[0003] Audio Vivid technology is a Chinese 3D sound technology solution drafted by China Central Radio and Television. It is also the world's first audio codec standard based on AI technology. It supports mainstream 3D sound coding and is compatible with mono, dual-channel, surround sound, and 3D sound. It can accurately place or move sound in any position in 3D space, and accurately describe the position, size, trajectory, time, and length of each sound by recording metadata information. Compared with traditional horizontal plane sound formats, it adds height information and optimizes the presentation of spatial and directional sense, thereby better meeting the audience's demand for high sound restoration and high immersion experience.

[0004] The main problem existing in the prior art is: when we want to enjoy the sound effects of Audio Vivid 7.1.4, we need to connect the 12 audio cables of the audio playback device to the audio power amplifier device one by one to play Audio Vivid ‌7.1.4 normally. The connection work is cumbersome. Once the connection is wrong, the audio channels will be disordered and the Audio Vivid ‌7.1.4 cannot be played normally, which will consume a lot of manpower and time.

[0005] The difficulty of solving the above problems and defects is: in order to realize the automatic configuration of Jingcaisheng multi-channel audio, it is necessary to develop a set of automatic audio recognition software in Bohua Jingcaisheng Audio Vivid ‌7.1.4 audio player, integrate the audio channel automatic configuration algorithm, and realize the audio channel redirection function.

[0009] Optionally, in the above-mentioned automated configuration method for Jingcaisheng multi-channel audio, first, a 500 Hz sine wave audio is emitted from the first channel of the audio playback device to the power amplifier device, the power amplifier device emits audio from any one of the speakers, the audio playback device receives the 500 Hz sine wave audio through the front microphone, and calculates the direction to obtain which channel speaker of the power amplifier device is currently emitting sound, and then the audio playback device calls the system audio interface to redirect the channel audio; then the second channel of the audio playback device emits a 500 Hz sine wave, and the above steps are repeated to perform the above operations on all 12 channels of the audio playback device.

[0010] Optionally, in the above-mentioned automatic configuration method for the Audio Vivid multi-channel audio, the playback device is the Bohua Audio Vivid ‌7.1.4 audio player.

[0011] Optionally, in the above-mentioned automatic configuration method for the Jingcaisound multi-channel audio, the channels of the audio playback device consist of 7 main audio channels, 1 bass channel and 4 sky channels.

[0014] In order to better understand and illustrate the concept, working principle and effect of the present invention, the present invention is described in detail below through specific embodiments in conjunction with the accompanying drawings: BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to more clearly illustrate the specific implementation of the present invention or the technical solution in the prior art, the drawings required for use in the specific implementation or the description of the prior art are briefly introduced below.

[0016] Figure 1 The audio-visual room is equipped with Audio Vivid ‌7.1.4-channel sound system; Figure 2 This is a block diagram of the connection between the Audio Vivid ‌7.1.4 audio player, 12-channel amplifier, and 12-channel speakers. DETAILED DESCRIPTION

[0017] In order to make the purpose, technical method and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with the accompanying drawings and specific examples. These examples are only illustrative and not limiting of the present invention.

[0018] The present invention provides an automated configuration method for the multi-channel audio of Audio Vivid by using an automated audio channel configuration algorithm to output audio to each channel of an audio playback device, and then receive the audio through a microphone of the audio playback device to determine whether the current connection is correct. If it is incorrect, the audio of the channel will be reallocated. The above operation is performed on all 12 channels of the audio playback device (preferably the Bohua Audio Vivid ‌7.1.4 audio player) to achieve automated audio channel configuration.

[0019] Figure 1 The audio-visual room is equipped with Audio Vivid ‌7.1.4 channels, with a total of 12 speakers. Figure 1 It can be seen that the Audio Vivid ‌7.1.4 channels‌ consist of 7 main audio channels, 1 bass channel and 4 sky channels. Specifically: ‌7 main audio channels‌ include left, right, center, left surround, right surround, left rear surround, and right rear surround. These channels work together to establish a relatively balanced and more surround sound field around the listener. ‌1 bass channel‌, that is, the subwoofer, is responsible for providing deep sound effects and enhancing the expressiveness of the bass part. ‌4 sky channels‌, including front high left, front high right, rear high left, and rear high right. These channels are located above the listener, providing the listener with sound effects from the sky, further enhancing the spatial sense and immersiveness of the sound.

[0020] Figure 2This is a diagram of the connection between the Audio Vivid ‌7.1.4 audio player and the 12-channel amplifier and 12-channel speakers. The connection between the 12-channel amplifier and the 12-channel speakers is fixed via audio speaker cables and arranged at Figure 1 In the audio-visual room, normally no change is required; and the connection between the audio player and the 12-channel power amplifier uses an audio connection line. In a general audio player, each channel connection of the device needs to correspond to the position of the 12-channel power amplifier and the 12-channel speaker one by one, while in the Audio Vivid ‌7.1.4 audio player of Jingcaisheng, an audio channel automatic configuration algorithm is integrated, so the connection with the 12-channel power amplifier can be out of order. In the existing method, only by matching the 12 audio cables of the audio player with the power amplifier one by one can the Audio Vivid ‌7.1.4 of Jingcaisheng be played normally, and the connection work is cumbersome. In order to save time and improve efficiency, the present invention proposes an automatic configuration method for the multi-channel audio of Jingcaisheng Audio Vivid, which can arbitrarily connect 12 audio cables to the audio power amplifier device. Through the audio channel automatic configuration algorithm, the channels of the audio playback device are reordered to achieve the correct connection with the power amplifier device, which greatly reduces the complexity of the audio connection of the device, reduces human resource consumption, and reduces time cost.

[0021] The specific operation method of the automatic configuration of Audio Vivid multi-channel audio is as follows: first, connect the 12 audio cables of the audio player to the power amplifier device at will, and run the audio channel automatic configuration algorithm in the audio player.

[0022] The specific principle of the audio channel automatic configuration algorithm is as follows: First, a 500hz sine wave audio is sent from the first channel of the audio player to the power amplifier device. The power amplifier device sends audio from any speaker. The audio player receives the 500hz sine wave audio through the front microphone, calculates the position to obtain which channel of the power amplifier device is currently sounding, and then redirects the channel through the audio player calling the system audio interface. For example: the first channel of the audio player sends a 500hz sine wave, and the microphone receives the 5-channel audio of the power amplifier speaker. Therefore, the first channel is redirected to the 5th channel on the audio player to achieve the correct 5th channel audio output of Audio Vivid. Then the second channel of the audio player sends a 500hz sine wave, repeat the above steps, and perform the above operations on all 12 channels of the audio player to achieve the correct 7.1.4 channel audio output of Audio Vivid. The automatic configuration of Audio Vivid multi-channel audio is realized.

[0023] The above description is the best embodiment based on the concept and working principle of the invention. The above embodiment should not be understood as limiting the protection scope of the present claims, and other implementations and combinations of implementations according to the concept of the present invention belong to the protection scope of the present invention.
