Abstract

A filter structure is proposed which has a significantly lower signal delay than common frequency-domain filtering by means of an analysis-synthesis filter-bank (AS FB). The recently published filter-bank equalizer (FBE) is a filter(-bank) with a lower signal delay compared to the corresponding AS FB. In this contribution, the signal delay of the FBE is further reduced by approximating the time-domain filter of the FBE by a filter of lower degree. The proposed low delay filter (LDF) achieves a higher amount of noise reduction than an AS FB or FBE with the same signal delay.
