Digital analysis of loudspeaker performance

There is growing awareness of the usefulness of digital signal processing in audio. One area of application is the use of digital techniques in loudspeaker performance analysis. This paper describes an interactive computer system for loudspeaker measurement. In particular, the use of the cepstrum is discussed for the characterization of loudspeaker and room responses and for the determination of group delay and minimum-phase group delay curves for loudspeakers.
