PEAK GAIN FILTER
----------------

Two-poles peak gain filter (resonator).

Allows gain adjustment in dB of a very narrow frequency band (peak), either negative (notching, down to -oo) or positive (resonating, theorically unlimited).


NOTE: static updates are not supported because it would make not much sense with this kind of filter; any static voltage on input is converted to silence.

NOTE: the higher the gain, the longer the filter will resonate, this is physiological. With a very high gain (>50 dB or so), the filter can even resonate for a very long time or indefinitely !

NOTE: for stereo signals, please use the stereo version of this filter, which is much more efficient than using two distinct mono versions.
