[0044] The present invention will be described in detail below through examples.

[0045] A burning device is a device that can burn various types of data, for example, burning audio. In related technologies, audio is stored in terminals such as mobile phones, and the process of burning the audio by the burning device is usually as follows: the terminal uses a speaker to play the audio, the burning device records the played audio through recording software, and saves the recorded audio, thereby completing the audio burning process.

[0046] However, the recording method of playing audio externally and then recording it will cause the audio to attenuate and be contaminated by noise during the audio playback process, which will cause the recorded audio to be distorted or noisy, and cannot meet the requirements of high-precision audio signal analysis. For example, in the scenario of voiceprint matching, voiceprint matching cannot be performed due to the poor quality of the recorded audio signal.

[0047] In order to solve the above-mentioned technical problems existing in the related art, the embodiment of the present invention directly connects the terminal and the audio signal burning device through an audio signal converter, thereby solving the problems of audio signal distortion and audio signal noise caused by the external playback and then burning of the terminal audio signal in the related art, and meeting the high requirements of audio signal analysis such as voiceprint matching. In addition, the embodiment of the present invention uses an audio signal converter to physically connect the terminal and the audio signal burning device, so that the audio signal has a stronger anti-interference ability and lower latency. And there is no need to match the connection device on the terminal to avoid leaving traces of operation. In addition, the audio signal burning system provided by the embodiment of the present invention has low hardware complexity, which greatly reduces production costs.

[0048] The overall technical solution of an embodiment of the present invention will be explained in detail below. The technical solution of an embodiment of the present invention involves a terminal, an audio signal converter and an audio signal recording device. The connection relationship among the terminal, the audio signal converter and the audio signal recording device and the transmission process of the audio signal will be introduced below.

[0049] Firstly, the connection relationship among the terminal, the audio signal converter and the audio signal recording device is explained.

[0050] The first step is to determine the audio signal output interface type of the terminal. In actual applications, the audio signal output interface of the terminal may include many types of interfaces, such as a 3.5 mm audio interface (can be called a 3.5 mm audio interface), a lightning interface (can be called a Lightning interface), and a USB-C interface.

[0051] The second step is to select a suitable converter cable. In order to describe the solution clearly, the converter cable can be called the first converter cable. One end of the first converter cable is connected to the converter, and the other end is adapted to the audio signal output interface of the terminal. Since there are many types of interface types of the audio signal output interface of the terminal, it is necessary to select a suitable first converter cable to find a connection interface that is adapted to the interface type of the audio signal output interface of the terminal. For example, if the interface type of the audio signal output interface of the terminal is a 3.5mm audio interface, then the interface of the first converter cable connected to the audio signal output interface of the terminal should be a 3.5mm audio interface.

[0052] In the third step, after selecting a suitable first converter connection line in the second step, the first converter connection line can be directly connected to the audio signal output interface of the terminal. In addition, it is necessary to ensure that the first converter connection line is in stable contact with the audio signal output interface of the terminal to avoid interruption of audio signal transmission or loss of audio signal quality during the process of the terminal transmitting signals to the audio signal converter through the first converter connection line.

[0053] The fourth step is to select a converter cable for connecting the audio signal converter and the audio signal recording device. For the sake of clarity in the scheme description, the converter cable is referred to as a second converter cable. In the embodiment of the present invention, the output interface of the second converter cable is a 3.5 mm output interface, and the audio signal converter is connected to the audio signal recording device through the 3.5 mm output interface of the second converter cable. The audio signal receiving port of the audio signal recording device is also a 3.5 mm output interface.

[0054] The connection between the terminal, the audio signal converter and the audio signal recording device is realized through the above four steps. Next, the audio signal transmission process between the terminal, the audio signal converter and the audio signal recording device is introduced. Figure 1 FIG. 1 is a schematic diagram of the transmission process of an audio signal in a terminal, an audio signal converter, and an audio signal recording device. The transmission process of an audio signal includes the following steps:

[0055] The first step is to play the audio signal to be transcribed on the terminal.

[0056] The terminal has an audio playback module, which can play the audio signal to be transcribed, and the audio signal can be an audio signal in an audio or video or a chat voice, which is reasonable. In addition, when playing the audio signal to be transcribed, the terminal sends the audio signal being played to the audio signal converter through the audio signal output interface.

