Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
These and other aspects of embodiments of the invention will be apparent with reference to the following description and attached drawings. In the description and drawings, particular embodiments of the invention have been disclosed in detail as being indicative of some of the ways in which the principles of the embodiments of the invention may be practiced, but it is understood that the scope of the embodiments of the invention is not limited correspondingly. On the contrary, the embodiments of the invention include all changes, modifications and equivalents coming within the spirit and terms of the claims appended hereto.
The audio data transmission method in the embodiment of the invention is applied to the mobile terminal, and the mobile terminal is an electronic device such as a mobile phone, a tablet computer and the like. The mobile terminal may be connected to a bluetooth receiver, such as a bluetooth headset, using both the classic Bluetooth (BT) and low energy Bluetooth (BLE) protocols.
Referring to fig. 1, a method for transmitting audio data according to a first embodiment of the present invention includes steps S11-S14.
Step S11, obtaining audio data in the application system in real time, extracting each sub-audio data in the audio data according to the difference of sound producing bodies, and determining a sound producing body identifier corresponding to each sub-audio data.
Step S12, querying a delay type of each sub-audio data from a preset data delay type table according to the utterance body identifier, where the delay type includes a first type and a second type, and a real-time requirement of the data of the first type is higher than that of the data of the second type.
The mobile terminal in this embodiment is equipped with at least one Application (APP), preferably a gaming application, generally referred to as an FPS (first person shooter) type game. For example, games such as "peace elite", "elite troops", etc. are currently popular. The audio data of the application system in the using process comprises various sub audio data, such as audio data of footstep sound, car sound, gunshot sound, background music, game sound effect and the like. Each sub audio data has different sound producing bodies, such as human bodies, firearms and automobiles on an operation interface in application, and a background music module and a sound effect module in an application system.
In the application system, sounds such as footstep sounds and gunshot sounds which influence the player to judge the movement of the local player are important to the success or failure of the game, and the user has high requirements on the real-time performance of receiving the data. And the real-time requirement for data such as background music, game sound effects and the like is low. Therefore, in the present embodiment, the audio data in the application system is mainly divided into two types, wherein the real-time performance requirement of the first type of data is higher than that of the second type.
The sub-audio data of each sound producing body in the audio data extracted by the mobile terminal is, for example, gunshot audio data, footstep audio data, background music response data, and the like generated by an application system. The mobile terminal is pre-stored with a data delay type table, and the data delay type table comprises each sounding body identifier and a corresponding type. And the mobile terminal inquires the type of each acquired sub audio data in the data delay type table.
And step S13, sending the sub audio data belonging to the first type to a Bluetooth headset connected with the mobile terminal through a low-power Bluetooth protocol.
And step S14, transmitting the sub audio data belonging to the second type to the Bluetooth headset through a classic Bluetooth protocol.
And after determining the type of each sub audio data, the mobile terminal sends the sub audio data belonging to the first type to a Bluetooth earphone connected with the mobile terminal through a low-power Bluetooth protocol. The sub audio data of the first type has higher requirement on real-time performance and low requirement on bandwidth, and the sub audio data of the first type is sent to the Bluetooth headset through a low-power Bluetooth protocol. The communication mode of the low power consumption bluetooth protocol, which is the GATT protocol, is a fixed interval mode, and can be as low as 7.5ms for one packet, that is, whether data exists or not, the bluetooth of the mobile terminal must send data to the opposite terminal device when the fixed interval expires. Therefore, compared with the classic Bluetooth, the low-power Bluetooth has the advantages of high real-time performance, low time delay and the like.
The audio data of the second type has low requirement on the delay performance and high requirement on the bandwidth, so that the sub-audio data belonging to the second type is sent to the Bluetooth headset connected with the sub-audio data through the classic Bluetooth protocol. The classic bluetooth protocol is, for example, the A2DP protocol, and the A2DP protocol has a large bandwidth to achieve high energy efficiency performance of data transmission.
In this embodiment, the audio data in the application system is obtained in real time, each sub-audio data in the audio data is extracted according to the difference of the sound generating bodies, and the sound generating body identifier corresponding to each sub-audio data is determined. And inquiring the type of each audio data according to the identification of the sounding body, and sending the audio data by adopting different Bluetooth protocols according to different real-time requirements. The sub audio data in the application system is mainly divided into two types, wherein the time delay requirement of the self audio data of the first type is higher than that of the self audio data of the second type, so that the sub audio data of the first type is sent to a Bluetooth earphone end through a low-power-consumption Bluetooth protocol to ensure the timeliness of data transmission, and the sub audio data of the second type is sent to the earphone end through a classic Bluetooth protocol to ensure the high efficiency of data transmission.
Referring to fig. 2, a method for transmitting audio data according to a second embodiment of the present invention includes steps S21-S24.
Step S21, obtaining audio data in the application system in real time, and extracting sub-audio data and corresponding sound-generating body identifier in each data packet in the audio data.
In this embodiment, the application system defines a plurality of sound producing units, and each sound producing unit may produce corresponding sub-audio data in the application running process. The sound producing body is, for example, a human body, a gun, a car on an operation interface in an application, and a background music module, a sound effect module and the like in an application system, and the sub audio data produced by the sound producing body is footstep sound data, gun sound data, car sound data, background music data, sound effect data and the like. The sub-audio data generated by each sounding body in the application system exists in the form of a separate data packet, and the data packet also contains the sounding body identification of the sounding body. The sound-producing body identification is the only identification used by the mobile terminal for identifying the sound-producing body. The audio data of the application system acquired by the mobile terminal are data packets corresponding to the plurality of sounding bodies, and the sub-audio data and the sounding body identifications are extracted after the mobile terminal acquires the data packets.
