System and method for audio system configuration
First Claim
1. An audio system comprising at least one crossover filter, the crossover filter selected based on a method comprising:
- generating acoustic signals from at least one loudspeaker placed at potential loudspeaker locations;
recording transfer functions for the generated acoustic signals at a plurality of listening positions;
modifying the transfer functions based on potential crossover filters in order to generate predicted transfer functions;
statistically analyzing across at least one frequency of the predicted transfer functions for the plurality of listening positions; and
selecting a crossover filter for the audio system based on the statistical analysis.

Abstract
A system is provided for configuring an audio system for a given space. The system may statistically analyze potential configurations of the audio system to configure the audio system. The potential configurations may include positions of the loudspeakers, numbers of loudspeakers, types of loudspeakers, listening positions, correction factors, filters, or any combination thereof. The statistical analysis may indicate at least one metric of the potential configuration including indicating consistency of predicted transfer functions, flatness of the predicted transfer functions, differences in overall sound pressure level from seat to seat for the predicted transfer functions, efficiency of the predicted transfer functions, or the output of predicted transfer functions. The system also provides a methodology for selecting loudspeaker locations, the number of loudspeakers, the types of loudspeakers, correction factors, listening positions, crossover filters or a combination of these schemes in an audio system that has a single listening position or multiple listening positions.
