    Abstract: A method for adjusting audio being outputted through a beam forming loudspeaker array. Program audio is rendered to drive the loudspeaker array to produce sound beams having i) a main content pattern that is aimed at a listener, superimposed with ii) several diffuse content patterns that are aimed away from the listener. In response to receiving an alert message that refers to alert audio, the portion of the program audio in the main pattern is moved into the diffuse patterns, and the alert audio is rendered to drive the loudspeaker array so that the portion of the program audio in the main pattern is replaced with the alert audio. Other embodiments are also described and claimed.
