Abstract
A method comprising: generating at least one audio signal to be output by at least one speaker for a multi-speaker system; receiving at least two output signals, the at least two output signals provided by at least two microphones and based on the at least one acoustic wave output by the at least one speaker in response to the at least one audio signal; determining a directional component associated with the at least two output signals; and comparing the directional component with an expected location of the at least one speaker.
