Based on the above intelligent terminal hardware structure and communication network system, various embodiments of the present application are provided.

Referring to fig. 3, for the audio processing method provided in the embodiment of the present application, the method may be applicable to a situation where an audio sampling rate of audio data is adjusted, and the method may be executed by an audio processing apparatus provided in the embodiment of the present application, where the apparatus may be implemented in a software and/or hardware manner, and optionally, the apparatus may be specifically an intelligent terminal or the like. The smart terminal may be implemented in various forms, and the smart terminal described in this embodiment may include terminals such as a mobile phone, a tablet computer, a notebook computer, a palm computer, a Personal Digital Assistant (PDA), a Portable Media Player (PMP), a wearable device, a smart band, and a pedometer. In this embodiment, taking an execution subject of the audio processing method as an example of an intelligent terminal, the method includes:

step S1: and acquiring scene information.

Optionally, the scene information may be used to represent a current scene of the intelligent terminal, and optionally, whether the intelligent terminal is in a low-delay-demand scene such as a foreground running game application, or whether the intelligent terminal is in a high-quality audio-demand scene such as a foreground running music application, or the like. Optionally, the scene information may specifically include a scene type, and the like, for example, the intelligent terminal may obtain the scene information by obtaining foreground-running application information and then obtaining the scene information from the foreground-running application information, or may obtain the scene information according to an operation input by a user by obtaining the operation input by the user.

Optionally, the step S1 includes:

responding to the first preset operation, and outputting a scene selection interface;

Optionally, the intelligent terminal may be provided with an audio sampling rate setting interface, the audio sampling rate setting interface may be provided with a scene selection function, and when receiving a first preset operation, the scene selection interface corresponding to the scene selection function is output. The first preset operation can be set according to the actual situation, and includes but is not limited to detecting a preset gesture or gesture operation, detecting a preset voice instruction, operating a preset function key, and the like. Optionally, the preset gesture may be an air gesture or the like; the preset gesture operation comprises but is not limited to preset track sliding, double clicking, single clicking, long pressing and the like; the preset voice instruction can be a scene selection voice instruction and the like; the preset function key can be a scene selection key, a scene setting key and the like.

Optionally, the scene selection interface may provide a plurality of scenes for a user to select, and the provided scenes may be displayed in the form of application type names, scene names, and the like, and when the user selects different application type names or scene names, the corresponding determined or generated scene information may be different. Referring to fig. 4, after the user clicks the scene setting button shown in (a) of fig. 4, the intelligent terminal may output a scene selection interface including a plurality of application type names, such as games, music, and the like, and if the user clicks the game type name, the intelligent terminal may correspondingly obtain low-latency required scene information; if the user clicks the music type name, the intelligent terminal correspondingly obtains high-quality audio demand scene information and the like. Therefore, the user experience is further improved by providing a scene selection interface for the user to select the corresponding scene according to the requirement.

Step S2: and determining or generating audio sampling rates of the intelligent terminal and the opposite terminal equipment to the audio data according to the scene information.

Optionally, for different scenes, the audio sampling rates of the audio data by the intelligent terminal and the peer device are required to be different, for example, for a scene with a low delay requirement, a scene in which the user experience is obviously affected by a large delay, such as a scene of playing games, the audio sampling rate of the audio data may be required to be reduced, so that the sound quality is sacrificed and the delay is improved; for high-quality demand scenes, optionally, scenes in which poor audio quality will significantly affect user experience, such as music playing, video playing, and the like, it may be required to increase the audio sampling rate of audio data as much as possible, so that partial time delay is sacrificed to replace the improvement of audio quality. Therefore, according to different scenes, the audio sampling rates of the audio data by the intelligent terminal and the opposite-end device need to be intelligently determined or generated, so that the bandwidth is fully utilized, and a user can obtain better experience. Alternatively, the audio sampling rate for the audio data may be an audio encoding sampling rate for the audio data, and may also be an audio decoding sampling rate for the audio data.

Optionally, the step S2 includes:

and sending the target audio sampling rate to the opposite terminal equipment so as to adjust the audio sampling rate of the opposite terminal equipment to the audio data to be the target audio sampling rate.

Optionally, when audio data is transmitted between the intelligent terminal and the peer device, it is generally required that the audio sampling rate of the intelligent terminal for the audio data is the same as the audio sampling rate of the peer device for the audio data. After a target audio sampling rate is determined or generated according to the scene information, the current audio sampling rate of the intelligent terminal for the audio data is adjusted to the target audio sampling rate, and the target audio sampling rate needs to be sent to the opposite terminal device, so that the audio sampling rate of the opposite terminal device for the audio data is adjusted to the target audio sampling rate, and therefore the audio sampling rate of the intelligent terminal for the audio data is ensured to be the same as the audio sampling rate of the opposite terminal device for the audio data. Optionally, after the target audio sampling rate is determined or generated according to the scene information, the audio sampling rate of the audio data by the audio control module of the intelligent terminal may be adjusted to the target audio sampling rate, so as to determine or generate the audio sampling rate of the audio data by the intelligent terminal according to the scene information.

