It should be noted that the following embodiments can refer to, draw on or combine with each other, and the same terms, similar features and similar implementation steps in different embodiments will not be described repeatedly.

[0037] The audio transmission method, device, medium and product provided in this application are intended to solve at least one technical problem existing in the prior art.

[0038] In an embodiment of the present application, an audio transmission method is provided, which is used for the sending object of the audio signal, and the sending object can be a mobile phone, a computer, a headset, a microphone, or other objects that can process audio signals and wirelessly transmit audio signals. The corresponding receiving object of the target audio signal can also be a mobile phone, a computer, a headset, a microphone, or other objects that can receive the wirelessly transmitted target audio signal and obtain the initial audio signal according to the target audio signal.

[0039] Alternatively, if Figure 1 , 2 As shown, the audio transmission method includes:

[0040] S101: acquiring an initial audio signal that meets a preset condition from an audio signal, and processing the initial audio signal based on a first preset method to obtain a target audio signal.

[0041] Optionally, the preset condition includes reaching a threshold value perceived by human ears, and the first preset method includes a preset lossless compression method and a preset error correction method. The initial audio signal that meets the preset condition can be obtained by psychoacoustic modeling (PAM).

[0042] Optionally, the acquired audio signal is a continuous-time audio signal, and acquiring the initial audio signal that meets the preset conditions in the audio signal includes: acquiring a sampling signal of the audio signal, and using a psychoacoustic module to extract the initial audio signal that meets the preset conditions in the sampling signal. Among them, psychoacoustics recognizes how humans perceive sound, emphasizing which frequencies and volume signals the human ear is more sensitive to, and which can be ignored. By quantifying the human ear's non-uniform perception of audio signals, the PAM module can effectively identify and remove frequency bands that the human ear cannot hear or is not sensitive to (i.e., the sound in this frequency band does not meet the preset conditions), thereby greatly reducing the amount of data.

[0043] Optionally, the acquired audio signal is an analog signal, and the sampled signal is a sampled signal obtained by sampling the acquired audio signal based on a preset time interval, wherein the size of the preset time interval corresponding to the sampling operation can be determined according to sampling accuracy, audio playback requirements and other conditions.

[0044] Optionally, the process of extracting the initial audio signal by the psychoacoustic module can be expressed by a formula, wherein the initial audio signal that meets preset conditions in the sampled signal is extracted by using the psychoacoustic module, including: extracting the initial audio signal by using a preset equation corresponding to the psychoacoustic module, the preset equation including: x_p[n]=(x[n]-α*x[n-1]-β*x[n-2])*W(t), wherein x_p[n] is the initial audio signal, α and β are parameters for controlling the masking effect, wherein W(t) is the psychoacoustic weight function, and audio signals of different frequencies have different corresponding psychoacoustic weight functions, and x[n] represents the nth sampled signal.

[0045] In one embodiment, the audio frequency at time t is f, then A is a constant used to adjust the amplitude of the function. The values ​​of ɑ1, β1 and γ correspond to one of f, and the specific values ​​can be determined based on the auditory test data. Among them, in the preset formula, the size of ɑ and β can be adjusted according to the size of the psychoacoustic weight function. Specifically, when the psychoacoustic weight function is less than the preset threshold, α=α1*(1+1 / W(t)+1 / (W(t)*2)), β=β1*(1+1 / W(t)).

[0046] Optionally, the preset lossless compression method includes a lossless compression algorithm, and processing the initial audio signal based on the first preset method includes: compressing the initial audio signal using the lossless compression algorithm based on a preset compression ratio to generate a compressed audio signal.

[0047] In one embodiment, the lossless compression algorithm can compress the initial audio signal into FLAC (Free Lossless Audio Codec), and reduce the amount of audio data transmission by compressing it into this format, while retaining key information of the audio signal to ensure high fidelity of sound quality. The initial audio signal can also be compressed into other formats according to the selected algorithm and format requirements.

[0048] Alternatively, the formula D 压缩 =D 初始 *C represents the amount of data before and after compression. 压缩 Indicates the data volume of the original audio signal obtained after compression, D 初始 represents the data volume of the initial audio signal before compression, and C represents the compression ratio. The compression ratio can be set according to actual needs or the type of compression algorithm used.

[0049] Optionally, the preset error correction method includes an adaptive error correction algorithm, and processing the initial audio signal based on the first preset method further includes: obtaining redundant information corresponding to the compressed audio signal, adding the redundant information to the compressed audio signal, and generating the initial audio signal, wherein the redundant information includes at least one of an error correction code and a checksum. By adding the redundant information to the compressed audio signal, the anti-interference ability of the audio signal during the transmission process is improved, and the reliability of the transmission of the audio signal in a complex environment is improved.

