[0047] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0048] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0049] Existing technical solutions usually adopt a fixed allocation method, that is, predetermine which processing tasks the vehicle machine node and the power amplifier node are responsible for, and transmit and process audio signals accordingly. This method has the following disadvantages:

[0050] On the one hand, the fixed allocation method cannot adapt to different audio signal types and processing requirements, which may lead to waste or insufficient computing resources of the vehicle-mounted node or the power amplifier node. For example, for some audio signal types that require more computing resources, if the vehicle-mounted node is responsible for most of the processing tasks, it may cause the vehicle-mounted node to be overloaded or unable to complete other functions; if the power amplifier node is responsible for most of the processing tasks, it may cause the power amplifier node to be overloaded or unable to complete other functions.

[0051] On the other hand, the fixed allocation method cannot adapt to different types and performances of vehicle head unit nodes and power amplifier nodes, which may lead to poor compatibility and scalability of the vehicle audio system. For example, the computing power of vehicle head unit nodes or power amplifier nodes of different models or versions may vary. If the audio signal is transmitted and processed according to the fixed allocation method, some nodes may not work properly or perform better.

[0052] Therefore, there is still room for improvement in the existing technical solutions.

[0053] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0054] The audio processing method provided by this application is intended to solve the above technical problems of the prior art. The audio processing method can be applied to Figure 1 A schematic diagram of the architecture of a vehicle audio system is shown in FIG. Figure 1 As shown, the vehicle audio system includes:

[0055] The vehicle computer node is used to receive and process the audio code stream, including encoding, decoding, rendering and other operations on the audio code stream.

[0056] The power amplifier node is used to receive the processed audio code stream distributed by the vehicle node and perform further processing. The above further processing includes but is not limited to at least one of the following: spatial audio decoding, multi-channel rendering, post-processing and other operations on the audio code stream.

[0057] The transmission bus is used to connect the vehicle computer node and the power amplifier node, and transmit the audio code stream and other related data based on the audio transmission protocol. The above-mentioned bus has the characteristics of low latency and high reliability; among which, the above-mentioned audio transmission protocol is used to specify the format and transmission method of the audio code stream and other related data.

[0058] Optionally, the vehicle computer node in the vehicle audio processing system is a device for receiving, processing and transmitting audio signals, and the power amplifier node is a device for amplifying and outputting audio signals.

[0059] After receiving the audio processing task, the vehicle computer node first sends a query request to the power amplifier node, and the power amplifier node returns a response message to the query request, so that the vehicle computer node determines the computing power of the power amplifier node according to the response message. Then, the above-mentioned vehicle computer node can allocate the audio code stream to be processed in the above-mentioned audio processing task to the above-mentioned vehicle computer node and / or the above-mentioned power amplifier node according to the computing power of the above-mentioned power amplifier node and the computing power of the above-mentioned vehicle computer node, as well as the task amount of the above-mentioned audio processing task, so as to use the above-mentioned vehicle computer node and / or the above-mentioned power amplifier node to process the above-mentioned audio code stream, and transmit the processed audio code stream to the array for playing using at least one speaker.

[0060] In the embodiment of the present application, the processing task of the audio code stream can be dynamically allocated according to the computing power of the vehicle machine node and the power amplifier node and the task amount of the audio processing task, so as to realize efficient processing of the audio signal. Then, the processed audio data is output to the speaker array on the power amplifier node to be played using at least one speaker.

[0061] In addition, on the transmission bus between the vehicle computer node and the power amplifier node, an audio transmission protocol is used to specify the format and transmission method of the audio code stream and other related data, thereby realizing the effective distribution and reception of audio data.

[0062] On the one hand, the embodiments of the present application can adapt to different audio signal types and processing requirements, avoiding waste or insufficient computing resources of the vehicle machine node or the power amplifier node. For example, for some audio signal types that require more computing resources, most of the processing tasks can be assigned to nodes with stronger computing power, thereby improving processing speed and quality; for some audio signal types that require less computing resources, most of the processing tasks can be assigned to nodes with weaker computing power, thereby saving computing resources and electricity.

[0063] On the other hand, the embodiments of the present application can adapt to different types and performances of vehicle-mounted machine nodes and power amplifier nodes, and improve the compatibility and scalability of the vehicle-mounted audio system. For example, for vehicle-mounted machine nodes or power amplifier nodes of different models or versions, processing tasks can be allocated according to their actual computing capabilities, so that they can work normally or exert their better performance; for power amplifier nodes whose computing capabilities change at any time, the vehicle-mounted machine node can obtain its computing capability information through query request and response messages, and adjust the allocation scheme of audio processing tasks accordingly, so that it can quickly perform audio processing.

[0064] In addition, the above-mentioned vehicle audio system may also include, but is not limited to, one or more processing modules:

[0065] The thread optimization module is used to achieve low-latency and high-reliability data transmission between the vehicle computer node and the power amplifier node. The above-mentioned thread optimization module optimizes data transmission by dynamically adjusting the number and priority of threads.

