Abstract

The invention relates to an audio synchronization method and system of bluetooth equipment. The method includes: selecting a to-be-played target audio data packet when receiving a synchronization request of bluetooth slave computer equipment; obtaining a first time value required by the period from the playing of current audio data to the playing of data of the target audio data packet, and addingthe first time value to the target audio data packet; and sending the target audio data packet with the added first time value to the bluetooth slave computer equipment, wherein bluetooth host equipment plays audios corresponding to the target audio data packet after passing a time corresponding to the first time value, and the bluetooth slave computer equipment can adjust the playing moment of the target audio data packet according to the first time value. According to the method and system, the audios corresponding to the target audio data packet can be played at the same moment, the audiodelay inequality of the bluetooth host equipment and the bluetooth slave computer equipment can be reduced, the usage effects of the bluetooth host equipment and the bluetooth slave computer equipmentafter abnormal communication are improved, and audio synchronization of the bluetooth equipment is realized.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to a Bluetooth device audio synchronization method and system. Background technique [0002] With the development of audio technology, the application of multi-channel analog stereo technology is becoming more and more extensive. Applying multi-channel analog stereo technology to the advanced audio of Bluetooth devices can truly reproduce the sound of the original sound field and bring better listening effects to users. [0003] The advanced audio of the Bluetooth device is to connect the different channels of the host device and the slave device through Bluetooth, so that different channels can play the same audio file. During the use of the Bluetooth device, there will be packet loss in the slave device, such as the audio signal being interfered, the audio data sent and received is abnormal, etc., resulting in the number of audio packets of the master and slave devices b...
