Audio Filter Biquad

Generic biquad filter.

See biquad-calculator-v2 for coefficients calculation.

Settings

bypass

Bypasses the module.

in

Audio input.

out

Audio output.

gain

Output gain of the filter.

On this module, the gain isn't smoothed so quick variations can produce audio glitches. To modify the gain in real time, use a volume module.

A

Biquad coefficients.

B

Biquad coefficients,assuming B0=1.

the generic formula for the biquad filter is:
Out(n) = A0*in(n)+A1*in(n-1)+A2*in(n-2)+B1*out(n-1)+B2*out(n-2)

caption

plot bins

Array which contains the values of the plotted points.

bins size

Number of points used to draw the equalization curve.

Increase size for a smoother curve.

calc plot bins if invisible

If enabled, the module calculates the filter plot bin's even if it's invisible.

Can be used to chain bitmap layers and hide the original source.
