The technical scheme of the invention is further explained by combining the drawings and the embodiment.
The embodiment provides a method for switching an audio decoder, which is applied to an audio playing device, and as shown in fig. 1, the method includes:
101. the audio playing device establishes a connection with an audio source.
The audio playing device may be, but is not limited to, a speaker, a sound box, an earphone, or other electronic devices capable of playing audio. The audio source can be, but is not limited to, a cloud streaming server, an audio storage device, a local electronic device capable of connecting to the cloud streaming server, or other devices capable of providing an audio output signal to the audio player

The acquisition time interval is set to allow the audio decoder to switch with real-time reference to the on-line quality parameter. In the actual acquisition process, the acquisition time interval can be set to be proper according to the requirements of designers, and even can be set to be zero so as to acquire the online quality parameters in real time.
For example, in one embodiment, the acquisition time interval is set to 10 s. I.e. data acquisition is performed every 10 s. For the setting of the acquisition time interval, the user may select according to different actual needs, which is not limited herein.
103. Whether the on-line quality parameter reaches a decoder switching condition is judged.

104. And if the online quality parameter does not reach the switching condition of the decoder, the audio playing equipment maintains the current playing setting.
More specifically, when the on-line quality parameter does not meet the decoder switching condition, the audio playing device continues to use the currently used audio decoder, and if the audio playing device is in a state of just being started, the preset audio decoder is used. In some embodiments, if the on-line quality parameter does not meet the decoder switching condition, the on-line quality parameter is continuously collected according to the collection time interval, and whether the decoder switching condition is met is determined.
105. And if the online quality parameter reaches the decoder switching condition and the audio playing equipment is in an output blank state, switching the audio playing equipment to an audio decoder corresponding to the online quality parameter.
More specifically, when the on-line quality parameter reaches the decoder switching condition, the audio playing device selects the corresponding audio decoder according to the on-line quality parameter, and when the audio playing device is in the output blank state, the audio playing device is switched to the audio decoder corresponding to the on-line quality parameter.
In some embodiments, the audio playback device may further set the newly set audio decoder as the default audio decoder at the next time the audio playback device is started.
The output blank state is a state in which the audio playing device does not play the audio signal, and if viewed from the user, the output blank state is a state in which the user cannot listen to the audio signal through the audio playing device. The output blank state can be, but not limited to, a time interval of audio pause playing, a time interval of audio track switching, or a time interval of any audio interruption playing, and the output blank state is not limited to a state triggered by a user.
In some embodiments, when the audio playing device is in the output blank state, the corresponding audio decoder can be selected according to the on-line quality parameter, and the sequence of the two steps does not deviate from the core idea of the scheme, so that a designer can set the audio decoder according to the requirement of the designer.
In the method for switching an audio decoder, the following embodiments may be further included:
in one embodiment, the decoder switching condition includes at least one switching upper limit value and/or one switching lower limit value, and when the on-line quality parameter reaches the switching upper limit value or the switching lower limit value, the on-line quality parameter is judged to reach the decoder switching condition. The switching upper limit value can be a multi-segment upper limit value, and the switching lower limit value can be a multi-segment lower limit value, so that more audio decoders can be provided correspondingly, and various audio decoders which are possibly suitable can be provided.
In an embodiment, referring to fig. 2, an implementation flow of switching the audio playback device to an audio decoder corresponding to the on-line quality parameter when the on-line quality parameter is the received signal strength value is shown.
The online quality parameter is the received signal strength value, when the received signal strength value reaches the switching upper limit value, the audio decoder which judges that the current online quality of the audio playing equipment and the audio source can bear higher requirements is judged, and then
Therefore, the audio decoder corresponding to the on-line quality parameter is the audio decoder with higher on-line quality requirement.
When the received signal strength value reaches the switching lower limit value, it is determined that the current on-line quality of the audio playing device and the audio source cannot bear the currently used audio decoder, and a better listening experience is provided by selecting and switching to the audio decoder more suitable for the current on-line quality.
In another embodiment, referring to fig. 3, an implementation flow of switching the audio playback device to an audio decoder corresponding to the on-line quality parameter when the on-line quality parameter is the bit error rate or the packet error rate is shown.
The on-line quality parameter is bit error rate or packet error rate;
when the bit error rate or the packet error rate reaches the switching upper limit, it is determined that the current on-line quality of the audio playback device and the audio source cannot bear the currently used audio decoder, and a switching to the audio decoder more suitable for the current on-line quality is required, so as to provide a better listening experience.
When the bit error rate or the packet error rate reaches the switching lower limit, it is determined that the current on-line quality of the audio playback device and the audio source can bear a higher audio decoder, and a selection is made to switch to an audio decoder more suitable for the current on-line quality, so as to provide a better listening experience.
In addition, referring to fig. 4, another implementation flow for determining whether the connection quality parameter meets the decoder switching condition according to the embodiment of the present application is shown.

