Choice of inverse filter design parameters in virtual acoustic imaging systems
Choice of inverse filter design parameters in virtual acoustic imaging systems
Reproducing a pair of binaural signals over loudspeakers requires crosstalk cancellation filters that create sound at the two ears corresponding to a transparent delivery of the intended source material. Such filtering is effectively inverting the actual response of the loudspeakers to the two ears. The authors explore the consequences of inversion, especially when the response lasts longer than that of a strictly anechoic environment. The choice of inverse design parameters proves more difficult than expected. The authors conclude that the required knowledge of the actual environment is equivalent to making in situ measurements.

Abstract
Reproducing a pair of binaural signals over loudspeakers requires crosstalk cancellation filters that create sound at the two ears corresponding to a transparent delivery of the intended source material. Such filtering is effectively inverting the actual response of the loudspeakers to the two ears. The authors explore the consequences of inversion, especially when the response lasts longer than that of a strictly anechoic environment. The choice of inverse design parameters proves more difficult than expected. The authors conclude that the required knowledge of the actual environment is equivalent to making in situ measurements.
