[0059] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0060] The embodiment of the present invention provides a method for collecting audio data, such as Figure 1 As shown, the method includes:

[0061] 101. In response to a startup instruction of an application program, detect whether the virtual audio driver has been installed.

[0062] In an embodiment of the present invention, the current execution end, as the execution end of the application program for executing the audio data acquisition method, can be a terminal device, such as a mobile phone terminal, a tablet terminal or a computer terminal, which is not specifically limited in the embodiment of the present invention. Among them, the virtual audio driver is a virtual audio driver program, which is used to allow an application (such as a speaker) to pass audio to other applications (output devices), including but not limited to blackhodle, soundflower iShowU AudioCapture and other virtual audio drivers, which are not specifically limited in the embodiment of the present invention. The user first installs the application on the terminal device and triggers the startup instruction of the application program, so that after the current execution end responds to the startup instruction of the application program, it detects whether the virtual audio driver has been installed, so as to determine that after the installation is completed, the step of creating the output device is executed using the installed virtual device.

[0063] It should be noted that the driver in the embodiment of the present invention refers to a software program that drives the computer hardware to run. In this case, the driver is a device driver, which is a special program added to the operating system, which contains information about the hardware device. This information enables the computer to communicate with the corresponding device.

[0064] 102. If the virtual audio driver is installed, call a multi-output device created in the target system based on the virtual audio driver.

[0065] In the embodiment of the present invention, after the current execution end installs the virtual audio driver, a multi-output device is created through the virtual device obtained by installing the virtual audio driver. At this time, the installation process of the virtual audio driver can be before step 101, or it can be installed in real time after detecting that the virtual audio driver is not installed, so that it can be called by the application after completion. Among them, the multi-output device is used to represent the device that plays audio data in the terminal system, including but not limited to speakers, sound cards, Bluetooth headsets, etc., which are not specifically limited in the embodiment of the present invention.

[0066] It should be noted that when a multi-output device is created in a target system based on a virtual audio driver, the target system is an operating system of the current terminal device, such as a max osx system, and the embodiment of the present invention does not make any specific limitation.

[0067] 103. When an audio collection instruction is obtained through the application, the selected collection object is configured as the multi-output device, and audio data is collected from the collection object through the multi-output device.

[0068] In an embodiment of the present invention, when a user needs to record audio data in a target system, the user selects the acquisition object to be recorded through the application program, and triggers the audio acquisition instruction. The current execution end configures the acquisition object with the created multi-output device through the application program, thereby performing audio data acquisition through the created multi-output device. At the same time, the current execution end also sets a callback function. After the acquisition is performed through the multi-output device, the collected audio data will be called back to the set callback function so that it can be retrieved in the application program at any time. When configuring the acquisition object as a multi-output device, specifically, the virtual device output device of the multi-output device is set to the real output device speaker of the system through CFDictionaryAddValue. Finally, the ID of the created multi-output virtual device is obtained through AudioDeviceGetProperty, and the device is set to the system default output device through AudioHardwareSetProperty., thereby realizing the synchronous recording of audio data based on multi-output devices.

[0069] In another embodiment of the present invention, for further definition and description, the method further includes:

[0070] When the multi-output device is not retrieved, running the virtual audio driver in the application;

[0071] The application programming interface of the target system is called, and the multi-output device is created based on the application programming interface.

[0072] In order to meet the purpose of multi-channel output of audio data to achieve the purpose of parallel collection of audio data and realize the purpose of unmanned audio recording, when the current execution end calls the multi-output device, if the current execution end does not detect the created multi-output device, it means that the multi-output device has not been created. Therefore, the virtual audio driver is called to run, and the application programming interface of the target system is called through the application, such as the compilation interface executeAndReturnError to run the driver, and then the system API is called, such as the AudioDeviceGetProperty compilation interface. At the same time, this AudioDeviceGetProperty is called to obtain the speaker device ID to be created. Through the system API, such as the AudioHardwareCreateAggregateDevice compilation interface, the speaker ID as the collection object and the virtual device ID of the running driver are associated, thereby creating a virtual device with multiple output devices, which is not specifically limited in the embodiment of the present invention.

[0073] In a specific implementation scenario, the method further includes:

[0074] The multiple output device is configured as a default output device.

[0075] In order to meet the requirement of synchronous audio recording when the speaker plays audio data in the target system and avoid the tediousness of manual operation, the current execution end configures the multi-output device as the default output device after creating the multi-output device, such as obtaining the created multi-output virtual device ID through the AudioDeviceGetProperty compilation interface, and then setting the multi-output device as the system default output device through the AudioHardwareSetProperty compilation interface, so that the audio data generated by the speaker can be collected in real time.

[0076] It should be noted that the API in the embodiment of the present invention is an application programming interface (Application Programming Interface), which is a predefined function. Its purpose is to provide applications and developers with the ability to access a set of routines based on certain software or hardware without having to access the source code or understand the internal working mechanism.

