Abstract:
A method, apparatus and device for synchronously playing audio are provided. The method includes: acquiring status information of a Bluetooth controller in the first audio playing device and Bluetooth time from the Bluetooth controller, and determining native Bluetooth time of the first audio playing device based on the status information and the Bluetooth time acquired from the Bluetooth controller; estimating, based on the native Bluetooth time of the first audio playing device and offset time of the native Bluetooth time of the first audio playing device relative to native Bluetooth time of a second audio playing device or native Bluetooth time of an audio providing device, absolute time of the second audio playing device or absolute time of the audio providing device; and playing an audio signal provided by the audio providing device synchronously with the second audio playing device based on the estimated absolute time.
