Description

Technical Field

[0001] This application relates to the field of private networks, and in particular to a recording method, a multi-mode terminal, and a storage medium. Background Technology

[0002] In team collaboration scenarios such as industrial production, security patrols, and property management, walkie-talkies are widely used as real-time voice communication tools. Their high immediacy and ease of operation make them core equipment for ensuring the transmission of team instructions and task coordination. With the expansion of application scenarios, users have placed higher demands on the functionality of walkie-talkies, with the preservation of recorded files becoming one of the core requirements.

[0003] Currently, multi-mode terminals are divided into two systems: broadband and narrowband. The two systems operate independently, and all interactive commands require communication through external hardware. The broadband system has the advantages of stronger processing power and larger storage space compared to the narrowband system; while the narrowband system has virtually no additional storage capacity and can only rely on external memory cards.

[0004] Therefore, call recordings for narrowband calls need to be stored in broadband. Due to the inconsistency in processing times between the two systems, the actual recorded audio may be later than the call's occurrence time, thus missing data indicating the call's start. Specifically, first, the user receives audio data through the narrowband module. Second, the narrowband module generates a recording save command based on the user's operation and sends it to the broadband module. Finally, upon receiving the recording save command, the broadband module stores the corresponding audio data as a recording file.

[0005] However, in existing technical solutions, the broadband module only initiates the corresponding audio data storage process after receiving the recording save command. Due to the transmission delay in sending the recording save command from the narrowband module to the broadband module, the broadband module may not trigger the storage operation in time, thus discarding some audio data and ultimately resulting in an incomplete recording file. Summary of the Invention

[0006] This application provides a recording method, a multi-mode terminal, and a storage medium, aiming to solve the technical problem of incomplete recording files in the prior art.

[0007] In a first aspect, embodiments of this application provide a recording method, the method being applied to a multi-mode terminal, the multi-mode terminal comprising: a narrowband module and a broadband module, the method comprising: The narrowband module receives voice calls from the target user; The broadband module performs valid audio data detection on the audio path; When valid audio data is detected in the audio path at the first moment, the audio data in the audio path is cached in the target buffer. When it is detected at the second moment that there is no valid audio data in the audio path, the caching of audio data in the audio path to the target buffer is stopped. The second moment is after the first moment. If the broadband module receives a recording instruction from the narrowband module before the second moment, it saves the audio data in the target buffer as an audio file based on the recording instruction.

[0008] Optionally, the method further includes: If the broadband module does not receive a recording instruction from the narrowband module before the second time point, the audio data in the target buffer is cleared.

[0009] Optionally, the valid audio data detection of the audio path includes: Obtain the target audio data frame from the audio path; Valid audio data detection is performed on the target audio data frame.

[0010] Optionally, the valid audio data detection of the target audio data frame includes: Detect the binary data corresponding to the audio data of the target audio data frame; If the binary data corresponding to the audio data of the target audio data frame is all zeros, or if the binary data corresponding to the audio data of the target audio data frame is all ones, then it is determined that the target audio data frame does not contain valid audio data. If the binary data corresponding to the audio data of the target audio data frame is not all zeros, and the binary data corresponding to the audio data of the target audio data frame is not all ones, then it is determined that the target audio data frame contains valid audio data.

[0011] Optionally, the method further includes: During the time interval between the first time and the second time, the broadband module acquires the identity information of the target user from the narrowband module; The audio file is bound to the identity information to obtain the binding information of the target user; Store the binding information of the target user.

[0012] Optionally, before binding the audio file with the identity information to obtain the binding information of the target user, the method further includes: During the time interval between the first time and the second time, the broadband module receives the location information of the target user from the narrowband module; The step of binding the audio file with the identity information to obtain the binding information of the target user includes: The audio file, the identity information, and the location information are bound together to obtain the binding information of the target user.

[0013] Optionally, when the voice call is a group call, the method further includes: Obtain the binding information of multiple group members in the group corresponding to the group call; Generate a target group chat recording file corresponding to the group call based on the binding information of the multiple group members; Based on the identity information of the group members, the group chat recording file is presented to the user of the multi-mode terminal.

