EQUALS

IR Length IR Length determines the number of data points captured. At a given sample rate, more data = longer duration. Low frequencies require longer time to develop and therefore measure, a higher resolution IR creates a more accurate representation of the overall sound of a speaker cab.

Garbage in, garbage out.
