101. And sending first audio data with a first code rate to the client.
In this way, the client can play the first audio data.
102. Receiving an audio switching instruction sent by the client, wherein the audio switching instruction is used for indicating switching from a switching point to second audio data with a second code rate; wherein the first audio data and the second audio data are generated according to the same data source.
103. And sending second audio data after the switching point to the client according to the audio switching indication.
In this way, the client can then continue to play the second audio data after the switch point.
It should be noted that the execution subjects of 101 to 103 may be audio processing engines, and may be located in a server on a network side to perform online audio data processing, which is not limited in this embodiment.
It should be understood that the client may be an application installed on the terminal, or may also be a web page of a browser, as long as the audio playing function can be implemented to provide an objective existence form of the audio service, which is not limited in this embodiment.
In this way, after a client receives first audio data with a first code rate, by receiving an audio switching instruction sent by the client, the audio switching instruction is used to instruct to switch from a switching point to second audio data with a second code rate, where the first audio data and the second audio data are generated according to the same data source, so that the second audio data after the switching point can be sent to the client according to the audio switching instruction, and a problem that the client cannot request to continue playing the same content from a current time but audio data with another code rate in a process of playing audio data with a certain code rate in the prior art can be avoided, thereby realizing switching of the code rates of the audio data in a playing process of the audio data.
Optionally, in a possible implementation manner of this embodiment, the audio switching indication may include, but is not limited to, switching point information and target audio data identification information; wherein,
the switching point information is used for identifying the switching point;
the target audio data identification information is used to identify the second audio data.
Wherein the switching point may include a switching time and/or switching content. For example, the switching time may be 2 minutes and 50 seconds, waiting for the playing time of the audio data; alternatively, for another example, the switching content may be xxxxx, or the like, lyrics of the audio data.
Optionally, in a possible implementation manner of this embodiment, after 101, the client may further determine whether there is the second audio data in the cached data according to the audio switching indication.
If the client determines that the second audio data does not exist in the cached data, or if the client determines that the second audio data exists in the cached data and the switching point does not exist second audio data after the corresponding initial position in the cached second audio data, the client may determine to send the audio switching indication.
If the client determines that the second audio data exists in the cached data and the second audio data exists after the corresponding initial position in the cached second audio data at the switching point, the client can directly read the second audio data after the cached initial position.

Then, the audio processing engine may further send the second audio data after the start position to the client, so that the client plays the second audio data after the start position.
Specifically, the audio processing engine may specifically perform a slicing process on the second audio data after the start position to obtain at least two partitions. Specifically, the second audio data after the start position may be subjected to the slicing process according to a preset block size, for example, 512 k/block. Then, the audio processing engine may send each chunk after the start position to the client in turn, so that the client plays each chunk after the start position. In this way, the data volume contained in each block is far smaller than the data volume of the second audio data after the initial position, so that the second audio data after the initial position can be sent to the client in real time, the client can start playing the second audio data after the initial position as soon as possible, and the real-time performance of code rate switching of the audio data is improved.
In this embodiment, after a client receives first audio data with a first code rate, by receiving an audio switching instruction sent by the client, the audio switching instruction is used to instruct to switch from a switching point to second audio data with a second code rate, where the first audio data and the second audio data are generated according to the same data source, so that the second audio data after the switching point can be sent to the client according to the audio switching instruction, and a problem that the client cannot request to continue playing audio data with the same content but with another code rate from a current time in a process of playing audio data with a certain code rate in the prior art can be avoided, thereby implementing switching of code rates of audio data in a playing process of audio data.
