Detailed Description
Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.
During the process of playing audio by the application program, the application program can play audio only after AudioFocus is obtained, so that the control of audio playing depends on the third party application. In addition, since a plurality of application programs which have audio playing functions and have all obtained AudioFocus may be running at the same time, a certain application program may suddenly play audio, so that audio track playing switching is not flexible and accurate. Therefore, in order to realize that the audio switching does not depend on a third party application and fine granularity control of specific audio playing, the embodiment of the application provides an audio track playing control method, an audio track playing control device, an electronic device and a readable storage medium. Further, the silence of all tracks currently being played is controlled. And finally, acquiring at least one target client information corresponding to the at least one target identifier from an information table recorded with the client information in operation, and controlling the audio track playing sound associated with the at least one target client information. The trusted application controls to enter a single sound broadcasting mode, under the condition that the mode is opened, a single specific application or a plurality of appointed applications are controlled to play voice according to recorded client information, other applications play voice in a mute mode, after the single sound broadcasting mode is exited, other applications can normally play voice, the audio switching is carried out independent of a third party application, and the fine granularity control is carried out on the appointed audio track so as to improve the accuracy of the audio switching playing.
The embodiment of the application provides a method for controlling audio track playing, as shown in fig. 1, which comprises the following steps:
101. When the trusted application is detected to start a single-sound playing mode, a play list is obtained, wherein the play list comprises at least one target identifier, and each target identifier in the at least one target identifier is an identity identifier of a client which is specified by the trusted application and has playing authority.
The trusted application refers to an application program with application control authority developed by a factory, and specifically can be a voice assistant application program. And the audio playing control system acquires a play list set by the trusted application when detecting that the trusted application starts a single-sound playing mode. It should be noted that at least one target identifier is stored in the playlist, where each target identifier is used to indicate an identity of a client specified by the trusted application and having playing rights. That is, the target identifier recorded in the playlist is an identifier of the application client capable of playing sound in the single-sound playing mode. In the embodiment of the application, the client can be a music playing application, a video playing application, an audio-video call application, a voice dialogue application and the like. In the case where the single-sound broadcasting mode is on, the audio broadcasting control system controls a single specific application or a specified plurality of applications to broadcast voices according to the fine granularity of the playlist, and even if the application not in the playlist is broadcast, the application is broadcast in a silent broadcasting mode without sound.
102. And controlling the mute of all the audio tracks currently being played.
In the embodiment of the application, in order to ensure that when the single-sound broadcasting mode is on, other applications which are not allowed to play sound are in a non-playing state, or even if the application is played, the application is played in a mute playing mode without sound. Therefore, the audio playback control system needs to control silence of all tracks currently being played (pause of track playback or play of a track in a silent playback mode) in the case where the mono playback mode is on. For example, when a music client plays music, a user starts a trusted application (e.g., wakes up a voice assistant), and the trusted application such as the voice assistant starts a single sound play mode according to the current running scenario. When the trusted application starts a single-sound playing mode, the audio playing control system controls the audio track currently being played to be mute, and audio data of the trusted application such as a voice assistant is played through the newly-built audio track. Meanwhile, the audio playing control system finds out the client information which is allowed to be played in the single-sound playing mode in the running client according to the play list, and plays the sound of the audio track associated with the client information.
103. And acquiring at least one target client information corresponding to the at least one target identifier in an information table, and controlling the audio track playing sound associated with the at least one target client information, wherein the information table records the client information in operation.
Wherein, the information table records the client information in operation. Specifically, after a user starts an application client, the client may appear in the running process. At this time, the audio playback control system creates an audio track to play the audio sound of the audio track associated with the application client. At the same time, the audio playing control system needs to actively record the relevant information of the audio track associated with the client, such as audio track volume, application package name (i.e. application package name), application process, client identifier (information identifier), and the like, and record the relevant information as client information in an information table. Further, if the application client stops running, the client information corresponding to the application client is deleted from the information table. In the embodiment of the application, in order to accurately determine at least one target client permitted to play by the trusted application from a plurality of clients in operation, the audio play control system needs to compare the information identifier in each client information in the information table with the target identifier recorded in the play list. And further, according to the comparison result, determining at least one target client information hit in the playlist in the information table, and controlling the audio track playing sound associated with the at least one target client information.