[0057] In the second step, the audio signal is transmitted from the audio signal output interface of the terminal to the audio signal converter output channel, and then transmitted to the audio signal input channel through a high-precision circuit processing module, such as Figure 2 In addition, during the audio signal transmission process, no signal processing operation is performed to ensure full-link lossless transmission of the audio signal from the terminal to the audio signal converter. Figure 2 The figure shows the internal structure of the audio signal converter. Figure 2 The 3.5mm interface, Lightning interface and USB-C interface are used to connect to the terminal. Figure 2 The 3.5mm audio signal output port is used to connect to an audio signal recording device.

[0058] The third step is that the audio signal recording device realizes lossless audio signal capture. Specifically, the audio signal recording device is equipped with a high-precision audio signal receiving module, which can directly capture the original audio signal without any processing from the audio signal converter. In addition, the audio signal converter can ensure that during the audio signal capture process, there is no sound quality loss caused by audio signal compression, conversion or processing, and maintain the purity of the audio signal.

[0059] In the fourth step, the audio signal recording device records the audio signal to obtain the recorded audio signal and saves the recorded audio signal.

[0060] Specifically, any device with a 3.5mm interface and recording software can be the audio signal recording device of the embodiment of the present invention, and can record the input audio signal through the recording software. Therefore, it has wider versatility.

[0061] The audio recording device directly receives and records the audio signal transmitted through the 3.5mm interface without any form of audio signal processing or format conversion. The recorded and saved audio file format is an uncompressed original audio format, such as waveform sound file WAV and AIFF (Audio Interchange File Format) and other lossless formats to ensure the originality and highest fidelity of the audio signal.

[0062] Moreover, in practical applications, a one-key start burning function can be provided to simplify the operation process and facilitate the rapid completion of the burning of the audio signal while ensuring the originality and integrity of the audio signal.

[0063] The embodiment of the present invention directly connects the terminal and the audio signal recording device through an audio signal converter. The audio signal recorded by the audio signal recording device has high originality and integrity, that is, the quality of the recorded audio signal is high, which solves the problems of audio signal distortion and noise in the audio signal caused by external playback and re-recording of the terminal audio signal in the related art, and meets the high requirements of audio signal analysis such as voiceprint matching. In addition, the embodiment of the present invention directly connects the terminal and the audio signal recording device physically through an audio signal converter, so that the audio signal has stronger anti-interference ability and lower latency. And there is no need to match the connection device on the terminal to avoid leaving traces of operation. In addition, the hardware complexity is low, which greatly reduces the production cost.

[0064] Furthermore, in order to meet the personalized needs of users, the audio signal converter can not only obtain the audio to be recorded from the terminal, but also obtain the audio processing file for the audio to be recorded from the terminal. At this time, the interaction steps among the terminal, the audio signal converter and the audio signal recording device can be as follows: Figure 3 shown.

[0065] The first step is to play the audio to be burned on the terminal.

[0066] Among them, the terminal has an audio playback module, which can play the audio to be burned, and the audio can be the audio in the audio and video or the chat voice, which is reasonable. In addition, the user can set the target instruction on the terminal through the preset operation, and the target instruction is used to indicate that the audio to be burned is processed according to the audio processing method set by the user. After receiving the target instruction set by the user, the terminal can generate an audio processing file, which includes the audio processing method set by the user. Among them, there can be multiple audio processing methods, for example, it can be to keep the original audio content of the audio signal to be burned, it can also be to change the voice of the audio signal to be burned, it can also be to add background sound effects to the audio signal to be burned, or, to add music of instructions to the audio signal to be burned, etc., which are all reasonable. Of course, in practical applications, there can be many audio processing methods, which are not listed one by one here.

[0067] When the terminal is playing the audio signal to be burned, it sends the audio to be burned and the audio processing file being played to the audio signal converter through the audio signal output interface, so that in the subsequent steps, the audio signal burning device processes the audio to be burned based on the audio processing method included in the audio processing file, and then burns the processed audio to be burned.

[0068] In the second step, the audio and audio processing files to be burned are transmitted from the audio signal output interface of the terminal to the audio signal converter output channel, and then transmitted to the audio signal input channel through a high-precision circuit processing module. In addition, no signal processing operation is performed during the audio signal transmission process to ensure full-link lossless transmission of the audio signal from the terminal to the audio signal converter.

