[0053] Fig. 1 is a block diagram of a hardware configuration of an electronic device for implementing a recording method according to an embodiment of the present application. The electronic device 1000 is exemplarily a head-mounted display device (such as AR, MR, VR, etc. XR glasses, a helmet, etc.), a smartphone, a notebook computer, a tablet computer, etc.

[0054] The electronic device 1000 can include a processor 1100, a memory 1200, an interface unit 1300, a communication unit 1400, a display unit 1500, an input unit 1600, a speaker 1700, a microphone 1800, etc. The processor 1100 can be a central processing unit (CPU), a micro processing unit (MCU), etc. The memory 1200 can include, for example, a ROM (read only memory), a RAM (random access memory), a nonvolatile memory such as a hard disk, etc. The interface unit 1300 can include, for example, a USB interface, a headphone interface, etc. The communication unit 1400 can perform wired or wireless communication, for example. The display unit 1500 can be, for example, a liquid crystal display, a touch display, etc. The input unit 1600 can include, for example, a touch screen, a key, etc. A user can input / output voice information through the speaker 1700 and the microphone 1800.

[0055] Although the electronic device 1000 is shown as including a plurality of units in Fig. 1, the present application can relate to only a part of the units, for example, the electronic device 1000 can relate to only the memory 1200 and the processor 1100.

[0056] The memory 1200 of the electronic device 1000 according to an embodiment of the present application can store instructions for controlling the processor 1100 to perform a recording method according to an embodiment of the present application.

[0057] In the above description, a skilled person can design the instructions according to the disclosed scheme. How the instructions control the processor to operate is known in the art, and thus will not be described in detail herein.

[0058] In the conventional technology, in a case where an application A sends a recording request to an electronic device, the electronic device only applies for a storage space and turns on a microphone. Further, after storing an audio signal a for a voice input to the application A, which is collected by the microphone, to the storage space, the application A directly reads the audio signal a from the storage space. This makes other applications B fail to send a recording request to the electronic device, and audio signals b for voices input by a user to the other applications B are all stored in the storage space applied for by the electronic device for the application A, and are further read by the application A. That is, in the conventional technology, the other applications B cannot read the audio signals b for the voices input by the user to the other applications B.

[0059] To solve the above problems, the application provides a recording method as shown in FIG. 2, which comprises the following steps S2100 to S2400.

[0060] Step S2100, in the case of receiving a recording request sent by at least one application, applying for a storage space and starting a microphone.

[0061] In the embodiment, the application in step S2100 can be an application running in an electronic device for executing the recording method provided by the application, and can also be an application running in a terminal device connected with the electronic device. For the latter, the electronic device is, for example, an XR glasses, and the application is an application running in a smart phone connected with the XR glasses and displayed in a virtual space created by the XR glasses. In this regard, in an embodiment of the application, the method provided by the application further comprises the following steps S2110 and S2111 before step S2100.

[0062] Step S2110, for at least one application, receiving the current display image data of the application sent by the terminal device connected in communication.

[0063] Step S2111, according to the display position corresponding to the terminal device, displaying the current display image data at the display position.

[0064] In the embodiment, the display screen of the electronic device is planned as a plurality of display positions, and one display position corresponds to one terminal device connected with the electronic device. After receiving the current display image data of the application sent by one terminal device, the current display image data is displayed at the display position corresponding to the terminal device. In this way, the user can view the current display image data corresponding to the application on the electronic device, thereby providing a basis for the user to provide voice input.

[0065] Further, it can be understood that at the same time, the user using the electronic device for executing the recording method provided by the application can only speak the voice for one application. Therefore, in the embodiment, there is only one application sending a recording request to the electronic device at the same time. That is, the recording request in step S2100 is received by the electronic device at different times. For any recording request, the recording request can include sampling rate, channel number, bit number, application identifier, etc.

[0066] For the step S2100, in the case that the recording request sent by at least one application is received, it is indicated that there is a recording demand. At this time, the microphone is turned on, and the audio signal collected by the microphone is stored in a first storage space.

[0067] In an embodiment of the present application, the size of the first storage space can be specifically a preset bit number.

[0068] For the step S2200, for any recording request sent by an application, a second storage space corresponding to the application is applied.

[0069] In the embodiment, in the case that a recording request sent by an application is received, a second storage space corresponding to the application sending the recording request is applied. The second storage space is used to store the sub-audio signal of the user for the application corresponding to the recording request.

[0070] It should be noted that in the present application, the application, the recording request and the second storage space have a one-to-one correspondence.

[0071] For the step S2300, the audio signal collected by the microphone is stored in the first storage space.

[0072] For the step S2400, the sub-audio signal of each application in the first storage space is stored in the corresponding second storage space.

