Abstract

A method for configuring a digital audio filter (8) includes: providing a decaying impulse response in the time domain, representing at least part of the transfer characteristics of the digital audio filter (8); determining the poles and zeros of the decaying impulse response in the z-domain; selecting at least one subset of the poles and zeros of the decaying impulse response; and, for each of the at least one subset of the poles and zeros: determining a respective subset impulse response (70) in the time domain, windowing the respective subset impulse response in the time domain, and configuring the digital audio filter (8) in accordance with the windowed respective subset impulse response (72; 74; 76; 78; 80; 82; 84).
