In the “EQ Target” page, the magnitude response of the target curve (blue line), of the FIR filter
(green line) and of the IRxFIR (yellow curve) are overlaid. Curves in the plot can be hidden through
the corresponding check-boxes at the top right of the screen.
To change the target curve, up to ten parametric IIR filter is available. The IIR filter prototype is
just a drawing aid, since the target magnitude is included in the compensating FIR filter generation.
The parametric filter can be set by the controls at the bottom of the screen or by dragging the
cursors in the plotting area.
The EQ target can be bypassed (or enabled) by clicking the “EQ Bypass” checkbox at the top center
of the screen. Clicking the “Flat EQ Target” button, the gain of each parametric filter is set to 0dB
to flatten the target curve.
Enabling the target curve smoothing allows to reduce unwanted ripples in the magnitude response
when low frequency filters are set with high gain and/or high Q.
The target curve can be also saved in a file to be easily recalled from a different Wizard project.
To apply the target curve to the compensating FIR filter the “EQ Target” window should be closed
and the “OK” button must be clicked in the confirmation pop-up.