[0014] Secondly, embodiments of this application also provide a multi-mode terminal, including: a narrowband module and a broadband module, wherein, The narrowband module is used to receive voice calls from the target user; The broadband module is used to detect valid audio data in the audio channel; when valid audio data is detected in the audio channel at a first moment, the audio data in the audio channel is cached in the target buffer; when valid audio data is detected not in the audio channel at a second moment, the caching of audio data in the audio channel in the target buffer is stopped, and the second moment is after the first moment. If the broadband module receives a recording instruction from the narrowband module before the second moment, it saves the audio data in the target buffer as an audio file based on the recording instruction.

[0015] Optionally, if the broadband module does not receive a recording instruction from the narrowband module before the second time point, the audio data in the target buffer is cleared.

[0016] Thirdly, embodiments of this application also provide a computer-readable storage medium storing a computer program that, when executed by a processor, can implement the above-described method.

[0017] This application provides a recording method, a multi-mode terminal, and a storage medium. The method is applied to a multi-mode terminal, which includes a narrowband module and a wideband module. The method includes: the narrowband module receiving a voice call from a target user; the wideband module detecting valid audio data in an audio path; when valid audio data is detected in the audio path at a first moment, starting to cache the audio data in the audio path in a target buffer; when no valid audio data is detected in the audio path at a second moment, stopping the caching of the audio data in the audio path in the target buffer, the second moment being after the first moment; if, before the second moment, the wideband module receives a recording instruction from the narrowband module, saving the audio data in the target buffer as an audio file based on the recording instruction. Therefore, in this application's technical solution, the narrowband module receives a group call from a target user; then, the wideband module detects valid audio data in the audio path; when valid audio data is detected in the audio path at a first moment, starting to cache the audio data in the audio path in a target buffer; when no valid audio data is detected in the audio path at a second moment, stopping the caching of the audio data in the audio path in the target buffer. In this process, the second time step occurs after the first time step. Finally, if the broadband module receives a recording command from the narrowband module before the second time step, it saves the audio data in the target buffer as an audio file based on the recording command. Therefore, this technical solution performs valid audio data detection on the audio path. When valid audio data is detected in the audio path at the first time step, it begins caching the audio data in the target buffer. When no valid audio data is detected in the audio path, it stops caching the audio data in the target buffer. Thus, in this technical solution, the broadband module can start the audio data storage process without waiting for a recording command to be triggered. This mechanism effectively avoids the failure to trigger the storage operation in a timely manner due to transmission delays in the recording command, thereby ensuring the integrity of the recording file.

[0028] To address the technical problem of incomplete audio recordings in existing technologies, this application provides an audio recording device that ensures the integrity of audio recordings.

[0029] Figure 1a This is a flowchart illustrating a recording method provided in an embodiment of this application. In one embodiment, the method is applied to a multi-mode terminal, which includes a narrowband module and a broadband module, and the method includes steps S101-S105.

[0030] S101, Narrowband module receives voice calls from target users.

[0031] It should be noted that the recording method in this application embodiment can be applied to multi-mode terminals. The multi-mode terminal can be a walkie-talkie or a mobile device such as a mobile phone. This application does not impose any limitations on this. Below, this application will use a multi-mode walkie-talkie as an example to describe a recording method in detail.

[0032] In a multi-mode walkie-talkie, the present application example can receive voice calls from a target user through a narrowband module. The voice data of the voice call is sent to an audio codec via the narrowband module, and then sent to an audio accessory, such as a speaker, via the codec.

[0033] S102. Detect effective audio data in the audio path.

[0034] Specifically, when the narrowband module receives a voice call from a target user, the audio path is opened. The wideband module then begins valid audio data detection within the audio path.

[0035] It should be noted that both the narrowband module and the broadband module have their own audio paths for transmitting audio data, and they are both independent and integrated. The broadband module and the narrowband module are also connected via an audio bus. In one embodiment, the narrowband module and the broadband module are connected via both a digital audio bus and an audio connection simulated by an audio codec. The audio path described in this application refers to the data path that transmits the voice data of the narrowband module or the broadband module currently receiving a voice call. Specifically, after the narrowband module receives a voice call, the broadband module can obtain the voice data received by the narrowband module through the audio path.

[0036] It should be noted that the detection process of valid audio data in the audio path will be described in detail in subsequent embodiments of this application. Therefore, it will not be repeated here.

[0037] S103. When valid audio data is detected in the audio path at the first moment, the audio data in the audio path is cached in the target buffer.

[0038] The target buffer is the data buffer of the broadband module. The initial first moment is the time when the broadband module first detects valid audio data in the audio path after the narrowband module receives the call command from the target user. After this initialization, the first moment is the time when the broadband module first detects valid data after detecting invalid data in the audio path.