[0050] In one embodiment, the error correction code is a channel code, which can be any one of Hamming code, Hamming code, Bulma, RS code (Reed-Solomon Code), and the error correction code can be generated by any one of automatic request for retransmission, forward error correction, and hybrid error correction. Checksum is an error detection method. By processing the data with a specific algorithm, a short fixed-length check code is generated and attached to the end of the data. The receiver processes the data with the same algorithm and compares it with the attached check code to detect whether the data has errors during transmission. The checksum can be generated by bit-by-bit XOR operation, cyclic redundancy check, etc. Among them, the data volume of the target audio signal = the data volume of the compressed audio signal + the data volume corresponding to the redundant information.

[0051] S102: Wirelessly sending the target audio signal to a receiving object based on the second preset method so that the receiving object obtains an initial audio signal corresponding to the target audio signal and plays the initial audio signal according to the first preset method.

[0052] Optionally, the second preset mode includes a Halow WiFi transmission mode, which is used to expand the coverage of the wireless audio signal and ensure stable transmission in a large space.

[0053] Optionally, a plurality of target audio signal sending modes may be set, and a corresponding sending mode may be selected to send the target audio signal according to at least one of the type of the receiving object, the current communication environment, and the distance between the sending object and the receiving object.

[0054] Optionally, when sending the target audio signal, in order to reduce the probability of data errors, the target audio signal may be divided into multiple groups, and the multiple groups of signals may be sent to the receiving object in sequence.

[0055] Optionally, before sending the target audio signal, an audio signal sending notification may be sent to the receiving object, and if feedback information based on the notification is received from the receiving object, the target audio signal is sent to the receiving object in a second preset manner. If the target audio signal sending notification is not received, the target audio signal will not be sent.

[0056] Optionally, after sending the target audio signal, it is also possible to detect whether a signal reception notification fed back by the receiving object is received within a preset time period. If received, it is determined that the signal generation is completed. If not received, the target audio signal is sent again after the preset time period. The preset time period can be calculated from the moment when the target audio signal is finished being sent.

[0057] Optionally, in order to accurately obtain the initial audio signal, the receiving object processes the received audio signal according to the preset lossless compression method and preset error correction method adopted by the sending object, such as real-time monitoring of the signal reception status, identifying and correcting errors in the received audio signal according to the preset error correction method to ensure data integrity and improve audio quality. The original audio signal is reconstructed from the received compressed data according to the lossless compression algorithm used by the sending object, ensuring that the reconstructed audio signal is consistent with the input signal to achieve distortion-free restoration.

[0058] Optionally, the receiving object may be a speaker, a mobile phone, a computer, or other device that has an audio playback device or can be connected to an audio receiving device. The receiving object may play audio through its own audio playback device or a connected audio playback device, providing the user with a high-quality audio experience. The audio playback device may be a speaker or a headset.

[0059] The audio transmission method of the present application has the following advantages:

[0060] 1. High-quality sound transmission: The use of psychoacoustic modeling and lossless compression algorithm ensures that the audio signal will not lose quality during transmission, thereby obtaining better sound quality.

[0061] 2. Effective bandwidth utilization: Through data compression and the introduction of redundant information, the bandwidth utilization rate is improved (data compression can compress the transmitted data, and more information can be transmitted under the same bandwidth), and more audio information can be transmitted under the same wireless spectrum.

[0062] 3. Intelligent error correction mechanism: Adaptive error correction technology ensures high-quality audio transmission in an interference environment, reducing the risk of data loss and errors.

[0063] 4. Low power consumption design: Halow WiFi technology is designed specifically for IoT devices and has the characteristics of low power consumption, which enables the device to effectively save energy during long-term use and is suitable for wireless audio applications.

[0064] 5. Long-distance transmission capability: It is particularly suitable for long-distance transmission scenarios and can maintain stable audio signal transmission over a large range to meet the needs of modern wireless audio distribution.

[0065] 6. Flexible application scenarios: This technology can be widely used in various scenarios, including home entertainment, smart home, conference system, etc., with good adaptability and scalability.

[0066] 7. Improve user experience: Lossless reconstruction technology ensures that the audio signal received by the user is consistent with the source signal, greatly improving the user's audio experience, especially in high-fidelity music and professional audio applications.

[0067] 8. Anti-interference capability: Redundant transmission mechanism and error correction capability effectively enhance the system's resistance to environmental interference, ensuring reliable operation in complex environments.

[0068] In summary, this technology shows obvious advantages over existing technologies in terms of audio quality, transmission efficiency, system stability and user experience, and has broad application prospects and market value.