[0069] The third step is that the audio signal recording device realizes lossless audio signal capture. Specifically, the audio signal recording device is equipped with a high-precision audio signal receiving module, which can directly capture the original audio signal and audio processing file without any processing from the audio signal converter. In addition, the audio signal converter can ensure that there is no sound quality loss due to audio signal compression, conversion or processing during the audio signal capture process, and maintain the purity of the audio signal.

[0070] In the fourth step, after receiving the audio signal to be recorded and the audio processing file, the audio signal recording device can parse the audio processing file to obtain the audio processing method included in the audio processing file, and process the audio signal to be recorded according to the audio processing method obtained by the analysis to obtain the processed audio signal to be recorded, and then record the audio signal to be recorded to obtain the recorded audio signal, and save the recorded audio signal. The format of the recorded audio signal can be a waveform sound file WAV and AIFF (Audio Interchange File Format), etc., which is not specifically limited in the embodiment of the present invention.

[0071] In practical applications, any device with a 3.5mm interface and recording software can be the audio signal recording device of the embodiment of the present invention, and can record the input audio signal through the recording software, so it has wider versatility. In addition, the audio signal recording device can provide a one-key start recording function to simplify the operation process and facilitate the rapid completion of audio signal recording.

[0072] The technical solution provided by the embodiment of the present invention directly connects the terminal and the audio signal burning device through an audio signal converter, and the quality of the audio signal burned by the audio signal burning device is high, that is, the burned audio signal will not be distorted and has no noise. In addition, the user can set a target instruction at the terminal, and the target instruction is used to indicate that the audio to be burned is processed by the audio processing method in the target audio processing file, that is, the audio to be burned can be processed according to the user instruction. After the audio signal converter obtains the audio signal to be burned and the target instruction from the terminal, it can process the audio to be burned according to the audio processing method indicated by the target instruction to obtain the processed audio to be burned; burn the processed audio to be burned to obtain the burned audio, and save the burned audio. It can be seen that in the embodiment of the present invention, the content of the burned audio is diversified and can meet the personalized needs of users.

[0073] Furthermore, the embodiment of the present invention directly connects the terminal and the audio signal recording device physically through the audio signal converter, so that the audio signal has stronger anti-interference ability and lower delay. In addition, the audio signal recording system provided by the embodiment of the present invention has low hardware complexity, which greatly reduces production costs.

[0074] After the overall technical solution of the present invention is described in detail, an audio signal recording system and method provided by an embodiment of the present invention are introduced below.

[0075] Firstly, an audio signal recording system provided by the present invention is described in detail.

[0076] The embodiment of the present invention provides an audio signal recording system 40, such as Figure 4 As shown, the audio signal recording system 40 includes an audio signal converter 401 and an audio signal recording device 402; the audio signal converter 401 is connected to the terminal via a first converter connection line, and the audio signal converter 401 is connected to the audio signal recording device 402 via a second converter connection line.

[0077] The audio signal converter 401 is used to obtain the audio signal to be recorded from the terminal through the first converter connection line during the process of the terminal playing the audio signal to be recorded.

[0078] The audio signal converter 401 is further used to send the audio signal to be recorded to the audio signal recording device 302 through the second converter connection line.

[0079] The audio signal recording device 402 is used to receive the audio signal to be recorded, record the audio signal to be recorded, obtain the recorded audio signal, and save the recorded audio signal.

[0080] The audio format of the recorded audio signal is the same as that of the audio signal to be recorded, and the recorded audio signal is not compressed.

[0081] Specifically, the audio signal recording system includes an audio signal converter and an audio signal recording device. The audio signal converter in the audio signal recording system is connected to a terminal via a first converter connection line to obtain an audio signal to be recorded from the terminal, so that the audio signal recording device records the audio signal to be recorded. In addition, the audio signal converter is connected to the audio signal recording device via a second converter connection line, so that the audio signal recording device can obtain the audio signal to be recorded from the audio signal converter, record the audio signal to be recorded, and save the recorded audio signal.

[0082] After the terminal, the audio signal converter and the audio signal recording device are connected, the terminal can play the audio signal to be recorded. During the process of the terminal playing the audio signal to be recorded, the terminal can send the audio signal to be recorded to the audio signal converter through the first converter connector, so that the audio signal can obtain the audio signal to be recorded. Then, the audio signal converter sends the audio signal to be recorded to the audio signal recording device through the second converter connection line. After receiving the audio to be recorded, the audio signal recording device can record the audio to be recorded, obtain the recorded audio signal, and save the recorded audio signal.

