Detailed Description

An IIR filter that can perform low, band and high-pass filtering on an audio signal, with 12 dB of attenuation / octave, using a TPT structure, designed for fast modulation (see Vadim Zavalishin's documentation about TPT structures for more information).

Its behaviour is based on the analog state variable filter circuit.

Note : the bandpass here is not the one in the RBJ CookBook, its gain can be higher than 0 dB. For the classic 0 dB bandpass, we need to multiply the result with R2
