Abstract
(EN) Provided are an audio synchronization playback method, apparatus, electronic device (600), and storage medium, relating to the field of data processing. The method is applied to a first audio playback device, the method comprising: obtaining status information of a Bluetooth controller in a first audio playback device, and determining the local Bluetooth time of the first audio playback device according to the status information (S201); on the basis of the local Bluetooth time of the first audio playback device, and offset data of the local Bluetooth time of the first audio playback device relative to the local Bluetooth time of a second audio playback device or the local Bluetooth time of an audio-providing device, estimating the absolute time of the second audio playback device or the audio-providing device (S202); on the basis of the estimated absolute time, in synchronization with the second audio playback device, playing an audio signal provided by the audio-providing device (S203). The invention can effectively improve the accuracy of audio playback synchronization.
(FR) Sont divulgués un procédé de lecture à synchronisation audio, un appareil, un dispositif électronique (600) et un support d'enregistrement, appartenant au domaine du traitement des données. Le procédé est appliqué à un premier dispositif de lecture audio, le procédé comprenant : l'obtention d'informations d'état d'un dispositif de commande Bluetooth dans un premier dispositif de lecture audio, et la détermination du temps de Bluetooth local du premier dispositif de lecture audio en fonction des informations d'état (S201) ; sur la base du temps de Bluetooth local du premier dispositif de lecture audio, et des données de décalage du temps de Bluetooth local du premier dispositif de lecture audio par rapport au temps de Bluetooth local d'un second dispositif de lecture audio ou du temps de Bluetooth local d'un dispositif de fourniture audio, l'estimation du temps absolu du second dispositif de lecture audio ou du dispositif de fourniture audio (S202) ; sur la base du temps absolu estimé, en synchronisation avec le second dispositif de lecture audio, la lecture d'un signal audio fourni par le dispositif de fourniture audio (S203). L'invention peut améliorer de manière efficace la précision de synchronisation de lecture audio.
(ZH) 一种音频同步播放方法、装置、电子设备(600)及存储介质,涉及数据处理领域。方法应用于第一音频播放设备,方法包括:获取第一音频播放设备中的蓝牙控制器的状态信息,并根据状态信息确定第一音频播放设备的本地蓝牙时间(S201);基于第一音频播放设备的本地蓝牙时间,以及第一音频播放设备的本地蓝牙时间相对于第二音频播放设备的本地蓝牙时间或者音频提供设备的本地蓝牙时间的偏移数据,预估第二音频播放设备或者音频提供设备的绝对时间(S202);基于预估的绝对时间,与第二音频播放设备同步播放音频提供设备提供的音频信号(S203)。能够有效提高音频播放同步的精度。