[0083] Furthermore, in order to ensure that the audio signal burned by the audio signal burning device is a lossless audio signal compared to the audio signal to be burned, that is, to ensure that the sound quality of the audio data after burning is high and does not contain noise, the audio signal after burning has the same audio format as the audio signal to be burned, and the audio signal after burning is not compressed.

[0084] The audio signal burning system provided by the embodiment of the present invention directly connects the terminal and the audio signal burning device through an audio signal converter. The audio signal after being burned by the audio signal burning device has high originality and integrity, that is, the quality of the audio signal after being burned is high, which solves the problems of audio signal distortion and noise in the audio signal caused by externally playing and then burning the terminal audio signal in the related art, and meets the high requirements of audio signal analysis such as voiceprint matching. In addition, the embodiment of the present invention directly physically connects the terminal and the audio signal burning device through an audio signal converter, so that the audio signal has stronger anti-interference ability and lower delay. And there is no need to match the connection device on the terminal to avoid leaving traces of operation. In addition, the audio signal burning system provided by the embodiment of the present invention has low hardware complexity, which greatly reduces the production cost.

[0085] In one embodiment, the first converter connection line has connection interfaces of multiple interface types; the audio signal converter is connected to the audio signal output interface of the terminal through the target connection interface of the first converter connection line; the interface type of the target connection interface is adapted to the interface type of the audio signal output interface of the terminal.

[0086] Specifically, the first converter connecting cable can have connection interfaces of various interface types, for example, a 3.5mm interface, a Lightning interface, and a USB-C interface. In this way, for terminals with different interface types, the terminal can be connected to the audio signal burning device through the connection interface adapted by the first converter connecting cable, thereby having wider versatility.

[0087] In one embodiment, the second converter connecting line has a 3.5 mm output interface; the audio signal converter is connected to the audio signal receiving interface of the audio signal recording device through the 3.5 mm output interface of the second converter connecting line; the audio signal receiving interface of the audio signal recording device is a 3.5 mm input interface.

[0088] Specifically, in the embodiment of the present invention, the audio signal converter is connected to the audio signal burning device through the 3.5mm output interface of the second converter connecting line. In this way, any device with a 3.5mm interface and recording software can be the audio signal burning device of the embodiment of the present invention, and can record the input audio signal through the recording software. Therefore, it has a wider versatility.

[0089] In one implementation, the audio signal to be recorded obtained by the audio signal converter from the terminal is the same as the audio signal to be recorded played by the terminal; the audio signal to be recorded received by the audio signal recording device is the same as the audio signal to be recorded played by the terminal.

[0090] In this embodiment, the terminal, the audio signal converter and the audio signal burning device are physically directly connected to achieve lossless transmission of the audio signal to be burned, thereby making the signal quality of the audio signal after burning higher, solving the problems of audio signal distortion and audio signal noise caused by external playback and then burning of the terminal audio signal in the related technology, and meeting the high requirements of audio signal analysis such as voiceprint matching.

[0091] Based on the above embodiment, the audio signal converter can not only obtain the audio to be recorded from the terminal, but also obtain the target audio processing file for the audio to be recorded. Figure 5 As shown, the embodiment of the present invention provides an audio signal recording system 50, such as Figure 5As shown, the audio signal recording system 50 includes an audio signal converter 501 and an audio signal recording device 502; the audio signal converter 501 is connected to the terminal via a first converter connection line, and the audio signal converter 501 is connected to the audio signal recording device 502 via a second converter connection line.

[0092] The audio signal converter 501 is used to obtain the audio to be recorded and the target audio processing file for the audio to be recorded from the terminal through the first converter connection line during the process of the terminal playing the audio to be recorded.

[0093] The target audio processing file is an audio processing file sent to the audio signal converter when the terminal receives a target instruction from the user; the target instruction is used to instruct the audio to be recorded to be processed using the audio processing method included in the target audio processing file.

[0096] The audio signal recording device 502 is further configured to process the audio to be recorded based on the audio processing method to obtain the processed audio to be recorded; record the processed audio to be recorded to obtain the recorded audio, and save the recorded audio.

