The Minimum Phase lter is another highly regarded audio lter that offers even lower ripple in

the pass and stop bands. Unlike the Linear Phase lter, group delay is not constant so some time-

coherence is lost; however, phase shift is low and the particular benet with this lter is that the

impulse response exhibits no pre-ringing.
