Abstract:
A method includes determining a network counter value indicative of a network clock time of a system at a first time instant and a second time instant occurring later in time than the first time instant. The method further includes determining an audio counter value indicative of an audio clock time of the system at a third time instant occurring the first and second time instants and a fourth time instant occurring later in time than the second time instant. The method further includes determining an offset based upon the determined network counter values and the audio counter values. The method further includes adjusting the audio clock time based upon the determined offset to synchronize operation of at least one audio component operating according to the audio clock with at least one audio component operating according to the network clock. An associated system is also disclosed.
