Problems solved by technology
[0009]1. Send synchronous coded data to each second speaker. This synchronous coded data includes data of 12 channels. The amount of data is relatively large. The TV and the second speaker The network between the speakers causes a transmission burden, affects real-time transmission, and easily causes the playback of the second speaker to be stuck and out of sync with the TV playback
[0010]2. Each second speaker needs to decode synchronous encoded data. When the decoding complexity is high, the processing burden of the second speaker will be increased, affecting the second The processing power of the speaker may easily cause the playback of the second speaker to freeze and be out of sync with the TV playback
[0011]3. In order to save traffic, if a high-compression coding algorithm is used for synchronous coding, the sound quality will be damaged and the playback effect will be affected.

The invention provides a method and a device for playing audio data and a medium. The method comprises the following steps: acquiring multi-channel audio data; extracting first sound channel audio data and at least one second sound channel audio data from the multi-sound channel audio data, encoding the first sound channel audio data, and adding a first timestamp to the encoded first sound channel audio data to obtain first audio synchronous encoding data; encoding the second sound channel audio data, and adding a second timestamp to the encoded second sound channel audio data to obtain second audio synchronous encoding data, wherein the second timestamp is used for synchronizing the second sound box with the first sound box; sending the first audio synchronous coding data to the first sound box; and sending the second audio synchronous coding data to the second sound box. According to the invention, the processing efficiency of the second sound box can be improved, the synchronization rate of audio playing is improved, and the load of a wireless communication network is reduced.
Description
technical field [0001] The present disclosure relates to the technical field of data processing, in particular to a method, device and readable storage medium for playing audio data. Background technique [0002] In one implementation, the same TV is simultaneously connected to two smart speakers through short-range wireless communication technology (such as Bluetooth or WIFI). The first speaker is built into the television. The above two smart speakers include a second speaker 1 and a second speaker 2 . The data of different channels in the audio data can be played simultaneously through the first built-in speaker in the TV and the two smart speakers, so as to realize surround sound, which can improve the auditory effect compared with the case of only using the first built-in speaker in the TV. [0003] like figure 1 As shown in , the processor in the TV receives audio compression data from the server through the network, and the audio compression data corresponds to 12 ...