The method provided by the embodiment of the application can acquire the play list which is appointed by the trusted application and allowed to be played when the trusted application is detected to start the single-sound play mode, wherein each target identifier stored in the play list is the identity identifier of the client which is appointed by the trusted application and has play authority. Further, the silence of all tracks currently being played is controlled. And finally, acquiring at least one target client information corresponding to the at least one target identifier from an information table recorded with the client information in operation, and controlling the audio track playing sound associated with the at least one target client information. The trusted application controls to enter a single sound broadcasting mode, under the condition that the mode is opened, a single specific application or a plurality of appointed applications are controlled to play voice according to recorded client information, other applications play voice in a mute mode, after the single sound broadcasting mode is exited, other applications can normally play voice, the audio switching is carried out independent of a third party application, and the fine granularity control is carried out on the appointed audio track so as to improve the accuracy of the audio switching playing.
The embodiment of the application provides a method for controlling audio track playing, as shown in fig. 2, which comprises the following steps:
201. In response to a user's play request, determining a designated client, creating an audio track, associating the audio track with the designated client, and controlling the created audio track to play audio from the designated client.
In the embodiment of the application, the trusted device is taken as a voice assistant, and the user wakes up the voice assistant to perform a dialogue with the voice assistant so as to enable the voice assistant to start an application scene of a single-sound playing mode. The audio playback control system may simultaneously control the plurality of clients that are running to associate a plurality of track playback sounds before the voice assistant does not turn on the single sound playback mode. As shown in fig. 3, there are a plurality of stages of audio playback, including track preparation, mixing, writing pcm, etc., and the control of the audio playback can be performed at different stages of audio playback. When the application client tries to play the audio, the audio playing control system creates an audio track for the application client, associates the audio track with the audio corresponding to the application client, and enters various stages of sound playing to realize playing of audio sounds. Before the voice assistant does not start the single-sound playing mode, the audio of the music application, the voice broadcast, the video application and the like can be selected to be played simultaneously. For example, when a music client is running, its associated track a is playing music 01, the user next turns on the game client, creates track B to play music 02, and before the single sound play mode is not turned on, the audio play control system may control track a and track B to play music 01 and music 02 simultaneously so that the user may hear the sounds of music 01 and music 02 simultaneously.
In the actual running process, after the user enters the appointed client, a playing request can be initiated to play the playing audio appointed by the appointed client. Specifically, the audio playing control system responds to a playing request of a user, determines a designated client to be subjected to sound playing indicated by the playing request, and then creates an audio track to play the audio of the client designated by the user. That is, each time a user opens an application client, the audio playing control system needs to create an audio track to associate with the application client, so as to play the audio sound corresponding to the application client.
It should be noted that, considering that some application clients are trusted applications through trust authentication, they need to perform a dialogue with the user to obtain the user intention, so if the specified client is a trusted application through trust authentication, the trusted application will identify and determine the voice feedback audio or voice dialogue audio required by the responding user by obtaining the voice information of the user, and use the voice feedback audio or voice dialogue audio as the specified audio, and the audio playing control system controls the newly-built audio track to play the specified audio. For example, the user initiates a voice instruction with a voice keyword to wake up a voice assistant, which determines the audio associated with the keyword from the keyword (e.g., "I am asking what is needed for help. And the third party application which does not pass the trust authentication does not need to be in dialogue with the user to determine the user intention, so if the appointed client is the third party application which does not pass the trust authentication, the third party application identifies the appointed audio by acquiring the operation information of the user, and the appointed audio is determined according to the operation information of the user, so that the audio playing control system controls the newly-built audio track to play the appointed audio. For example, the user enters a certain music client a, which takes music 03 as specified audio by clicking on a link of music 03 to enter a play entry for music 03.
202. The information identification, audio volume, application package name, application process information, etc. of the specified client are read as the client information of the specified client, and the client information of the specified client is recorded in an information table.
In order to determine the client corresponding to each track and the playing process of each track, the audio playing control system records the relevant information of the recording track as corresponding client information and stores the relevant information in an information table. The relevant information of the audio track, namely the client information, includes audio track volume, application package name (namely application package name), application process, information identification (client identification) and the like. In the actual running process, each time a user starts an application client, the client will appear in the application process, if the client needs to play sound, the audio play control system will create an audio track to associate with the client, and use the created audio track to play the audio sound indicated by the application client. Meanwhile, the audio playing control system needs to actively record relevant information of the newly-built audio track, and records the information as client information in the information table, so that the audio playing control system can restore or maintain the playing state of the audio track associated with the client information stored in the information table according to the information table.