[0097] Specifically, the audio signal recording system includes an audio signal converter and an audio signal recording device. The audio signal converter in the audio signal recording system is connected to the terminal via a first converter connection line, and the user can set a target instruction on the terminal through a preset operation, and the target instruction is used to instruct to process the audio to be recorded according to the audio processing method set by the user. After receiving the target instruction set by the user, the terminal can generate a target audio processing file, and the target audio processing file includes the audio processing method set by the user. In this way, the audio signal converter can obtain the audio to be recorded and the target audio processing file from the terminal.

[0098] In addition, the audio signal converter is connected to the audio signal burning device via a second converter connecting line, so that the audio signal converter can send the audio to be burned and the target audio processing file to the audio signal burning device via the second converter connecting line, so that the audio signal burning device first performs audio processing on the audio signal to be burned according to the audio processing method, obtains the processed audio to be burned, burns the processed audio to be burned, and saves the burned audio.

[0099] There are many audio processing methods, for example, it can be to keep the original audio content of the audio signal to be recorded, or to change the audio signal to be recorded, or to add background sound effects to the audio signal to be recorded, or to add music of instructions to the audio signal to be recorded, etc. These are all reasonable. Of course, in practical applications, there are many audio processing methods, which are not listed here one by one.

[0100] The technical solution provided by the embodiment of the present invention directly connects the terminal and the audio signal burning device through an audio signal converter, and the quality of the audio signal burned by the audio signal burning device is high, that is, the burned audio signal will not be distorted and has no noise. In addition, the user can set a target instruction at the terminal, and the target instruction is used to indicate that the audio to be burned is processed by the audio processing method in the target audio processing file, that is, the audio to be burned can be processed according to the user instruction.

[0101] Furthermore, the embodiment of the present invention directly connects the terminal and the audio signal recording device physically through the audio signal converter, so that the audio signal has stronger anti-interference ability and lower delay. In addition, the audio signal recording system provided by the embodiment of the present invention has low hardware complexity, which greatly reduces production costs.

[0102] Based on the above embodiment, in one implementation manner, the audio processing method includes adding target audio content to the audio to be recorded and adding corresponding audio parameters when the target audio content is added.

[0103] The audio parameters include the volume and tempo of the target audio content. The target audio content can be background audio such as wind and rain, or some specific music content. It is understandable that in actual applications, users can set the audio content added to the audio to be burned based on their own needs, and no specific limitation is made here.

[0104] In this embodiment, the audio signal recording device is further used to process the audio to be recorded based on the audio processing method to obtain the processed audio to be recorded, which may include the following steps a1 and a2:

[0105] In step a1, the audio signal recording device obtains the target audio content corresponding to the audio processing method and the audio parameters corresponding to adding the target audio content.

[0106] Step a2: the audio signal recording device adds the target audio content to the audio to be recorded according to the audio parameters of the target audio content.

[0107] Specifically, if the audio processing method includes adding target audio content and corresponding audio parameters when adding the target audio content to the audio to be recorded, then the audio signal recording transposition needs to obtain the target audio content and the corresponding audio parameters when adding the target audio content.

[0108] The method for acquiring the target audio content may be: the audio signal recording device may send an acquisition instruction for the target audio content to the audio signal converter. After the audio signal converter acquires the acquisition instruction, it may forward the acquisition instruction to the terminal and acquire the target audio content from the server.

[0109] After the terminal obtains the target audio content, the target audio content can be sent to the audio signal burning device through the audio signal converter. After the audio signal burning device receives the target audio content, it adds the target audio content to the audio to be burned according to the corresponding audio parameters when adding the target audio content, and obtains the processed audio, so that the audio signal burning device can burn the audio to be processed and save the burned audio.

[0110] The audio parameters may include volume, tempo, etc. In practical applications, the volume of the added target audio content should not exceed the volume of the audio to be recorded, so as not to affect the sound quality of the audio to be recorded. When the tempo of the audio to be recorded is fast, the tempo of the added target audio content should also be fast; when the tempo of the audio to be recorded is slow, the tempo of the added target audio content should also be slow.

[0111] It can be seen that, through this embodiment, the audio content specified by the user can be added to the audio to be recorded, so that the recorded audio meets the personalized needs of the user.

