System for selecting correction factors for an audio system

摘要

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.

主权项

1. An audio system comprising at least one correction factor, the correction factor 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; determining a plurality of potential correction factors; modifying the transfer functions based on the potential correction factors so that predicted transfer functions are generated for each of at least two of the plurality of listening positions for each of the plurality of potential correction factors, the predicted transfer functions representing simulations for the potential correction factors; accessing a criterion by which to statistically analyze the predicted transfer functions; statistically analyzing using the criterion across at least one frequency of the predicted transfer functions for the at least two of the plurality of listening positions; and selecting a correction factor to improve for the criterion at the at least two of the plurality of listening positions based on the statistical analysis, where the statistical analysis indicates flatness for the predicted transfer functions.
