoff</CODE>, is designed from the monopole filter and configured to <CODE>Voice</CODE>. <CODE>cutoff</CODE> must fall within the range 0 &lt;= <CODE>cutoff</CODE> &lt;= 16,000.