[0066] In the embodiment of the present application, a thread optimization module is set in the vehicle audio system to achieve low-latency and high-reliability data transmission between the vehicle computer node and the power amplifier node, and data transmission is optimized by dynamically adjusting the number and priority of threads, thereby achieving fast transmission and synchronization of audio data and improving the transmission efficiency and reliability of audio data.

[0067] The cache optimization module is used to realize efficient storage and reading of data between the vehicle computer node and the power amplifier node. The cache optimization module realizes the optimization of data storage and reading by dynamically adjusting the cache size and position.

[0068] In the embodiment of the present application, a cache optimization module is set in the vehicle audio system, and the cache size and position are dynamically adjusted to optimize data storage and reading, so that efficient storage and reading of audio data can be achieved, and the memory usage and reading time of audio data are reduced.

[0069] The cross-layer call optimization module is used to realize the rapid conversion and processing of data between the vehicle computer node and the power amplifier node. The above-mentioned cross-layer call optimization module realizes the optimization of data conversion and processing by dynamically adjusting the format and interface of the data.

[0070] In the embodiment of the present application, a cross-layer call optimization module is set in the vehicle audio system, and data conversion and processing are optimized by dynamically adjusting the data format and interface between the vehicle computer node and the power amplifier node, thereby realizing rapid conversion and processing of audio data.

[0071] The spatial audio production module is used to realize three-dimensional spatial processing of audio data on the vehicle machine node or the power amplifier node. The above-mentioned spatial audio production module realizes the spatialization of audio data by adding metadata to the audio data.

[0072] In the embodiment of the present application, by setting up a spatial audio production module in the in-vehicle audio system, native support for three-dimensional spatial audio can be achieved, the immersion and interactivity of the audio data are improved, the spatial processing of the audio data is realized, and the spatial sense and positioning sense of the audio data are improved.

[0073] The intelligent tuning module is used to implement post-processing of audio data on the vehicle computer node or the power amplifier node. The above-mentioned intelligent tuning module implements post-processing of audio data by analyzing and adjusting the audio data.

[0074] In the embodiments of the present application, by setting up an intelligent tuning module in the vehicle audio system, post-processing of audio data can be achieved, thereby improving the balance and adaptability of the audio data; different forms of processing of audio data can be achieved, thereby improving the diversity and compatibility of audio data.

[0075] The present application also provides an embodiment of an audio processing method. Figure 2 is a flowchart of an audio processing method provided by an embodiment of the present application, such as Figure 2 As shown, the method includes:

[0076] S201, a vehicle machine node in a vehicle audio processing system sends a query request to a power amplifier node in the vehicle audio processing system in response to a received audio processing task.

[0077] S202, the vehicle computer node determines the computing capacity of the power amplifier node according to the response message returned by the power amplifier node in response to the above query request.

[0078] S203, the vehicle computer node distributes the audio code stream to be processed in the above audio processing task to the above vehicle computer node and / or the above power amplifier node according to the computing power of the power amplifier node and the computing power of the vehicle computer node, as well as the task amount of the audio processing task, so as to use the above vehicle computer node and / or the above power amplifier node to process the above audio code stream, and transmit the processed audio code stream to at least one speaker for playback.

[0079] Optionally, the vehicle computer node in the vehicle audio processing system is a device for receiving, processing and transmitting audio signals, and the power amplifier node is a device for amplifying and outputting audio signals.

[0080] After receiving the audio processing task, the vehicle computer node first sends a query request to the power amplifier node, and the power amplifier node returns a response message to the query request, so that the vehicle computer node determines the computing power of the power amplifier node according to the response message. Then, the above-mentioned vehicle computer node can allocate the audio code stream to be processed in the above-mentioned audio processing task to the above-mentioned vehicle computer node and / or the above-mentioned power amplifier node according to the computing power of the above-mentioned power amplifier node and the computing power of the above-mentioned vehicle computer node, as well as the task amount of the above-mentioned audio processing task, so as to use the above-mentioned vehicle computer node and / or the above-mentioned power amplifier node to process the above-mentioned audio code stream, and transmit the processed audio code stream to at least one speaker for playback.

[0081] The embodiment of the present application can dynamically allocate the processing tasks of the audio code stream according to the computing power of the vehicle machine node and the power amplifier node and the task volume of the audio processing task, thereby realizing efficient processing of the audio signal. Afterwards, the processed audio data is output to the speaker for playback on the power amplifier node.

[0082] Optionally, an audio transmission protocol is used on the transmission bus between the vehicle computer node and the power amplifier node to specify the format and transmission method of the audio code stream and other related data, thereby realizing the effective distribution and reception of audio data.

