51The monopole filter output can be represented as follows.
52      </p><p><pre>y(n) = n0 * x(n) - d0 * y(n-1)</pre></p><p>
53The 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.