203. When the trusted application is detected to initiate a single sound play mode, a playlist is obtained and all tracks currently being played are controlled to be muted.
In a scenario where a user wakes up a voice assistant to talk with the voice assistant, the voice assistant may turn on a single-sound play mode. When the audio playing control system detects that the trusted application starts a single-sound playing mode, all audio tracks currently being played are controlled to be mute, and simultaneously, in response to an instruction of a new audio track initiated by the trusted application, a new audio track is associated with the voice assistant, so that the voice assistant can communicate with a user through playing of the new audio track and voice feedback audio or voice dialogue audio, and user intention is obtained. Next, the audio playback control system needs to obtain a playlist set by the trusted device in order to determine which clients are clients that the trusted device is allowed to play. It should be noted that at least one target identifier is stored in the playlist, where each target identifier is used to indicate an identity of a client specified by the trusted application and having playing rights. That is, the target identifier recorded in the playlist is an identifier of the application client capable of playing sound in the single-sound playing mode. The subsequent audio playing control system can determine the target client information which is allowed to be played in the single-sound playing mode in the information table according to the play list, and then play the sound of the audio track associated with the target client information.
Specifically, the audio playback control system may send an instruction to the trusted application to obtain the playlist, the trusted application reading the playlist in the storage location in response to the instruction to obtain the playlist, sending the playlist to the audio playback control system to cause the audio playback control system to obtain the playlist. Further, the audio playback control system may control the muting of all tracks currently being played in a manner that pauses the playback of the tracks, as well as modulating the volume of the tracks. In the actual operation process, for all the tracks being played, the audio playing control system needs to read the volume of the tracks corresponding to each track in all the tracks, and at least one designated track with the volume greater than the volume threshold is determined in all the tracks. It should be noted that, the volume threshold is used to indicate the volume 0 of the audio track corresponding to the mute state, that is, the audio play control system needs to determine the designated audio track that is playing the sound from all audio tracks. Further, the audio track volume of at least one designated audio track is controlled to be reduced to a volume threshold value of 0, or the playing state of at least one designated audio track is controlled to be in a pause playing state, so that the mute of all audio tracks currently being played is realized.
204. Traversing all the client information stored in the information table, and comparing at least one target identifier with the information identifier included in each piece of client information in all the client information to obtain a comparison result corresponding to each piece of client information.
In the embodiment of the application, the information table stores the client information of all the currently running applications, wherein the tracks corresponding to some client information are tracks which are allowed to be played in the single-sound playing mode by the trusted application, and the tracks corresponding to some client information are tracks which are not allowed to be played in the single-sound playing mode by the trusted application. Therefore, in order to accurately play the sound of the audio track allowed to be played by the trusted application from the existing audio track, the audio play control system needs to read the information identifier corresponding to each piece of client information in the information table and compare the information identifier with at least one target identifier stored in the play list. For example, the information table stores client information corresponding to three audio tracks, and the information identifier corresponding to each client information is respectively [ a music ], [ B game ], [ C text input application ]. The target identifications stored in the playlist set by the trusted application are [ a music ] and [ C text entry application ]. And comparing the information identifier (A music), the game (B) and the text input application (C) with the target identifiers (A music) and the text input application (C) to determine whether the target identifiers comprise the same target identifier as the information identifier. If the comparison result corresponding to the client information shows that at least one target identifier in the playlist comprises the same target identifier as the information identifier, the track associated with the client information is the track which is allowed to be played by the trusted application, and a comparison result for indicating that the client information hits the playlist is correspondingly generated. If the comparison result shows that at least one target identifier in the playlist does not comprise the target identifier identical to the information identifier, the audio track associated with the client information is not the audio track allowed to be played by the trusted application, and a comparison result for indicating that the client information does not hit the playlist is correspondingly generated.
205. And extracting at least one piece of client information of which the comparison result indicates that the playlist is hit from all pieces of client information as at least one piece of target client information, and controlling the audio track associated with the at least one piece of target client information to play sound.
In the embodiment of the application, for each piece of client information in all pieces of client information recorded in the information table, if the comparison result indicates that the piece of client information hits the play list, the audio play control system controls the associated audio track play sound. In particular, it is contemplated that when muting is an audio playback control system may mute in both a pause state that controls the playback state of the audio track or a decrease in the audio track volume of the control audio track to a volume threshold.
