With the above figures, there are shown specific embodiments of the present application, which will be described in more detail below. The drawings and written description are not intended to limit the scope of the inventive concepts in any manner, but rather to illustrate the concepts of the application by those skilled in the art with reference to specific embodiments.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

Referring to fig. 1, fig. 1 is a schematic view illustrating an application scenario of a method for calling microphone resources according to the present application.

As shown in fig. 1, a plurality of services may be set in the terminal device 101, and one service may be one Application (APP). That is, a plurality of applications can be downloaded and run in the terminal apparatus 101.

The terminal apparatus 101 may be a wireless terminal or a wired terminal. A wireless terminal may refer to a device that provides voice and/or other traffic data connectivity to a user, a handheld device having wireless connection capability, or other processing device connected to a wireless modem. A wireless terminal, which may be a mobile terminal such as a mobile telephone (or "cellular" telephone) and a computer having a mobile terminal, for example, a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device, may communicate with one or more core Network devices via a Radio Access Network (RAN), and may exchange language and/or data with the RAN. For another example, the Wireless terminal may also be a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), and other devices. A wireless Terminal may also be referred to as a system, a Subscriber Unit (Subscriber Unit), a Subscriber Station (Subscriber Station), a Mobile Station (Mobile), a Remote Station (Remote Station), a Remote Terminal (Remote Terminal), an Access Terminal (Access Terminal), a User Terminal (User Terminal), a User Agent (User Agent), and a User Equipment (User Device or User Equipment), which are not limited herein. Optionally, the terminal device may also be a smart watch, a tablet computer, or the like.

Illustratively, as shown in fig. 1, the terminal apparatus 101 may include an application a and an application B therein.

The terminal device 101 may also be provided with at least one microphone, e.g. the terminal device 101 may be provided with one microphone, or the terminal device 101 may be provided with two microphones, etc.

The location of the microphone on the terminal device 101 is not limited in this embodiment.

In one example, if the number of the microphones is one, the microphones may be disposed at a position above the screen of the terminal device 101, such as the microphones may be disposed at a position flush with the camera, or the microphones may be disposed at a position below the screen, such as the microphones may be disposed at a position flush with the charging interface, or the microphones may be disposed at a left side of the terminal device 101, or the microphones may be disposed at a right side of the terminal device 101, etc., which are not listed again.

In another example, if the number of the microphones is multiple, any one of the multiple microphones may be set by referring to the position of the microphone, which is not described herein again.

As shown in fig. 1, the user 102 may start multiple applications in the terminal device 101 at the same time, and the multiple applications may need to use the microphone resource at the same time, for example, the multiple applications need to acquire corresponding audio data through the recording function of the microphone.

For example, taking application a and application B shown in fig. 1 as an example, the following is exemplarily described:

both application a and application B need to use the microphone resource, and if both need to obtain corresponding audio data through the recording function of the microphone.

However, in the related art, the audio resource management policy of the android Operating System (OS) platform does not support multiple recording tracks (tracks) nor does it support concurrent voice and recording, so if the application a is recording or talking on a microphone, the application B cannot use the microphone, and needs to wait for the application a to record or finish the voice call, and release the microphone resource, then the application can use the microphone.

Therefore, the method for calling the microphone resource in the related art cannot simultaneously satisfy the requirements of multiple services (i.e., multiple applications), which results in a problem of low resource utilization rate and low flexibility of microphone utilization.

In order to solve at least one of the above technical problems, the inventors of the present application have made creative efforts to obtain the inventive concept of the present application: if the microphone resource is already used by the service, the audio data acquired based on the microphone resource can be copied, and the copied audio data is sent to the service requesting to use the microphone.

The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. These several specific embodiments may be combined with each other below, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 2 is a flowchart illustrating a method for calling a microphone resource according to an embodiment of the present application.

As shown in fig. 2, the method includes:

s201: and receiving a first sound recording request initiated by a first service.

The method of the embodiment may be applied to a terminal device, where the terminal device is provided with multiple services, each service may use a microphone resource of the terminal device through a recording request, and the first recording request is used to instruct recording based on the microphone resource.

For example, the execution main body of this embodiment may be a calling device of a microphone resource (hereinafter, referred to as a calling device for short), and the calling device may be a terminal device, an electronic device, a server, a processor, a chip, or the like, and this embodiment is not limited thereto.

For example, if the calling device is a terminal device, the description of the terminal device may refer to the description of the terminal device in the application scenario, and is not described herein again.

For another example, if the calling device is an electronic device, the electronic device may be a recorder, and the recorder has a voice recording service and a communication (e.g., a talk-over call) service.

