#X text 15 62 reson~ implements the following filter equation: y[n]
= gain * (x[n] - r * x[n-2]) + c1 * y[n-1] + c2 * y[n-2] \, where r
\, c1 \, and c2 are parameters calculated from the input center frequency
and Q. Q is the filter bandwidth divided by center frequency. Inputs
can be floats or signals. The specification is similar to the nres
unit generator in cmusic.;
