| 摘要 | 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. | ||

| 主权项 | 1. An apparatus comprising: a signal generator configured to generate at least one audio signal to be output by at least one speaker for a multi-speaker system comprising a plurality of speakers; at least two microphones distinct from the at least one speaker of the multi-speaker system and disposed at a listening position that is spaced apart from the at least one speaker of the multi-speaker system, wherein the at least two microphones are configured to provide at least two output signals based on the acoustic output of the at least one speaker in response to the at least one audio signal; an audio signal analyser configured to determine a directional component associated with the at least two output signals; and a calibration processor configured to compare the directional component with an expected location of the at least one speaker so as to adjust audio playback of the at least one speaker. | ||
