41The biquad filter output and frequency characteristics are represented as follows.
42      </p><p><pre>y(n) = n0 * x(n) + n1 * x(n-1) + n2 * x(n-2) + d1 * y(n-1) + d2 * y(n-2)</pre></p><p><pre>

44H(z) = ----------------------------
451  - d1(Z^-1) - d2(Z^-2)</pre></p><p>
46The coefficients can all be specified as Q14-format 16-bit integers, comprising a 2-bit integer portion and a 14-bit fractional portion. Sounds may be clipped if the filter gain is higher than 1.
