Abstract:
1. An automated audio tuning system executable on a computer, comprising: a setup file configured to store audio system specific configuration settings for an audio system, where the audio system includes a plurality of amplified channels and a plurality of phase modifying filters to be tuned, and where information included in the setup file describes the audio system being tuned; a measurement interface configured to receive and process an audio response from a plurality of loudspeakers collectively driven by the plurality of amplified audio channels in a listening space, the loudspeakers operable together in the audio system in the listening space to generate the audio response measured by the measurement interface; a response matrix configured to store the measured audio response received from the plurality of collectively driven loudspeakers; and a bass optimization engine executable with the computer to generate filter design parameters for each of the phase modifying filters, where the phase modifying filters are associated with a selected group of amplified channels included in the plurality of amplified channels, the selected group of amplified channels identified in the setup file as driving a respective subset of the plurality of loudspeakers, the phase modifying filters configured to provide a phase adjustment for each of the amplified channels included in the selected group of amplified channels based on the measured audio response and the audio system specific configuration settings to optimize summation of audible audio responses of the selected group of amplified channels at a listening position within the listening space.
