Abstract:
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.