Step S22, querying a delay type of each sub-audio data from a preset data delay type table according to the utterance body identifier, where the delay type includes a first type and a second type, and a real-time requirement of the data of the first type is higher than that of the data of the second type.
The mobile terminal stores a data delay type table, and the data delay type table comprises each sounding body identifier and a delay type corresponding to the sounding body identifier. In the present embodiment, the sub-audio data generated by each sounding body in the application system is divided into two types, i.e., a first type and a second type. Wherein the first type of sub audio data has a higher real-time requirement than the second type. In particular implementations, the first type of sub-audio data includes, but is not limited to, sub-audio data generated by a human, a firearm, or an automobile; the second type of sub audio data includes, but is not limited to, background music, sound effect data.
And step S23, sending the sub audio data belonging to the first type to a Bluetooth headset connected with the mobile terminal through a low-power Bluetooth protocol.
When the mobile terminal sends audio data to the bluetooth headset, because of the limitation of bluetooth bandwidth, the audio data stream needs to be encoded and compressed, and common encoding has SBC algorithm and the like. When the method is implemented specifically, the mobile terminal encodes and compresses the sub-audio data belonging to the first type through an SCB algorithm, and sends the encoded and compressed sub-audio data to the Bluetooth headset through a GATT protocol. The GATT protocol is a low-power-consumption Bluetooth protocol, and has the advantages of high real-time performance and low time delay during data transmission.
And step S24, sending the sub audio data of the second type to the Bluetooth headset through a classic Bluetooth protocol.
In specific implementation, the mobile terminal encodes and compresses the sub-data of the second type by an SCB algorithm, and sends the sub-data to the bluetooth headset by an A2DP protocol. The A2DP protocol is a classic bluetooth protocol, which has a large bandwidth and ensures high energy efficiency of data transmission.
And the Bluetooth earphone decodes and plays the sub audio data in sequence according to the time sequence of the arrival of the sub audio data. If the Bluetooth headset receives the sub-audio data transmitted by the A2DP protocol and the GATT protocol at the same time, the Bluetooth headset preferentially decodes and plays the sub-audio data transmitted by the GATT protocol, and then decodes and plays the sub-audio data transmitted by the A2DP protocol, so as to ensure the timeliness of the first type data transmission.
In this embodiment, the application system in the mobile terminal packages the sub-audio data not generated by each sounding body and the identifier of the sounding body into a data packet. The mobile terminal obtains each data packet of the application system, extracts the sub audio data and the sounding body identification in the data packet, and determines the time delay type of the sub audio data according to the identification. Sub audio data with high real-time requirement is sent to a Bluetooth earphone by a GATT protocol, so that the timeliness of the data obtained by a user is guaranteed, and the user experience is improved; meanwhile, the sub audio data with low real-time requirement is sent to the Bluetooth headset by the A2DP protocol, so that high energy efficiency of data output is ensured.
Referring to fig. 3, a method for transmitting audio data according to a third embodiment of the present invention includes steps S31-S34.
Step S31, audio data in the application system are obtained in real time, and the audio data are classified through a neural network model, so that sub-audio data of each sounding body in the audio data and a corresponding sounding body identifier are obtained.
In this embodiment, the audio data output by the application system is a sound data mixture generated by various sound generators, and compared with the second embodiment, the application system does not need to perform a packing process on sub-sound data generated by each sound generator. In this embodiment, after acquiring the audio data in the application system, the mobile terminal separates the audio data through the neural network model to obtain sub-audio data generated by each sound generating body and a corresponding sound generating body identifier. The specific steps of classifying the audio data through the neural network model comprise:
step S311, establishing a neural network model, and training the neural network model by using label data, wherein the label data comprises a plurality of sub-audio data with sound-producing body identifications;
step S312, the trained neural network model classifies the audio data to obtain sub-audio data of each sounding body in the audio data and a corresponding sounding body identifier.
In this embodiment, the neural network model is trained through each sub audio data with the sounding body label, and the trained neural network model can be used to classify the audio data output by the application system, so as to output each sub audio label data and the corresponding sounding body identifier.
The neural network model may adopt a model in an advanced technology, for example, a DNN model (deep neural Networks, deep neural network model) may be adopted, the DNN may be divided according to positions of different layers, and the neural network layer inside the DNN may be divided into three layers, an input layer, a hidden layer and an output layer. In specific implementation, a DNN model is constructed and trained, the DNN model can adopt a tensoflow frame to train audio data so as to determine parameters of the DNN model, and the trained DNN model is used for classifying the audio data.
Step S32, querying a delay type of each sub-audio data from a preset data delay type table according to the utterance body identifier, where the delay type includes a first type and a second type, and a real-time requirement of the data of the first type is higher than that of the data of the second type.
In this embodiment, each sound generator in the application system generates sub-audio data, such as footstep sound data, gunshot sound data, car sound data, background music data, and sound effect data, which are divided into two types of time delay. Wherein the first type of sub-audio data includes, but is not limited to, sub-audio data generated by a human body, a firearm, a car, etc.; the second type of sub audio data includes, but is not limited to, background music, sound effect data, and the like. The data type of each sub audio data is determined according to the data type of the sounding body obtained by table lookup.
And step S33, sending the sub audio data belonging to the first type to a Bluetooth headset connected with the mobile terminal through a low-power Bluetooth protocol.
And step S34, sending the sub audio data of the second type to the Bluetooth headset through a classic Bluetooth protocol.
In this embodiment, program development is not required for the application, and the mobile terminal directly classifies the audio data output by the application system through the neural network, so as to obtain each sub-audio data and the corresponding sounding body identifier, and determines the data type of each sub-audio data according to the table lookup of the sounding body identifier.
