A parametric EQ that uses a fixed point, direct form 2 transposed, implementation of a Butterworth filter. The following parameters can be adjusted: Gain (dB), Bandwidth Gain (dB), Centre frequency (Hz), Bandwidth (Hz), Order, Type (Peaking, Bandstop, Bandpass, Low Shelf, High Shelf, Low Pass or High Pass).
