Abstract
A system capable of directing audio output to a portion of a shared acoustic environment. For example, the system may divide the environment into two or more sound zones and may generate audio output directed to one or more sound zones. The system may distinguish between target sound zones and quiet sound zones and may determine a set of global filter coefficients with which to direct the audio output. The system may generate a first set of filter coefficients that increase audio volume in the target sound zones and a second set of filter coefficients that increase a ratio of audio volume between the target sound zones and the quiet sound zones. The system may generate the set of global filter coefficients using a combination of the first set and the second set. The system may also direct audio from multiple audio sources in different directions.