[0073] In the embodiment, in the case that the microphone is turned on, the audio signal collected by the microphone is first stored in the first storage space. It can be understood that the first storage space includes the sub-audio signal of the voice of the user for the application corresponding to the different recording requests. Further, the sub-audio signal of the voice of the user for the application corresponding to the different recording requests in the first storage space is sent to the corresponding second storage space. On this basis, the application reads the sub-audio signal from the corresponding second storage space, and the sub-audio signal of the voice of the user for the application can be obtained. In this way, each application can read the audio signal of the voice of the user for the application. Therefore, based on the steps S2100 to S2400, different applications can send a recording request to the electronic device, and the electronic device can successfully respond to the recording request of different applications, so that different applications can read the corresponding sub-audio signal. This solves the problem that when multiple applications need to call the microphone on the XR head-mounted display device for recording, the first application calling the microphone will lock the microphone, and other applications cannot request to use the microphone until the first application releases the microphone, and other applications can successfully request the microphone.

[0074] For the above steps S2100 to S2400, in one example, the application A first sends a recording request 1 to the electronic device, at this time, the electronic device opens the microphone, applies a first storage space, and applies a second storage space I. During the opening of the microphone, the microphone stores the sub-audio signal a of the voice input by the user to the application A into the first storage space. Further, the application B sends a recording request 2 to the electronic device again, at this time, the electronic device applies a second storage space II, and the microphone stores the sub-audio signal b of the voice input by the user to the application B into the first storage space. Further, the electronic device stores the sub-audio signal a in the first storage space into the second storage space I, and stores the sub-audio signal b in the first storage space into the second storage space II.

[0075] The present application provides a recording method, comprising: in the case of receiving a recording request sent by at least one application, applying a first storage space and opening a microphone; for any recording request sent by an application, applying a second storage space corresponding to the application; storing the audio signal collected by the microphone into the first storage space; storing the sub-audio signal belonging to each application in the first storage space into the corresponding second storage space. Based on the method, different applications can send a recording request to the electronic device, the electronic device can successfully respond to the recording request of different applications, so that different applications can read the corresponding sub-audio signal. This solves the problem that when multiple applications need to call the microphone on the XR head-mounted display device for recording, the first application that calls the microphone will lock the microphone, other applications cannot request to use it until the first application releases the microphone, and other applications can successfully request the microphone.

[0076] In one embodiment of the present application, on the basis of the above steps S2100 to S2400, the recording method provided by the present application further comprises the following step S2500.

[0077] Step S2500, for any second storage space, sending the sub-audio signal stored in the second storage space to the corresponding application.

[0078] Based on the above step S2500, each application that sends a recording request can read the sub-audio signal of the voice input by the user.

[0079] In one embodiment of the present application, the above step S2400 is specifically implemented by the following two ways.

[0080] In the first mode, the audio recording request includes at least an audio data format required by the corresponding application. Based on this, the audio recording method further includes the following step S2210 after step S2200.

[0081] In step S2210, for any second storage space, the audio data format included in the corresponding audio recording request is stored in the second storage space.

[0082] In this embodiment, after the second storage space is applied, the audio data format included in the corresponding audio recording request is stored in the second storage space.

[0083] Based on step S2210, step S2400 is implemented through the following steps S2410 to S2412.

[0084] In step 2410, for any second storage space, the audio data format is read from the second storage space.

[0085] In this embodiment, the audio data format is stored in the second storage space. Based on this, the audio data format can be directly read from the second storage space.

[0086] In step S2411, the sub-audio signal in the first storage space belonging to the application program corresponding to the second storage space is processed according to the audio data format, and a processed sub-audio signal is obtained.

[0087] It should be noted that the processing in step S2411 specifically refers to decoding into original data and then encoding according to the read audio data format.

[0088] In step S2412, the processed sub-audio signal is sent to the corresponding second storage space.

[0089] For the steps S2410 to S2412, in one example, the first storage space stores the sub-audio signal a of the voice input by the user for the program A and the sub-audio signal b of the voice input by the user for the program B, and the electronic device applies the second storage space I for the application program A and the second storage space II for the application program B, the second storage space I stores the audio data format one, and the second storage space II stores the audio data format two. On this basis, the audio data format one required by the application program A is read from the second storage space I, the sub-audio signal a in the first storage space is processed according to the audio data format one to process it into the audio signal (i.e. the processed sub-audio signal a) of the audio data format one, and then stored in the second storage space I. And the audio data format two required by the application program B is read from the second storage space II, the sub-audio signal b in the first storage space is processed according to the audio data format two to process it into the audio signal (i.e. the processed sub-audio signal b) of the audio data format two, and then stored in the second storage space II. On this basis, the application program A can read the audio signal of the data format one required by itself from the second storage space I, and the application program B can read the audio signal of the data format two required by itself from the second storage space II. At this time, the application program A and the application program B do not need to process the audio signal.

[0090] In the embodiment, based on the steps S2410 to S2412, the sub-audio signal of the audio data format required by the corresponding application program can be stored in the second storage space. In this way, the application program can directly read and use without processing the audio signal.