That is to say, the method for calling the microphone resource according to the embodiment may be applied to the application scenario shown in fig. 1, and may also be applied to an application scenario of security protection, for example, in the process of security protection, relevant staff may obtain evidence through a recorder, for example, by recording sound, so as to obtain corresponding evidence, and contact and communication with other relevant staff may also be achieved through the recorder.

It should be understood that the above examples are only used for exemplary illustration, and the calling method of the microphone resource of the present embodiment may be applied to an application scenario, and is not to be construed as a limitation to the application scenario.

S202: and if the terminal equipment is in the state of providing the microphone resources for the second service, copying the audio data acquired by providing the microphone resources for the second service to obtain copied audio data.

S203: and feeding back the copied audio data to the first service.

Exemplarily, taking the first service as a voice recording service and the second service as an intercom service as an example, the present embodiment is exemplarily described as follows:

after receiving the voice recording service, the calling device judges whether the microphone resource is used by other services, if the calling device determines that the microphone resource is used by the talkback service, the audio data obtained by providing the microphone resource for the talkback service is copied to obtain copied audio data, and the copied audio data is sent to the talkback service.

That is to say, in this embodiment, the copied audio data can be obtained by copying the audio data, and by sending the copied audio data to the talkback service, the implementation of the voice recording service and the implementation of the talkback service are both satisfied, so that the microphone resources are shared by different services, the resource utilization rate is improved, and the technical effects of diversity and flexibility of the application of the microphone are improved.

Based on the above analysis, an embodiment of the present application provides a method for calling a microphone resource, which is applied to a terminal device, where the terminal device is provided with multiple services, and each service can use the microphone resource of the terminal device through a recording request, and the method includes: receiving a first recording request initiated by a first service, wherein the first recording request is used for indicating recording based on microphone resources, and if a terminal device is in a state of providing the microphone resources for a second service, copying audio data obtained by providing the microphone resources for the second service to obtain copied audio data, and feeding the copied audio data back to the first service, in this embodiment, when the microphone resources are already used, the audio data obtained based on the microphone resources can be copied to obtain copied audio data, so that the copied audio data can be fed back to the service initiating the recording request later, thereby realizing that multiple services commonly use the microphone resources, i.e. realizing concurrence of recording requirements on microphones, improving resource utilization rate, and satisfying requirements of users on microphone resources, the technical effect of the user experience is increased.

Fig. 3 is a flowchart illustrating a method for calling microphone resources according to another embodiment of the present application.

As shown in fig. 3, the method includes:

s301: and receiving a first sound recording request initiated by a first service.

For example, the description about S301 may refer to S201, and is not described herein again.

S302: and judging whether the microphone resources are used by other services, if so, executing S303, and if not, executing S310.

S303: and copying the audio data acquired by providing microphone resources for other services to obtain copied audio data.

For example, if the invoking device determines that the microphone resource is already used by the other service, and in combination with the above embodiment, if the other service is the second service, that is, the microphone resource is used by the second service, the invoking device may copy the audio data acquired and provided for the second service, to obtain the copied audio data.

Specifically, if the number of the first services is one, one copy of audio data may be copied, and if the number of the first services is multiple, multiple copies of audio data may be copied, that is, the calling device may determine the number of copies of audio data based on the number of the first services, so as to subsequently allocate one copy of audio data to each first service.

S304: and according to the recording parameter of the first service, resampling the copied audio data to obtain resampled data.

Wherein, the first recording request carries the recording parameter. The recording parameters may be set by the calling device based on the requirements of the service for recording. That is, different services have different recording requirements, and the different recording requirements correspond to different recording parameters. The recording parameters may characterize parameters related to the quality of the audio data, etc.

It should be noted that, in this embodiment, the audio data after being copied is resampled by combining the recording parameter of the first service, so that the obtained resampled data meets the requirement of the first service, and different audio data can be allocated to different services, thereby achieving diversity and flexibility, and enabling the resampled data received by each service not to be interfered by other data, and meeting the technical effect of user experience.

S305: and feeding back the resample data to the first service according to the identifier of the first service.

Wherein, the first recording request carries the identifier of the first service.

For example, different services have different identifiers, when each service sends a first recording request to the calling device, the identifier of each service may be carried in the first recording request, and after the calling device obtains resampled data, the calling device may allocate corresponding resampled data to each service based on the identifier of each service.

It should be noted that, in this embodiment, the resample data is fed back to the first service through the identifier of the first service, so that the technical effects of accuracy and reliability of the feedback of the resample data can be improved.

S306: and receiving a second sound recording request initiated by the first service.

Wherein the second recording request is used for indicating to stop recording.

S307: and judging whether the terminal equipment needs to provide microphone resources for other services, if so, executing S308, and if not, executing S309.