[0039] S104. When it is detected at the second moment that there is no valid audio data in the audio path, stop caching the audio data in the audio path in the target buffer.

[0040] The second time point is defined as the time following the first time point. The second time point is the time after the first time point when no valid audio data is detected in the audio path for the first time.

[0041] It should be noted that, in this embodiment, the broadband module can stop buffering audio data in the audio path in the target buffer without waiting for a stop recording command. This mechanism effectively avoids the transmission delay caused by the narrowband module's stop recording command being transmitted to the broadband module, which could lead to excessively long recording times in the broadband-saved recording files and the saving of invalid data.

[0042] S105. If the broadband module receives a recording instruction from the narrowband module before the second moment, it saves the audio data in the target buffer as an audio file based on the recording instruction.

[0043] For example, if the second time point is 10 o'clock, and the broadband module has received the recording instruction from the narrowband module before 10 o'clock, the broadband module will save the audio data in the target buffer as an audio file; otherwise, it will clear the audio data in the target buffer to prepare for the next storage of audio data in the audio channel.

[0044] This application provides a recording method. The method is applied to a multi-mode terminal, which includes a narrowband module and a wideband module. The method includes: the narrowband module receiving a voice call from a target user; the wideband module detecting valid audio data in an audio path; when valid audio data is detected in the audio path at a first moment, the module begins caching the audio data in the audio path into a target buffer; when no valid audio data is detected in the audio path at a second moment, caching the audio data in the audio path into the target buffer stops, the second moment being after the first moment; if the wideband module receives a recording instruction from the narrowband module before the second moment, the module saves the audio data in the target buffer as an audio file based on the recording instruction. Therefore, in this application's technical solution, the narrowband module receives a voice call from a target user; then, the wideband module detects valid audio data in the audio path; when valid audio data is detected in the audio path at a first moment, the module begins caching the audio data in the audio path into a target buffer; when no valid audio data is detected in the audio path at a second moment, the module stops caching the audio data in the audio path into the target buffer. In this process, the second moment occurs after the first moment. Finally, if the broadband module has received a recording command from the narrowband module before the second moment, it saves the audio data in the target buffer as an audio file based on the recording command. Therefore, this technical solution performs valid audio data detection on the audio path. When valid audio data is detected in the audio path at the first moment, it begins caching the audio data in the target buffer. When no valid audio data is detected in the audio path, it stops caching the audio data in the target buffer. Thus, in this technical solution, the broadband module can start the pre-storage process of audio data without waiting for a recording command. If a recording command is received, it saves the audio data in the target buffer as a recording file. This mechanism effectively avoids the problem of data not being recorded at the start of a call due to transmission delays in the transmission of recording commands from the narrowband module to the broadband module. It also solves the problem of recording continuing after the call ends or the user stops recording due to transmission delays in the transmission of recording end commands from the narrowband module to the broadband module, resulting in invalid data being recorded. This ensures the integrity and validity of the recording file.

[0045] In one embodiment, the method further includes: S106.

[0046] S106. If the broadband module does not receive a recording instruction from the narrowband module before the second moment, then clear the audio data in the target buffer.

[0047] In this embodiment, the audio data in the target buffer is cleared to prepare for the next storage of audio data in the audio channel.

[0048] In one embodiment, S102 specifically includes the following steps: S1021-S1022.

[0049] S1021. Obtain the target audio data frame from the audio path.

[0050] In this embodiment, multiple audio data frames are periodically acquired from the audio path. Then, valid audio data detection is performed on each audio data frame. The multiple audio data frames include a target audio data frame.

[0051] S1022, Perform valid audio data detection on the target audio data frame.

[0052] It should be noted that this application will take the target audio data frame as an example to explain in detail how to perform effective audio data detection on the target audio data frame.

[0053] In one embodiment, S1022 specifically includes the following steps: S10221-S10223.

[0054] S10221. Detect the binary data corresponding to the audio data of the target audio data frame; S10222. If the binary data corresponding to the audio data of the target audio data frame is all zeros, or if the binary data corresponding to the audio data of the target audio data frame is all ones, then it is determined that the target audio data frame does not contain valid audio data.

[0055] S10223. If the binary data corresponding to the audio data of the target audio data frame is not all zeros and the binary data corresponding to the audio data of the target audio data frame is not all ones, then it is determined that the target audio data frame contains valid audio data.

