Common Variables

A = 10^(boost/40)

ω0 = 2*pi*f0/Fs

alpha = sin(ω0)/(2*Q) (type: Peaking)

= sin(ω0)/2 * sqrt((A + 1/A)*(1/S - 1) + 2) (type: Shelving)

gainLinear = 10^(gain/20)

so the value :

boost

pi

f0

Fs

ω0

gain

the value of these parameters is what ?

thank you !

boost= The amount of boost applied to the filter. You set this in the filter control GUI with a slider.pi=π= 3.14159265...f0= The center frequency of the filter, which you set in the GUI.Fs= The audio sampling rate of the system.ω0= Center frequency referenced to the sample rate of the system... you don't need to know what this is... just calculate it using the provided equations.gain= Linear gain of the filter (i.e. gain that is applied equally to all frequencies).
