Time-varying generalizations of all-pass filters [PDF]
IEEE Signal Processing Letters, 2005 In many audio applications, digital all-pass filters are of central importance; a key property of such filters is energy (l/sub 2/ norm) preservation. In audio effect and sound synthesis algorithms, it is desirable to have filters that behave as all-passes with time-varying characteristics, but direct generalizations of time-invariant designs can lose ...
