Reducing the latency below 2.5ms is even possible, with a lower compensation accuracy.
The picture below shows the magnitude, group delay and phase plots for a latency value equals to
1.5ms: the frequency response starts to be significantly different from the ideal one, especially for
the magnitude response (see the yellow curves)
As a general rule, it is suggested to try different values for the latency parameter and choose the
lower one that still gives satisfying equalization results for the particular application, basing on
plotted curves and listening tests.

Target Curve
To set up a target magnitude curve, click the “EQ Target” button at the top left of the “Calculate
FIR” page, and the “EQ Target” window is shown.