[0056] It should be noted that S10221-S10223 will be explained in detail below.

[0057] The target audio data frame includes a frame header and payload data, where the payload data is audio data. If all the binary data corresponding to the audio data in the target audio data frame is 1, or if all the binary data corresponding to the audio data in the target audio data frame is 0, then the target audio data frame does not contain valid audio data; otherwise, the target audio data frame contains valid audio data.

[0058] In one embodiment, the method further includes: S107-S109.

[0059] S107. During the time interval between the first and second moments, the broadband module obtains the identity information of the target user from the narrowband module.

[0060] In one embodiment, the broadband module sends the target user's identity information to the narrowband module within the time interval when saving the audio data in the target buffer.

[0061] In another embodiment, when the narrowband module obtains the identity information of the target user of the audio data, it sends the identity information to the broadband module. The broadband module obtains the identity information of the target user when writing audio data to the target buffer.

[0062] S108. Bind the audio file with the identity information to obtain the binding information of the target user.

[0063] S109. Store the binding information of the target user.

[0064] It should be noted that S107-S109 will be explained in detail below.

[0065] The narrowband module can actively send the target user's identity information to the broadband module, or passively respond to a request from the broadband module and send the target user's identity information to the broadband module. In this embodiment, the audio file and the target user's identity information are bound together to obtain the target user's binding information, which is then stored in a database. Users can identify the speaker corresponding to the audio file based on the audio file, and can also retrieve audio files related to the speaker based on the speaker's identity information.

[0066] It's important to note that one audio file corresponds to one speaker. One speaker can correspond to multiple audio files. For conversational recordings, multiple audio clips need to be recorded during a complete call. Each audio clip corresponds to one audio file. For group calls, each audio clip from each member in the group is saved as a separate audio file. Users can clearly view the speaking details of a particular member.

[0067] In yet another embodiment, the method further includes: S110.

[0068] S110, during the time interval between the first and second moments, the broadband module acquires the location information of the target user from the narrowband module.

[0069] The above S108 specifically includes the following steps: S1081.

[0070] S1081. Bind the audio file, identity information, and location information to obtain the binding information of the target user.

[0071] In one embodiment, audio files, identity information, and location information are bound together to obtain the binding information of a target user, which is then stored in a database. The location information can be the latitude and longitude of the speaker. Users can determine the location of the speaker based on the audio file, and can also retrieve audio files related to the speaker based on the speaker's identity information.

[0072] In another embodiment, when the voice call is a group call, the method further includes: S111-S113.

[0073] S111. Obtain the binding information of multiple group members in the corresponding group for the group call.

[0074] S112. Generate a target group chat recording file corresponding to the group call based on the binding information of multiple group members.

[0075] S113. Based on the identity information of the group members, present the group chat recording file to the user of the multi-mode terminal.

[0076] It should be noted that S111-S113 will be explained in detail below.

[0077] Please see Figure 1b , Figure 1b This embodiment of the application provides a UI diagram of a group chat session. When a target user initiates a group call, this embodiment obtains the binding information of multiple group members in the group call. These multiple group members are all members who have spoken in the group corresponding to the group call. The binding information of each group member includes their audio file, identity information, and / or location information. Finally, this embodiment generates a target group chat session recording file corresponding to the group call based on the binding information of the multiple group members, and presents the group chat session recording file to the user of the multi-mode terminal based on the identity information of the group members. In other words, users can know which user sent voice data at what time or from what location through the group chat session, facilitating subsequent tracing or viewing.

[0078] It should be noted that when a target user initiates a call, this embodiment of the application can obtain the target user's binding information and the machine's binding information, and generate a chat session corresponding to the call.

If the broadband module 202 receives a recording instruction from the narrowband module 201 before the second moment, it saves the audio data in the target buffer as an audio file based on the recording instruction.

[0080] In one embodiment, if the broadband module 202 does not receive a recording instruction from the narrowband module 201 before the second moment, the audio data in the target buffer is cleared.

[0081] In one embodiment, the broadband module 202 is specifically used for: Obtain the target audio data frame from the audio path; Valid audio data detection is performed on the target audio data frame.

If the binary data corresponding to the audio data of the target audio data frame is not all zeros, and the binary data corresponding to the audio data of the target audio data frame is not all ones, then it is determined that the target audio data frame contains valid audio data.
