Detailed Description
In order to make the technical problems, technical solutions and technical effects of the present invention more clear and complete, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
It should be noted that, in the embodiment of the present invention, the "first" and the "second" are only used to distinguish a plurality of the same technical features, and are not to be construed as limiting the technical features.
Example one
Fig. 2 is a schematic structural diagram of an audio processing system according to an embodiment of the invention. As shown in fig. 2, the sound source processing system includes a client 21, a sound source management module 22, a sound playing module 23, a first sound card 24(1), and a second sound card 24 (2).
In the embodiment of the present invention, the client 21 is a client APP capable of playing audio data, and may be installed on a terminal for information interaction. For example, heaven-day silence, hundredth navigation, etc. installed on a smartphone.
In the embodiment of the present invention, the first sound card 24(1) is a physical sound card capable of producing sound, and the second sound card 24(2) is a virtual sound card incapable of producing sound.
Based on the sound source processing system shown in fig. 2, an embodiment of the invention provides a sound source processing method. Fig. 3 is a signaling flow diagram illustrating a sound source processing method according to an embodiment of the present invention. As shown in fig. 3, the method comprises the steps of:
s301, the client 21 sends an application request for applying the ID to the sound source management module 22:
the identification ID is used to identify the correspondence between the sound source and the client 21, for example: the ID may be a string carrying client information, audio data information, and the like. The sound source is a file carrying audio data, and can also be understood as audio data or an application carrying audio data, and the like.
As an example, the client 21 may send an application request for applying the identification ID to the sound source management module 22 by a sound type.
S302, the sound source management module 22 feeds back the identifier ID to the client 21 according to the first preset rule:
for example, the first preset rule may be that the sound source management module generates different identification IDs according to the type of the client, for example, the client is a heaven-day still listening, and the sound source management module 22 generates an identification ID corresponding to the heaven-day still listening according to the type of the client, where the identification ID may be a character string carrying client information and audio data information played by the client.
S303, the client 21 sends a play request to the sound source management module 22 through the ID:
the play request is used for requesting to play the audio data.
S304, after receiving the play request from the client 21, the sound source management module 22 issues a play notification to the client 21:
the playing notification is used for indicating that the audio source allows playing or forbids playing of the audio data.
It should be noted that, when no sound source is playing the audio data currently, in a normal situation, the sound source management module 22 will issue a play notification allowing to play the audio data to the client 21 after receiving the play request of the client 21.
S305, after receiving the play notification allowing the audio data to be played and sent by the sound source management module, the client 21 sends a play instruction and the audio data to the sound playing module 23:
it should be noted that the play instruction includes an identification ID.
S306, after receiving the playing instruction and the audio data sent by the client 21, the sound playing module 23 sends a registered sound source message to the sound source management module 22:
the registered sound source message comprises an identification ID and audio data corresponding to the identification ID.
It should be noted that the purpose of the sound playing module 23 sending the registered sound source message to the sound source management module 22 is that the sound playing module 23 inquires the sound source management module 22 whether the audio data received by it is allowed to be played.
S307, after receiving the registered sound source message, the sound source management module 22 determines whether the sound source corresponding to the identifier ID is allowed to be played according to a second preset rule, if yes, steps S308 to S309 are executed, and if no, steps S310 to S312 are executed:
as an example, the second preset rule may be, for example: and taking the sound type as a parameter, such as the emergency degree of the sound type and the application precedence relationship. Thus, the request for playing may include sound type information.
As an example, the second preset rule may be an application-first rule, and if the first client applies for the second client earlier, the sound source management module allows the sound source to play and prohibits the second sound source from playing.
As another example, the second preset rule may be that the first client has a higher priority than the second client, and thus the sound source management module allows sound source playing and prohibits the second sound source playing.
As yet another example, the second preset rule may be that the first client and the second client are capable of speaking simultaneously, and then the sound source management module allows the sound source and the second sound source to play.
S308, the sound source management module 22 sends the information for connecting the sound source to the sound playing module 23:
in the embodiment of the invention, the initial state of the audio output channel of the sound source is defaulted to the off state. Therefore, when it applies for playing, its audio output channel is in a disconnected state, and therefore, after determining that it is allowed to play audio data, the sound source management module 22 sends connection information to the sound playing module 23 to control the audio output channel connected to the sound source.
S309, after receiving the connection sound source information, the sound playing module 23 sends the audio data to the first sound card 24(1), so that the sound source sounds.
S310, the sound source management module 22 sends a play notification for instructing the client to prohibit playing the audio data to the client.
S311, the sound source management module 22 sends the information that the sound source is not connected to the sound playing module 23:
s312, the sound playing module 23 sends the audio data to the second sound card 24(2) so that the sound source does not generate sound.
The foregoing is a detailed implementation of the sound source processing system and method provided in the first embodiment of the present invention. In this embodiment, after the audio data is transmitted to the sound playing module, the sound playing module does not transmit the audio data to the sound card immediately, but transmits the registered sound source information to the sound source management module, and then the sound source management module may determine whether the sound source corresponding to the identifier ID is allowed to be played according to the second preset rule, and feed back information about whether the sound source is connected to the sound playing module according to the determination result.
In this way, in the sound source processing method provided by the present invention, whether the sound source is sounded or not is controlled by the sound source management module, and even if the sound source whose sound is prohibited transmits audio data to the sound playing module, that is, even if the sound playing module runs a red light, the sound source management module still determines whether the sound source corresponding to the identification ID is permitted to play, so as to control the sound production of the sound source.
