the value of the sigma DSP EQ Coefficients parameters
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 !
Moved to the SigmaDSP Processors forum.
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).
