Techniques for providing audio for synchronized playback by multiple devices

摘要

An audio system communicates with an aggregate device that includes multiple audio devices. When providing audio data for playback, the system compensates for presentation latency differences between the various audio devices. In addition, the system adjusts for device clock drift by selecting a master device and resampling the audio data provided to the other devices based on the difference between the device clock of the master device and the device clocks of the other devices.