Optionally, the intelligent terminal may send the target audio sampling rate to the peer device by sending a control instruction including the target audio sampling rate to the peer device. Optionally, the determining or generating the target audio sampling rate according to the scene information may be that, under the condition that correspondence between different scenes and audio sampling rates is pre-stored, the audio sampling rate corresponding to the scene information is determined as the target audio sampling rate by querying the correspondence, or the obtained audio sampling rate is determined as the target audio sampling rate by increasing or decreasing the initial audio sampling rate according to a preset manner, for example, one or more preset sampling rate thresholds are increased on the basis of the initial audio sampling rate. Therefore, the audio sampling rate of the intelligent terminal and the opposite terminal device to the audio data can be quickly adjusted, and the user experience is further improved.

Optionally, since link information, such as a link rate, between the intelligent terminal and the peer device determines a frequency bandwidth of a signal that can effectively pass through a link between the intelligent terminal and the peer device, the target audio sampling rate cannot exceed the link rate between the intelligent terminal and the peer device. That is, link information between the intelligent terminal and the peer device needs to be considered when determining or generating the target audio sampling rate. Therefore, the target audio sampling rate can be automatically determined or generated according to the scene information and the link information between the intelligent terminal and the opposite terminal device, so that the determined or generated target audio sampling rate can fully utilize bandwidth resources as much as possible. Optionally, when the intelligent terminal is connected with the peer device via bluetooth, the link may be a high-level communication link.

Optionally, the first type of scene and the second type of scene may be set according to actual needs, where a bandwidth required by the first type of scene is higher than a bandwidth required by the second type of scene, for example, the first type of scene may be a high-quality audio demand scene, and the second type of scene may be a low-latency demand scene. When the scene information is the first type scene, more detailed data can be collected as far as possible by increasing the initial audio sampling rate, so that the quality of the audio data can be improved. When the scene information is the second type scene, the phenomena of blocking and the like of the audio data can be avoided by reducing the initial audio sampling rate. The initial audio sampling rate may be a default audio sampling rate, such as an audio sampling rate that has been set when the intelligent terminal leaves a factory. Optionally, the increasing the initial audio sampling rate may be directly increasing the initial audio sampling rate by one or more preset sampling rate thresholds, or may be gradually increasing a plurality of preset sampling rate thresholds based on the initial audio sampling rate. Optionally, the reducing the initial audio sampling rate may be directly reducing the initial audio sampling rate by one or more preset sampling rate thresholds, or may be gradually reducing a plurality of preset sampling rate thresholds on the basis of the initial audio sampling rate. Therefore, the audio sampling rate is correspondingly adjusted according to different scene types, and bandwidth resources are further fully utilized.

and determining a target audio sampling rate corresponding to the scene information according to the corresponding relation between the scene type and the audio sampling rate in the scene information.

Optionally, the intelligent terminal may preset corresponding relationships between different scene types and audio sampling rates, and after the scene information is obtained, the audio sampling rate corresponding to the scene type in the scene information may be obtained by querying the corresponding relationships between the different scene types and the audio sampling rates, and the audio sampling rate corresponding to the scene type in the scene information is used as the target audio sampling rate corresponding to the scene information. So, can realize acquireing intelligent terminal and opposite terminal equipment fast to the audio frequency sampling rate of audio data, the simple operation has further promoted user experience.

In summary, in the control method provided by the embodiment, the audio sampling rate of the audio data by the intelligent terminal and/or the peer device is intelligently adjusted according to the scene requirements, so that bandwidth resources are fully utilized, and user experience is improved.

Optionally, before the step S1, the method further includes:

acquiring preset information of the opposite terminal equipment;

Optionally, the intelligent terminal and the peer device may have a bluetooth communication module respectively, and the intelligent terminal may perform bluetooth scanning on the peer device to obtain preset information replied by the peer device, where the preset information may be set according to actual needs, and specifically may be whether to support or not support a custom audio sampling rate function, that is, support or not support information such as a custom encoding and decoding function, and may also specifically be whether to support or not support identification information of the custom audio sampling rate function. When the intelligent terminal acquires the preset information, whether the opposite terminal equipment supports the user-defined audio sampling rate function or not can be judged according to the preset information, and if the opposite terminal equipment is determined to support the user-defined audio sampling rate function, the step S1 can be executed; if it is determined that the peer device does not support the custom audio sampling rate function, the processing may be performed according to an existing audio processing method, which is not described herein again.