[0077] In another embodiment of the present invention, for further definition and explanation, before the step of detecting whether the virtual audio driver has been installed, the method further includes:

[0078] Retrieve the execution script of the application and insert the downloaded driver file into the execution script;

[0079] Running the execution script through the execution interface of the target system to complete the installation of the virtual audio driver;

[0080] After detecting whether the virtual audio driver has been installed, the method further includes:

[0081] If the virtual audio driver has not been installed, the execution script is retrieved and run through the execution interface of the target system to install the virtual audio driver.

[0082] In order to realize the automatic installation of the virtual audio driver, the application automatically calls the execution script and inserts the driver file of the virtual audio driver downloaded in advance into the execution script, so that the virtual audio driver can be automatically run when the application is executed. In the embodiment of the present invention, when installing the virtual audio driver, the application runs the execution script through the execution interface of the target system, thereby automatically completing the installation of the virtual audio driver. For example, the script is run through the API of the target system (such as executeAndReturnError) to install it. Figure 2 In the process of installing a driver and creating a multi-output device shown, the virtual audio driver may be a blackhodle driver, which is not specifically limited in the embodiment of the present invention.

[0083] In another embodiment of the present invention, for further definition and explanation, before the step responds to the startup instruction of the application program and detects whether the virtual audio driver has been installed, the method further includes:

[0084] In response to a download instruction of the application, download a driver file of the virtual audio driver so as to retrieve the driver file for installation; or,

[0085] When it is detected that the installation of the virtual audio driver fails, the step of downloading the driver file of the virtual audio driver is re-executed to re-download and install it.

[0086] In order to effectively execute the audio data collection, the current execution end also detects in real time whether there is a virtual audio driver that has been downloaded but not installed in the current execution end, that is, in response to the download instruction of the application, the driver file of the virtual audio driver is downloaded so that the driver file is retrieved for installation, such as Figure 2 When downloading the driver file of the virtual audio driver, a virtual audio driver loading request can be sent to the server connected to the application program to download the driver file of the virtual audio driver, so that the driver file of the virtual audio driver is retrieved for automatic installation. When it is detected that the installation of the virtual audio driver fails, the step of downloading the driver file of the virtual audio driver can be re-executed to re-download and install.

[0087] In another embodiment of the present invention, for further definition and explanation, before the step of configuring the selected acquisition object as the multi-output device, the method further includes:

[0088] All acquisition objects in the target system are acquired and output through the application program for selection of the acquisition objects.

[0089] In order to meet the user's purposeful recording needs for audio data, thereby improving the effectiveness of audio data collection, all collection objects in the target application are obtained through the application. At this time, the collection object is the object in the target system that needs to record audio data, such as a player port, a video port, etc., which is not specifically limited in the embodiment of the present invention. Furthermore, all collection objects are output in the application, and the user can select the collection object that needs to be recorded to trigger the audio collection instruction for the selected collection object in the application. The embodiment of the present invention does not specifically limit the output form of the collection object.

[0090] In another embodiment of the present invention, for further definition and explanation, after the step of calling the multiple output devices created in the target system based on the virtual audio driver, the method further includes:

[0091] When an audio collection instruction is obtained through a third-party application, configuring a collection object selected in the third-party application as the multi-output device;

[0092] Audio data is collected from the collection object through the multi-output device.

[0093] In order to meet the diverse needs of applications for automatic audio recording, users can also enter collection objects that need to collect audio data through third-party applications. Therefore, the collection objects selected in the third-party applications are configured as multi-output devices to collect audio data for the collection objects through the multi-output devices.

[0094] It should be noted that the application in the embodiment of the present invention can be an application developed by the user, that is, the multi-output device configuration is included in the business execution file during the application development process, and there is no need to call the speaker step. The third-party application can be all applications other than self-developed applications, and the embodiment of the present invention does not make specific limitations. In addition, for different applications in the current execution end, the generated audio files can be stored in the download file corresponding to the application so that the user can call it in real time, which is not specifically limited in the embodiment of the present invention.

[0095] In another embodiment of the present invention, for further definition and description, the steps further include:

[0096] Obtaining basic audio parameters and audio collection requirements of the target system;

[0097] The basic audio parameters are adjusted based on the audio collection requirements, and the multi-output device is configured according to the adjusted audio parameters to collect the audio data according to the audio parameters.

[0098] In order to meet the needs of flexible recording, the current execution end can also automatically configure the audio data played by the speaker and the audio effects recorded. Specifically, first obtain the basic audio parameters of the target system and the audio collection requirements for recording audio data, so as to configure multiple output devices according to the adjusted audio parameters, thereby collecting audio data according to the audio parameters. Among them, the basic audio parameters include volume parameters and mute parameters, and the audio collection requirements include target audio size and target mute state. At this time, the volume parameters and mute parameters in the basic audio parameters are adjusted according to the target audio size and target mute state in the audio collection requirements. For example, call the AudioObjectSetPropertyData compilation interface to adjust the volume of the speaker to the maximum, unmute, and ensure that the recorded sound is maximized, thereby achieving the purpose of flexible collection of audio data.
