1. A computer-implemented method of generating audio signals for an array of loudspeakers positioned in a listening environment, the method comprising:
receiving at least one input audio signal;
at a first time, determining at least one of:
a number of users in the listening environment, or
a respective position of each of one or more users in the listening environment;
at a second time, based on the at least one of the number of users or the respective position of each of the one or more users in the listening environment, selecting a sound reproduction mode from a set of predetermined sound reproduction modes of the array of loudspeakers, wherein the set of predetermined sound reproduction modes comprises one or more user-position-independent modes and one or more user-position-dependent modes;
generating a respective output audio signal for each of the loudspeakers in the array of loudspeakers based on at least a portion of the at least one input audio signal, wherein the output audio signals are generated according to the selected sound reproduction mode;
at a third time, determining at least one of the number of users in the listening environment and the respective position of each of the one or more users in the listening environment;
at a fourth time, repeating the selecting based on the at least one of the number of users or the respective position of each of the one or more users in the listening environment at the third time; and
repeating the generating based on the selecting at the fourth time, wherein:
the determined number of users at the first time is a first determined number of users and the determined number of users at the third time is a second determined number of users, the second determined number of users being higher than the first determined number of users,
the selected sound reproduction mode at the second time is one of the one or more user-position-dependent modes, and
the selected sound reproduction mode at the fourth time is one of the one or more user-position-independent modes.
