System for configuring audio system
First Claim
1. A method for selecting a number of speakers for an audio system, the method comprising:
- generating acoustic signals from at least one loudspeaker placed at potential loudspeaker locations;
recording transfer functions at a plurality of listening positions for the generated acoustic signals;
determining at least one potential number of speakers;
modifying the transfer functions based on the potential number of speakers 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 at least one loudspeaker location 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, 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, or a combination of these schemes in an audio system that has a single listening position or multiple listening positions.
