The Minimum Phase filter is another highly regarded audio filter that offers even lower ripple in the
pass and stop bands. Unlike the Linear Phase filter, group delay is not constant so some time-
coherence is lost; however, phase shift is low and the particular benefit with this filter is that the
impulse response exhibits no pre-ringing.