[0091] For the second mode, the recording request at least includes the audio data format required by the corresponding application program, and the recording method provided by the embodiment of the application further includes the following step S2220 after the step S2200.

[0092] In the step S2220, for the second storage space corresponding to the second recording request, the audio data format included in the second recording request is stored in the second storage space, and the second recording request is the recording request other than the first recording request in the recording request, and the first recording request is the first received recording request.

[0093] In the embodiment, the first received recording request is recorded as the first recording request, and the recording request received after the first recording request is recorded as the second recording request. And only the audio data format included in the second recording request is stored in the corresponding second storage space, and the audio data format included in the first recording request is not stored in the corresponding second storage space.

[0094] Further, the step S2300 is implemented by the following step S2310.

[0095] In the step S2310, the audio signal collected by the microphone is stored in the first storage space according to the audio data format included in the first recording request.

[0096] In the embodiment, since the data format of the audio signal in the first storage space is the audio data format included in the first recording request, it is not necessary to store the audio data format included in the first recording request in the corresponding second storage space. It is only necessary to send the sub-audio signal belonging to the application program corresponding to the first recording request in the first storage space to the corresponding second storage space, and the second storage space can obtain the sub-audio signal of the audio data format required by the application program. On this basis, the step S2400 is implemented by the following steps S2420 and S2421.

[0097] In the step S2420, for any second recording request corresponding second storage space, the audio data format is read from the second storage space, the sub-audio signal belonging to the application program corresponding to the second storage space in the first storage space is processed according to the read audio data format to obtain the processed sub-audio signal, and the processed sub-audio signal is sent to the corresponding second storage space.

[0098] In the step S2421, the sub-audio signal belonging to the application program corresponding to the first recording request in the first storage space is sent to the corresponding second storage space.

[0099] For the steps S2420 to S2421, in one example, the application A first sends the electronic device a recording request 1, at this time, the electronic device takes the recording request 1 as a first recording request, opens the microphone, applies a first storage space which can at least meet the size required by the application A according to the recording request 1, and applies a second storage space I which can meet the size required by the application A. During the opening of the microphone, the microphone collects a sub-audio signal a of the voice input by the user to the application A. The electronic device processes the sub-audio signal a according to the audio data format one in the recording request 1, and stores the processed sub-audio signal a into the first storage space. Further, the application B sends the electronic device a recording request 2 again, at this time, the electronic device takes the recording request 2 as a second recording request, and applies a second storage space II which can meet the size required by the application B, and stores the audio data format two included in the recording request 2 in the second storage space II. The electronic device processes a sub-audio signal b of the voice input by the user to the application B according to the audio data format one in the recording request 1, and stores the processed sub-audio signal b into the first storage space. Further, the electronic device directly stores the sub-audio signal a in the first storage space into the second storage space I, and reads the audio data processing format two from the second storage space II, processes the sub-audio signal b in the first storage space according to the audio data processing format two, and stores the processed sub-audio signal b into the second storage space II.

[0100] In one embodiment of the present application, the step S2100 is implemented by the following step S2120.

[0101] Step S2120, in the case of receiving a recording request sent by at least one application, applying a first storage space according to a first recording request.

[0102] The first recording request is the first received recording request.

[0103] In this embodiment, the first received recording request is recorded as the first recording request.

[0104] In this embodiment, a storage space which can at least meet the size required by the application sending the first recording request is applied according to the first recording request, as the first storage space, so that the first storage space can at least store the audio signal of the voice input by the user to the application corresponding to the first recording request.

[0105] In one embodiment of the present application, the recording method provided by the present application further includes the following steps S2600 and / or step 2700.

[0106] Step S2600, in the case of receiving the recording end request sent by any application program, releasing the second storage space corresponding to the application program.

[0107] Step S2700, in the case of receiving the recording end request sent by all application programs, closing the microphone and releasing the first storage space.

[0108] In the embodiment, in the case of receiving the recording end request sent by any application program, the second storage space corresponding to the application program is released, so that the resource of the second storage space is released, and unnecessary occupation of the storage space in the electronic device is avoided.

[0109] In addition, in the case of receiving the recording end request sent by all application programs which have sent the recording request, the first storage space is released, so that the resources of the first storage space and all the second storage spaces are released, and unnecessary occupation of the storage space in the electronic device is avoided. Meanwhile, in the case of receiving the recording end request sent by all application programs which have sent the recording request, the microphone is closed, so that unnecessary occupation of the microphone is avoided.

[0110] On the basis of the above, the program voice implementation mode of the recording method provided by the application can be specifically shown in FIG. 3. APP1 first sends a recording request to the electronic device, the electronic device calls the AudioRecord function according to the recording request, the AudioRecord function starts the microphone, applies the Sample Buffer as the first storage space, and applies the APP1 Buffer as the second storage space.
