Fig. 1 is a flowchart of an automatic volume adjustment method according to an embodiment of the present disclosure. As shown in fig. 1, the automatic volume adjustment method includes the following steps S11 to S13.
In step S11, the history volume used by the user in the history audio playback event is acquired.
In the present disclosure, the audio may be music played by an application such as QQ music, dog search music, or may also be video played by an application such as tremble, love art, or the like. An audio play event refers to a play event such as music, video, etc.
In the present disclosure, a user may be identified by a user identification, wherein the user identification may be a user account or other identifier capable of uniquely identifying the user, and the like. For example, if a user registers for a buffeting account, then the buffeting account may be used to identify which user is currently using buffeting. Therefore, no matter the user plays the audio on the same terminal or different terminals, the historical volume used by the user in the historical audio playing event can be obtained, and further, the automatic adjustment of the playing volume can be realized for the user when the user triggers the next audio playing event on different terminals. Here, the terminal may be a handheld terminal such as a mobile phone and a tablet computer, a terminal such as a smart television, a smart audio playing terminal such as a mini-speaker, and the like.
In the disclosure, the terminal may record the historical volume used by the user in the historical audio playing event and send the historical volume to the server, so that the server can acquire the historical volume used by the same user in the historical audio playing event on various terminals. For example, during audio playback, the terminal may record the volume of playing back an audio stream each time the audio stream is played back, or the terminal may record the current audio playback volume at preset intervals, and so on. Here, the information stream may be music, video, etc. selected by the user himself, or may be music, video, advertisement, etc. automatically pushed to the user by the application playing audio. In addition, the terminal may transmit the volume to the server every time it records one volume, or the terminal may periodically transmit the recorded history volumes to the server, or the terminal may transmit all the history volumes recorded during the audio play to the server together at the end of the audio play. In fact, the present disclosure does not limit the manner in which the terminal records the volume and the manner in which the volume is transmitted to the server.
In the present disclosure, the historical audio playing event and the next audio playing event are both audio playing events in the earphone mode, or the historical audio playing event and the next audio playing event are both audio playing events in the play-out mode. For example, the history volume in the headphone mode may be acquired in a headphone volume acquisition table, and the history volume in the play-out mode may be acquired in a play-out volume acquisition table. In this way, the historical volume used by the user in the historical audio playback event can be separately obtained for the headphone mode and the play-out mode. Further, in the subsequent step S12, the historical volume in the headphone mode and the historical volume in the play-out mode can be clustered, and further, in the subsequent step S13, when the user triggers the next audio playing event, the volume can be automatically adjusted based on the clustering result of the historical volume in the play-out mode if the user is currently in the play-out mode, and the volume can be automatically adjusted based on the clustering result of the historical volume in the headphone mode if the user is currently in the headphone mode.
In the present disclosure, the historical audio playing event and the next audio playing event are both audio playing events under the android system, or the historical audio playing event and the next audio playing event are both audio playing events under the ios system. For example, the historical volume under the android system may be acquired in an android volume acquisition table, and the historical volume under the ios system may be acquired in an ios volume acquisition table. Due to the fact that the volume values of the volume keys of the android system and the ios system are different, through the technical scheme, the historical volume used by the user in the historical audio playing event can be separately acquired for the android system and the ios system. Furthermore, in subsequent step S12, the historical volume under the android system and the historical volume under the ios system can be clustered, and further, when the user triggers the next audio playing event in subsequent step S13, if the current event is the android system, the volume can be automatically adjusted based on the clustering result of the historical volume under the android system, and if the current event is the ios system, the volume can be automatically adjusted based on the clustering result of the historical volume under the ios system.
That is to say, the historical volume in the android system-earphone mode, the historical volume in the android system-playback mode, the historical volume in the ios system-earphone mode, and the historical volume in the ios system-playback mode can be separately acquired and clustered.
In step S12, the acquired historical sound volume is processed using a clustering algorithm.
The clustering algorithm may be, for example, a DBSCAN algorithm, a GMM algorithm, a CFSFDP algorithm, and the like.
In the implementation process, the clustering algorithm can start clustering processing after the obtained historical volume data are more than N, so that the clustering processing based on enough historical volume samples can be ensured, and the accuracy and the credibility of the clustering processing result are ensured. Moreover, as long as the acquired historical volume data is continuously updated, the clustering algorithm can continuously update the clustering result according to the acquired historical volume data, so that the clustering result can reflect the latest volume preference of the user.
Moreover, in this step, the historical volume in the android system-headphone mode, the historical volume in the android system-playback mode, the historical volume in the ios system-headphone mode, and the historical volume in the ios system-playback mode may be separately clustered, so as to better satisfy the audio usage scenario of the user.
In step S13, a default volume corresponding to the user is determined based on the class with the smallest average value after the clustering process, where the default volume is used to indicate the volume used when the user triggers the next audio playing event.
In the present disclosure, the user triggering the next audio play event refers to an audio play event caused by the user closing the application playing audio and starting the application playing audio again.
In this step, the class with the minimum mean value after the clustering process may be selected first, and then, when the user triggers the next audio playing event, the mean value of the selected class is determined as the default volume corresponding to the user.
Or, the class with the minimum mean value after the clustering process may be selected first, and then, when the user triggers the next audio playing event, the minimum value between the mean value of the selected class and the default media volume of the system may be determined as the default volume corresponding to the user. That is, if the default media volume of the system is smaller than the average value of the selected class, the default media volume of the system is determined as the default volume corresponding to the user when the user triggers the next audio playing event; if the default volume of the media is larger than the average value of the selected class, the average value of the selected class is determined as the default volume corresponding to the user when the user triggers the next audio playing event.
In addition, if the historical volumes in the headphone mode and the play-out mode are separately obtained and clustered, in the previous step, if the user triggers the next audio playing event to be in the headphone mode, the volume is automatically adjusted based on the clustering result in the headphone mode, and if the user triggers the next audio playing event to be in the play-out mode, the volume is automatically adjusted based on the clustering result in the play-out mode. The same is true for the android system and the ios system.
By adopting the technical scheme, since the historical volume used by the user in the historical audio playing event is firstly obtained, then the obtained historical volume is processed by using a clustering algorithm, and then the default volume corresponding to the user is determined based on the class with the minimum mean value after the clustering processing, and the default volume is used for indicating the volume used by the user when the user triggers the next audio playing event, so that the automatic adjustment of the playing volume can be realized when the user triggers the next audio playing event, thereby ensuring that the audio can be played with a relatively proper volume, avoiding negative consumption experience caused by overlarge playing volume in partial using scenes (such as a quiet environment scene, a public occasion scene, a scene with earphones and the like) and psychological burden of the user playing the audio in the scene, for example, ensuring that the playing volume cannot be overlarge under the condition of wearing earphones so as not to damage ears, ensure that the volume of the externally-emitted sound can be clearly heard and does not disturb people around under the condition of a quiet public place.

As shown in fig. 2, the automatic volume adjusting apparatus includes: an obtaining module 21, configured to obtain a historical volume used by a user in a historical audio playing event; the processing module 22 is used for processing the historical volume acquired by the acquisition module by using a clustering algorithm; and the determining module 23 is configured to determine a default volume corresponding to the user based on the class with the smallest average value after the clustering process, where the default volume is used to indicate a volume used when the user triggers a next audio play event.