Optionally, the intelligent terminal may be provided with a sampling controller, and the intelligent terminal and the peer device may be provided with a private codec and a general codec, respectively. The intelligent terminal can scan the opposite terminal device to obtain the tagged information replied by the opposite terminal device, the tagged information can be used for identifying whether the user-defined audio sampling rate function and the Bluetooth connection information are supported, and the intelligent terminal can establish Bluetooth connection with the opposite terminal device according to the tagged information. When the opposite-end equipment is determined to support the function of self-defined audio sampling rate, the proper audio sampling rate can be calculated according to the effective bandwidth, the scene information and the like between the intelligent terminal and the opposite-end equipment, and the audio sampling rate is sent to a private Codec controller of the local end so as to set the audio sampling rate as the coding sampling rate. And simultaneously sending the audio sampling rate to a private Codec controller of the opposite terminal equipment to set the audio sampling rate as a decoding sampling rate, so as to realize the synchronization of the sampling rate and the decoding rate. Therefore, when the fact that the opposite-end equipment supports the function of the user-defined audio sampling rate is determined, the audio sampling rate of the intelligent terminal and the opposite-end equipment to the audio data is determined or generated according to the scene information, and the operation effectiveness of adjusting the audio sampling rate is guaranteed.

Optionally, the method further comprises:

Optionally, the intelligent terminal may be provided with an audio sampling rate setting interface, and the audio sampling rate setting interface may be provided with an automatic audio sampling rate adjusting button and a manual audio sampling rate adjusting button, that is, an automatic mode and a manual mode for adjusting the audio sampling rate. And after receiving a second preset operation that the user needs to manually adjust the audio sampling rate, if the user clicks a button for manually adjusting the audio sampling rate, the intelligent terminal can output an audio sampling rate adjustment interface for manually adjusting the audio sampling rate by the user. Optionally, the audio sampling rate adjustment interface may be provided with a slider or a slider for adjusting the audio sampling rate, and a user may input an operation instruction to the intelligent terminal by dragging the slider or the slider, so as to adjust the audio sampling rate. Referring to fig. 5, after the user clicks the manual mode button shown in (a) of fig. 5, the user may adjust the audio sampling rate slider shown in (b) of fig. 5 as needed. Therefore, the user experience is further improved by providing an audio sampling rate adjusting interface for the user to select manual adjustment of the audio sampling rate according to the requirement.

Based on the same inventive concept of the foregoing embodiment, the foregoing embodiment is specifically described below by using a specific example, in this embodiment, the intelligent terminal is represented as Source, the peer device is represented as Sink, and the audio sampling rate includes an encoding sampling rate and a decoding sampling rate.

Referring to fig. 6, an audio processing method provided in the embodiment of the present application mainly includes:

1) and in the scanning discovery stage, the Source scans the Sink through the Bluetooth communication module, and the Sink replies tagged information to the Source.

2) In the connection stage, establishing Bluetooth connection with Sink by Source according to tagged information replied by the Sink, verifying whether the Sink supports a user-defined coding and decoding function according to the tagged information, and coding and decoding through a private coder-decoder (Codec) if the Sink supports the user-defined coding and decoding function; if not, the coding and decoding are carried out by a general coder decoder (Codec).

3) The Source terminal can be provided with a sampling controller and provides two modes: the system comprises an automatic mode and a manual mode, wherein the automatic mode is to automatically calculate a proper sampling rate through bandwidth and scenes, and the manual mode is to support a user to manually self-define and adjust the sampling rate and select the sampling rate corresponding to a preset scene.

4) The Source terminal can provide an automatic and manual mode switching entrance, when the user selects the automatic mode, a corresponding instruction is issued to the local controller, namely the sampling controller, the sampling controller calculates a proper sampling rate according to the information of effective bandwidth, scene and the like, and sends the sampling rate to the private Codec controller of the Source terminal so as to set the sampling rate as the coding sampling rate. And meanwhile, the sampling rate is sent to a private Codec controller of the Sink to set the sampling rate as a decoding sampling rate, so that the synchronization of the sampling rate and the decoding rate is realized. When the user selects the manual mode, the user can select locally stored sampling rates which are configured for different scenes and defaults, and after the user selects a scene, the Source end directly issues the sampling rate corresponding to the scene to the local private Codec controller and synchronizes the sampling rate to the Sink private Codec controller. Optionally, the user may also customize the sampling rate, and issue the customized sampling rate to the local private Codec controller and synchronize the customized sampling rate to the private Codec controller of the Sink.

5) The step of setting the sampling rate by the sampling controller includes not only the initial stage of establishing the connection, but also dynamic adjustment during the service scene (e.g. listening to songs, playing games, etc.).

In summary, in the audio processing method provided in the embodiment of the present application, the theoretical bandwidth is fully utilized by dynamically adapting the current theoretical rate, and the problem that the performance is wasted due to audio compression when the bluetooth theoretical bandwidth is high and the audio data transmission requirement is greater than the available bandwidth when the bluetooth theoretical bandwidth is low in a complex interference scenario, which results in audio jamming, is solved in that the fixed sampling rate is adopted for encoding and decoding; in addition, by adding the user entrance, the user can manually adjust the sampling rate according to the scene requirement, and the problems that the sampling rate cannot be automatically adapted to the scene during the traditional coding and decoding, the user cannot intervene, the high-quality audio cannot be exchanged by sacrificing part of time delay when the requirement on the audio quality is high, and the time delay is improved by sacrificing the tone quality under the high-time delay scene such as games are solved.