[0112] Based on the above embodiment, in one implementation manner, the audio processing method includes audio processing parameters when performing audio processing on the audio to be recorded, and the audio processing parameters include audio frequency parameters and audio timbre parameters;

[0113] At this time, the audio signal recording device is further used to process the audio to be recorded based on the audio processing method to obtain the processed audio to be recorded, which may include the following steps b1 and b2:

[0114] In step b1, the audio signal recording device obtains audio frequency parameters and audio timbre parameters included in the audio processing method.

[0115] Step b2: the audio signal recording device adjusts the frequency and timbre of the audio to be recorded according to the audio frequency parameter and the audio timbre parameter to obtain the processed audio to be recorded.

[0116] Specifically, if the audio processing method includes audio processing parameters for audio processing of the audio to be recorded, and the audio processing parameters include audio frequency parameters and audio timbre parameters, then the audio signal recording device can parse the audio processing method to obtain the audio frequency parameters and audio timbre parameters included in the audio processing method, and change the frequency and timbre of the audio to be recorded according to the audio frequency parameters and audio timbre parameters to obtain the processed audio to be recorded. By adjusting the frequency and timbre of the audio to be recorded, the voice changing processing of the audio to be recorded can be achieved. For example, if the audio to be recorded is a male voice, the audio and timbre of the audio to be recorded can be changed to a female voice. If the audio to be recorded is a female voice, the audio and timbre of the audio to be recorded can be changed to a male voice.

[0117] It can be seen that, through this embodiment, the voice changing processing of the audio to be recorded can be realized, so that the recorded audio meets the personalized needs of the user.

[0118] Based on the above embodiments, in one implementation, the audio signal recording device further includes an audio signal processing model; the audio signal processing model is trained based on a plurality of different audio processing methods and audio signal samples to be processed;

[0119] In this implementation, the audio signal recording device is further used to process the audio to be recorded based on the audio processing method to obtain the processed audio to be recorded, which may include the following step c:

[0120] In step c, the audio signal recording device inputs the audio processing method and the audio to be recorded into the audio signal processing model, so that the audio signal processing model performs audio processing on the audio to be recorded based on the audio processing method, and outputs the processed audio to be recorded.

[0121] Specifically, after obtaining the audio signal to be recorded, the audio signal recording device can input the audio processing method and the audio to be recorded into the audio signal processing model, and the audio signal processing model performs audio processing on the audio to be recorded according to the audio processing method, and then quickly and accurately outputs the processed audio to be recorded. It can be seen that through this embodiment, the audio to be recorded can be quickly and accurately processed through the audio signal processing model, so that the recorded audio meets the personalized needs of the user.

[0122] Next, an audio signal recording method provided by an embodiment of the present invention will be described in detail. The audio signal recording method can be applied to the audio signal recording system in the above embodiment, and the audio signal recording system includes an audio signal converter and an audio signal recording device; the audio signal converter is connected to the terminal through a first converter connection line, and the audio signal converter is connected to the audio signal recording device through a second converter connection line. Figure 6 As shown, the audio signal recording method comprises the following steps:

[0123] S610: When the terminal plays the audio to be recorded, the audio signal converter obtains the audio to be recorded from the terminal through the first converter connection line.

[0124] Specifically, after the terminal, the audio signal converter and the audio signal burning device are connected, the terminal can play the audio to be burned. During the process of the terminal playing the audio to be burned, the terminal can send the audio to be burned to the audio signal converter through the first converter connector, so that the audio signal converter obtains the audio to be burned.

[0125] S620: The audio signal converter sends the audio to be recorded to the audio signal recording device through the second converter connection line.

[0126] Specifically, the audio signal converter sends the audio to be recorded to the audio signal recording device through the second converter connection line, so that the audio signal recording device records the audio to be recorded after receiving the audio to be recorded.

[0127] S630, the audio signal recording device receives the audio to be recorded, records the audio to be recorded, obtains the recorded audio, and saves the recorded audio.

[0128] The audio format of the burned audio is the same as that of the audio to be burned, and the burned audio is not compressed.

[0129] Specifically, after receiving the audio to be recorded, the audio signal recording device can record the audio to be recorded, obtain the recorded audio, and save the recorded audio.

[0130] Furthermore, in order to ensure that the audio signal burned by the audio signal burning device is a lossless audio signal compared to the audio signal to be burned, that is, to ensure that the sound quality of the burned audio data is high and noise-free, the audio format of the burned audio is the same as that of the audio to be burned, and the burned audio signal is not compressed.