The foregoing is a detailed implementation of the sound source processing system and method provided in the first embodiment of the present invention. In the sound source processing system, only one client capable of playing audio data is included. As another embodiment of the present invention, the sound source processing system may include a plurality of clients capable of playing audio data. Aiming at a sound source processing system comprising a plurality of clients capable of playing audio data, the sound source processing system comprises two situations: the first method comprises the following steps: when one client capable of playing audio data applies for playing the audio data, other clients capable of playing the audio data are not playing the audio data, and the second type is: when one client capable of playing the audio data applies for playing the audio data, at least one of the other clients capable of playing the audio data is playing the audio data. The sound source processing method for the first case is the same as the sound source processing method provided in the first embodiment, and the following focuses on the sound source processing method for the second case.
When the sound source processing system includes a plurality of clients capable of playing audio data, one client capable of playing audio data applies for playing audio data, and at least one of the other clients capable of playing audio data is playing audio data, please refer to embodiment two for a specific implementation of the sound source processing method corresponding thereto.
Example two
Fig. 4 is a block diagram of an audio processing system according to a second embodiment of the invention. As shown in fig. 4, the sound source processing system includes a first client 41(1), a second client 41(2), a sound source management module 42, a sound playing module 43, a first sound card 44(1), and a second sound card 44 (2).
For convenience of description, the sound emitted by the first client is referred to as a first sound source, and the sound emitted by the second client is referred to as a second sound source.
The first client 41(1) is set to apply for playing the audio data, and the second client 41(2) is playing the audio data. In this case, a signaling flow diagram of the audio source processing method is shown in fig. 5, which includes the following steps:
s501, the first client 41(1) sends an application request for applying for the first identifier ID to the sound source management module 42:
s502, the sound source management module 42 feeds back the first identifier ID to the first client 41(1) according to the first preset rule:
s503, the first client 41(1) sends the playing request to the sound source management module 42 through the first identifier ID:
s504, after receiving the play request from the first client 41(1), the sound source management module 42 issues a play notification to the first client 41 (1):
since the current second client 41(2) is playing the audio data, after the sound source management module 42 receives the playing request of the first client 41(1), the sound source management module 42 will determine whether to allow the first sound source to play according to the second preset rule, and if the first sound source is allowed to play, the sound source management module 22 issues a playing notification that the audio data is allowed to be played to the first client 41 (1). If the first client 41(1) is not allowed to play the audio data, the sound source management module 22 issues a notification to the first client 41(1) to prohibit playing the audio data.
In the embodiment of the present invention, it is exemplified that the first client 41(1) is allowed to play the audio data and the second client 41(2) is prohibited to play the audio data according to the second preset rule.
S505, after receiving the notification allowing the audio data to be played and sent by the sound source management module 42, the first client 41(1) sends a play instruction and the first audio data to the sound playing module 43:
s506, after receiving the playing instruction and the first audio data sent by the first client 41(1), the sound playing module 43 sends a registered sound source message to the sound source management module 42:
s507, after receiving the registered sound source message, the sound source management module 42 determines whether the first sound source corresponding to the first identifier ID is allowed to be played according to a second preset rule, if yes, steps S508 to S510 are executed, and if no, steps S511 to S513 are executed:
s508, the sound source management module 42 sends feedback information to the sound playing module 43, where the feedback information includes information of connecting the first sound source and disconnecting the second sound source:
s509, after receiving the feedback information, the sound playing module 43 sends the first audio data of the first client 41(1) to the first sound card 44(1) to make the first sound source corresponding to the first client generate sound, and sends the second audio data of the second client 41(2) to the second sound card 44(2) to make the second client 44(2) not generate sound.
S510, the sound source management module 42 sends a play notification to the second client 41(2) for instructing the second client 41(2) to prohibit playing the audio data:
it should be noted that, in the embodiment of the present invention, step S510 may be executed before step S508, or may be executed after step S508.
S511, the sound source management module 42 sends a play notification for instructing the first client to prohibit playing the audio data to the first client.
S511, the sound source management module 42 sends the information that the first sound source is not connected to the sound playing module 43:
s513, the sound playing module 43 sends the first audio data of the first client 41(1) to the second sound card 44(2), so that the first sound source of the first client does not generate sound.
In addition, when the sound source processing system comprises a plurality of clients capable of playing audio data and a plurality of first sound cards, corresponding relations between the clients capable of playing the audio data and the first sound cards can be set in the sound source management module, and according to the corresponding relations, the sound playing module transmits the audio data of the clients capable of playing the audio data to the first sound cards. In addition, the user can change the corresponding relation between the client side arranged in the sound source management module and the first sound card according to the requirement, and based on the change, the user can dynamically change the first sound card corresponding to the client side capable of playing the audio data, namely, the output channel of the client side capable of playing the audio data.
In the embodiment of the present invention, the connection and disconnection of the sound output path (i.e., the connection path between the client and the first sound card) is not limited to a software manner, and may also be implemented by switching a hardware channel. For example, the audio data streams of the client are respectively output by using two IISs (corresponding to two physical sound cards). At this time, the client can be connected to a peripheral circuit with audio channel selection and mixing functions, and the circuit is controlled to achieve connection and disconnection of the client output path.
It should be noted that the second embodiment is described by taking two clients as an example. In fact, as an extension of the embodiment of the present invention, the sound source processing system may include three or more clients. When three or more clients are included, the corresponding sound source processing method is similar to the processing method including two clients, and is not described in detail here.
The above is a specific implementation of the sound source processing method provided in the first embodiment and the second embodiment of the present invention. In this embodiment, the audio playing module and the sound source management module directly perform information interaction. As another embodiment of the present invention, the same effect can also be achieved by indirectly performing information interaction between the sound playing module and the sound source management module, which is specifically referred to in the third embodiment.