403. If the usable data amount is 0, the on-line quality parameter is determined to meet the preset switching condition of the decoder.
Compared with the switching condition setting corresponding to other on-line quality parameters, the switching value needs to be set while the current value needs to be acquired, and the on-line quality parameters can be determined to meet the switching condition of the decoder only by acquiring the available data quantity and judging the available data quantity to be 0, so that the judgment process is simple, and the system efficiency is improved.
Wherein, the usable data size of the data buffer is used as a decoder for judging whether the online quality meets the preset requirement
The switching condition of (1). Specifically, when the usable data amount is 0, it indicates that the usable data amount of the data buffer is empty. When the available data volume is empty, the system is indicated to have a music blank, and the music blank indicates that the current communication quality of the system is poor and the system is not matched with the current corresponding audio decoder.
In other embodiments, another implementation flow for switching the audio playback device to an audio decoder corresponding to the on-line quality parameter is shown in fig. 5, and includes:
501. when the online quality parameters meet the switching conditions of the decoders, audio switching information is generated and comprises option components corresponding to each audio decoder;
502. displaying audio switching information and acquiring a selection instruction for the option component by a user;
503. and when the selection instruction is acquired, switching the current audio decoder to the audio decoder corresponding to the selected option component.
Through the option component, the user can carry out proper adjustment according to actual use requirements, and the music experience of the user is improved.
The option component may be a box, a table, or a text, and is not specifically limited herein.
The generated audio switching information is obtained by analyzing the current online quality parameter and the current corresponding audio decoder through the processor. In some embodiments, the following steps are performed:
when the online quality parameters meet the switching conditions of the decoders, analyzing the current online quality parameters and the current corresponding audio decoders to generate audio switching information, wherein the audio switching information is optimal pairing information according to the current online quality parameters and the corresponding audio decoders.
The audio switching information is available for the user to view, and then, a selection instruction for the option component by the user is acquired. After the selection instruction is obtained, the current audio decoder is switched to the one corresponding to the selected option component
An audio decoder.
In the method for switching audio decoders, the embodiment in which the on-line quality parameter is the packet error rate is exemplified. It is understood that the online quality parameter of the present embodiment can be changed into other applicable parameter types according to the above description.
Wherein the packet error rate is used to determine the packet transmission rate. The calculation of the packet error rate may be analyzed by a processor, i.e. the processor may be adapted to perform the following steps:
first, a plurality of first packets are received in a wireless mode within a first preset time period, and a packet error rate is calculated according to the received first packets. To ensure the validity of the calculated packet error rate, the total number of packets is accumulated to a certain amount before the packet error rate is calculated.
Specifically, for the implementation process of calculating the packet error rate, as shown in fig. 6, 601, obtaining a preset packet number value and receiving a plurality of first packets within a first preset time period; 602. judging whether the number of the received first packets is greater than a packet number preset value or not; 603. if the number of the first packets is larger than the preset value of the number of the packets, calculating the packet error rate in a first preset time period according to the first packets; 604. if the number of the first packets is smaller than the preset number of packets, a plurality of second packets are continuously received within a second preset time, and packet error rates of the first preset time and the second preset time are calculated according to the first packets and the second packets.
And judging the packet error rate and the decoder switching condition, and switching the current audio decoder to a proper audio decoder according to the judgment result, so that the output tone quality of the audio playing equipment is matched with the online quality, and the influence of the environment on the output tone quality is reduced.
The higher the packet error rate, the poorer the quality of the wireless communication, and the current audio decoder needs to be switched to the audio decoder with the lower on-line quality requirement to meet the requirement of the external environment. In contrast, the lower the packet error rate, which indicates better quality of wireless communication, the current audio decoder needs to be switched to the audio decoder with higher on-line quality requirement.
In summary, the method for switching the audio decoders provides selecting the audio decoder suitable for the on-line quality to provide the user with better listening experience, and in addition, in order to avoid the interruption of listening caused by switching the audio decoder, the method for switching the audio decoders switches the audio decoder in the output blank state, so that the user can be prevented from feeling the interruption of listening caused by switching the audio decoder.