[0131] The audio signal burning method provided in the embodiment of the present invention directly connects the terminal and the audio signal burning device through an audio signal converter. The audio after the audio signal burning device has high originality and integrity, that is, the quality of the audio after the burning is high, which solves the problems of audio distortion and audio noise caused by the external audio of the terminal and then burning in the related art, and meets the high requirements of audio signal analysis such as voiceprint matching. In addition, the embodiment of the present invention directly connects the terminal and the audio signal burning device physically through an audio signal converter, so that the audio signal has stronger anti-interference ability and lower delay. And there is no need to match the connection device on the terminal to avoid leaving traces of operation. In addition, the audio signal burning system provided in the embodiment of the present invention has low hardware complexity, which greatly reduces production costs.

[0135] Specifically, the first converter connecting cable can have connection interfaces of various interface types, for example, a 3.5mm interface, a Lightning interface, and a USB-C interface. In this way, for terminals with different interface types, the terminal can be connected to the audio signal burning device through the connection interface adapted by the first converter connecting cable, thereby having wider versatility.

[0136] In one embodiment, the second converter cable has a 3.5 mm output interface;

[0137] S620, the audio signal converter sends the audio to be recorded to the audio signal recording device through the second converter connection line, which may include the following steps:

[0138] The audio signal converter sends the audio to be recorded to the audio signal recording device through the 3.5 mm output interface of the second converter connecting line.

[0139] Specifically, in the embodiment of the present invention, the audio signal converter is connected to the audio signal burning device through the 3.5mm output interface of the second converter connecting line. In this way, any device with a 3.5mm interface and recording software can be the audio signal burning device of the embodiment of the present invention, and can record the input audio signal through the recording software. Therefore, it has a wider versatility.

[0140] In one implementation, the audio signal to be recorded obtained by the audio signal converter from the terminal is the same as the audio signal to be recorded played by the terminal; the audio signal to be recorded received by the audio signal recording device is the same as the audio signal to be recorded played by the terminal.

[0141] In this embodiment, the terminal, the audio signal converter and the audio signal burning device are physically directly connected to achieve lossless transmission of the audio signal to be burned, thereby making the signal quality of the audio signal after burning higher, solving the problems of audio signal distortion and audio signal noise caused by external playback and then burning of the terminal audio signal in the related technology, and meeting the high requirements of audio signal analysis such as voiceprint matching.

[0142] Based on the above embodiment, the audio signal converter can not only obtain the audio to be recorded from the terminal, but also obtain the target audio processing file for the audio to be recorded.

[0143] At this time, if Figure 7 As shown, the audio signal recording method comprises the following steps:

[0144] S710, when the terminal plays the audio to be recorded, the audio signal converter obtains the audio to be recorded and a target audio processing file for the audio to be recorded from the terminal through a first converter connection line.

[0145] The target audio processing file is an audio processing file sent to the audio signal converter when the terminal receives a target instruction from the user; the target instruction is used to instruct the audio to be recorded to be processed using the audio processing method in the target audio processing file.

[0146] There are many target audio processing methods, for example, it can be to keep the original audio content of the audio signal to be recorded, or to change the audio signal to be recorded, or to add background sound effects to the audio signal to be recorded, or to add music of instructions to the audio signal to be recorded, etc. These are all reasonable. Of course, in practical applications, there are many audio processing methods, which are not listed here one by one.

After receiving the target instruction set by the user, the terminal can generate a target audio processing file, and the target audio processing file includes the audio processing method set by the user. In this way, the audio signal converter can obtain the audio to be recorded and the target audio processing file from the terminal.

[0151] In addition, the audio signal converter is connected to the audio signal burning device via a second converter connecting line, so that the audio signal converter can send the audio to be burned and the target audio processing file to the audio signal burning device via the second converter connecting line, so that the audio signal burning device first performs audio processing on the audio signal to be burned according to the audio processing method, obtains the processed audio to be burned, burns the processed audio to be burned, and saves the burned audio.

[0152] The technical solution provided by the embodiment of the present invention directly connects the terminal and the audio signal burning device through an audio signal converter, and the quality of the audio signal burned by the audio signal burning device is high, that is, the burned audio signal will not be distorted and has no noise. In addition, the user can set a target instruction at the terminal, and the target instruction is used to indicate that the audio to be burned is processed by the audio processing method in the target audio processing file, that is, the audio to be burned can be processed according to the user instruction.
