Loudspeaker response data can be decomposed into minimum and excess phase components. Subjectively less significant elements can then be filtered and a new family of response curves computed. Applications to both cumulative-decay spectra (CDS) and energy-time curves (ETC) are discussed, where noncausal attributes are corrected. Some observations using digital processing for transfer function modification are also presented together with the implications on CDS and ETC.