S308: and stopping copying the audio data for the first service according to the second recording request.

For example, with reference to the foregoing embodiment, if the calling device provides audio data for the first service and the second service respectively, and if the first service requests stopping recording, the calling device may stop copying the audio data for the first service, that is, the calling device does not need to copy the audio data any more, and does not need to feed the copied audio data back to the first service, but only needs to provide the audio data for the second service.

It should be noted that, in this embodiment, when a certain service requests stopping recording, the calling device may stop copying audio data for the service without affecting the provision of audio data for other services, and therefore, the technical effects of providing flexibility, diversity and reliability of audio data may be achieved.

S309: and stopping recording according to the second recording request and releasing the microphone resource.

For example, in this embodiment, if the calling device does not need to provide audio data for any service task any more, the calling device may stop recording based on the second recording request and release the microphone resource, thereby achieving the technical effects of reducing the load and improving the resource utilization rate.

S310: an Audio Record instance is implemented by creating a sound Record according to the first sound Record request.

In some embodiments, the first recording request may carry attribute information of the first service, where the attribute information may be understood as related information representing an identity or an authority of the first service, the invoking device may verify the authority of the first service based on the attribute information of the first service, if the verification passes, the invoking device may create an Audio Record instance according to the first recording request, and if the verification fails, the invoking device may feed back prompt information to the first service, so as to prompt that the first service does not have an authority to use a microphone resource, and the like.

S311: and acquiring Audio data collected based on a microphone according to the Audio Record example, and feeding back the Audio data to the first service.

That is to say, in this embodiment, the calling device may obtain the Audio data by creating an Audio Record instance, and since no other service uses the microphone resource, the calling device may directly feed back the obtained Audio data to the first service.

It should be noted that, by acquiring and feeding back Audio data in a manner of creating an Audio Record instance, the technical effect of flexibility and diversity of feeding back Audio data can be achieved.

The computer system may include clients and servers. A client and server are generally remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other.

According to another aspect of the embodiment of the present application, a terminal device is also provided in the embodiment of the present application.

Referring to fig. 7, fig. 7 is a schematic diagram of a terminal device according to an embodiment of the disclosure.

As shown in fig. 7, the terminal device 700 includes: an android operating system platform 701, a microphone resource multiplexing virtual layer 702, and an application program interface 703, wherein,

the application program interface 703 is configured to receive a first recording request initiated by the first service, where the first recording request is used to instruct recording based on the microphone resource.

In some embodiments, the application program interface 703 may include a virtual microphone control interface and a virtual microphone recording interface.

The virtual microphone recording interface may receive a first recording request initiated by a first service, that is, the virtual microphone recording interface may interact with the service, so as to receive the first recording request sent by any service, and a second recording request for instructing to stop recording.

The virtual microphone control interface may be used to switch different microphones. For example, if two microphones are provided on the terminal device, the virtual microphone control interface may be switched from one of the microphones to the other microphone.

With reference to the foregoing embodiment, it can be known that the first recording request may carry the recording parameter, the identifier, the attribute information, and the like of the first service, and accordingly, the virtual mike recording interface may obtain and record the recording parameter, the identifier, the attribute information, and the like of the first service carried in the first recording request.

And the microphone resource multiplexing virtual layer 702 is configured to, if the terminal device is in a state of providing microphone resources for the second service, copy the audio data acquired by providing the microphone resources for the second service to obtain copied audio data.

Wherein the audio data is acquired from the android operating system platform 701.

In some embodiments, the microphone resource multiplexing virtual layer 702 may include a service registration management unit, a basic configuration management unit, a recording policy management unit, a data cache management unit, and a resampling unit.

The virtual microphone recording interface can send the recording parameters to the service registration management unit.

The service registration management unit acquires the recording parameter of the first service (the recording parameter is stored when the first service is registered for the first time) from the basic configuration management unit, and if the recording parameter provided by the virtual microphone recording interface is the same as the recording parameter stored in the basic configuration management unit, the service registration management unit applies for creating an Audio Record instance from the recording strategy management unit.

The recording strategy management unit creates an Audio Record instance, acquires Audio data from an android operating system platform according to the Audio Record instance, and stores the Audio data to the data cache management unit.

And if the first service and the second service both need to use the microphone resource, the recording strategy management unit copies the audio data in the data cache management unit.

And the resampling unit is used for resampling the copied audio data based on the recording parameter of the first service to obtain resampled data, and sending the resampled data to the application program interface, and the application program interface is used for sending the resampled data to the first service.

The recording strategy management unit can also be used for releasing the resources of the microphone and the android operating system platform.

The application program interface 701 is configured to feed back the copied audio data to the first service.
