摘要
An audio system provides modified audio signals for acoustic output sources (speakers) disposed around a listening area. A sound allocation processor receives an audio source signal. A plurality of audio modifying elements, each of which may comprise one or more custom filters, operate separately on the audio source signal and provide a custom output signal for each acoustic output source. The audio modifying elements may modify a gain and/or a phase characteristic of the audio source signal independently for each acoustic output source in order to create a substantially uniform sound level or desired sound field pattern over the listening area or within defined zones within the listening area. A global equalization adjustment may also be applied. Search algorithms may be used to arrive at appropriate parameters for the audio modifying elements.