[0083] For example, in the embodiment of the present application, for certain audio signal types that require more computing resources, most of the processing tasks can be assigned to nodes with stronger computing capabilities, thereby improving processing speed and quality; for certain audio signal types that require fewer computing resources, the method can assign most of the processing tasks to nodes with weaker computing capabilities, thereby saving computing resources and power. Therefore, the embodiment of the present application can adapt to different audio signal types and processing requirements, avoiding waste or insufficient computing resources of vehicle-mounted nodes or power amplifier nodes.

[0084] For another example, in an embodiment of the present application, for vehicle computer nodes or power amplifier nodes of different models or versions, processing tasks can be allocated according to their actual computing capabilities, so that they can work normally or exert their better performance; for power amplifier nodes whose computing capabilities change at any time, the vehicle computer node can obtain their computing power information through query request and response messages, and adjust the task allocation plan accordingly, so that it can quickly perform audio processing.

[0085] Therefore, the embodiments of the present application can adapt to the types and performances of different vehicle-mounted computer nodes and power amplifier nodes, and improve the compatibility and scalability of the vehicle-mounted audio system.

[0086] The audio processing method embodiment provided by the present application adopts a vehicle-mounted audio processing system node in response to a received audio processing task to send a query request to a power amplifier node in the vehicle-mounted audio processing system; then, the computing power of the power amplifier node is determined according to a response message returned by the power amplifier node for the query request; finally, according to the computing power of the power amplifier node and the computing power of the vehicle-mounted node, as well as the task amount of the audio processing task, the audio code stream to be processed in the audio processing task is allocated to the vehicle-mounted node and / or the power amplifier node, so that the audio code stream is processed by the vehicle-mounted node and / or the power amplifier node, and the processed audio code stream is transmitted to at least one speaker for playback.

[0087] Therefore, the embodiments of the present application can solve the problem that the prior art cannot reasonably allocate the computing tasks of the vehicle computer node and the power amplifier node, resulting in the inability to efficiently process audio signals, and can achieve the technical effect of adapting to different audio signal types and processing requirements and avoiding waste or insufficient computing resources of the vehicle computer node or the power amplifier node.

[0088] In an optional implementation, Figure 3 is a flowchart of an audio processing method provided by an embodiment of the present application, such as Figure 3 As shown, the vehicle computer node determines the computing capacity of the power amplifier node according to the response message returned by the power amplifier node in response to the query request, including:

[0089] S301, the vehicle machine node obtains at least one of the following node information carried in the above response message: model information, computing power information, memory information, and software version information;

[0090] S302, the vehicle computer node queries the computing capacity of the power amplifier node corresponding to the node information in a predetermined computing capacity configuration table.

[0091] Optionally, the computing power configuration table may be a pre-recorded "power amplifier model - computing power (such as 800mips, 1200mips, etc.)" relationship configuration table. Optionally, the computing power configuration table may be stored locally in the vehicle system or in a cloud server and retrieved when in use.

[0092] In one example, the above-mentioned vehicle computer node can send a query request or query-type information to the power amplifier node through a transmission bus based on an audio transmission protocol. After receiving the query request, the power amplifier node sends a response message to the vehicle computer node, and informs the vehicle computer node of model information, computing power information, memory information, software version information and other information. The vehicle computer node queries the computing power configuration table based on the above information to obtain the computing power of the power amplifier node.

[0093] Since the car computer node knows its own computing power and the total amount of tasks, after knowing the computing power of the power amplifier node, the car computer node can reasonably arrange and allocate the processing methods of the audio processing tasks. If it is determined that the car computer node needs to process a part of the task, the data after the partially processed task is completed will be sent to the power amplifier node.

[0094] Optionally, an embodiment of the present application provides a specific method for determining the computing power of an amplifier node, which is achieved by obtaining node information such as model information, computing power information, memory information, software version information, etc. of the amplifier node carried in a response message, and querying the corresponding computing power in a predetermined computing power configuration table.

[0095] In one example, for certain models or versions of power amplifier nodes, their computing power may not match their appearance or specification parameters. If their computing power is estimated only based on their appearance or specification parameters, it may lead to an over- or under-estimated value, thereby affecting the effect of task allocation. Therefore, by using the above query method provided by the present application, the computing power of the power amplifier node can be accurately obtained, avoiding unreasonable or unbalanced task allocation caused by estimation errors in computing power.

[0096] In another example, for some models or versions of amplifier nodes, their computing power may be difficult to obtain through simple testing or measurement. If the vehicle-mounted computer node is required to perform complex testing or measurement on them, it may lead to a waste of time and resources, thereby affecting the processing efficiency of the audio signal. Therefore, the above-mentioned query method provided by the present application can simplify the work of the vehicle-mounted computer node and avoid the waste of time and resources caused by testing or measuring the computing power of the amplifier node.

[0097] In an optional implementation, Figure 4 is a flowchart of an audio processing method provided by an embodiment of the present application, such as Figure 4As shown, the vehicle computer node determines the computing capacity of the power amplifier node according to the response message returned by the power amplifier node in response to the query request, including:

[0098] S401, the vehicle-machine node obtains the computing power information carried in the above response message.

[0099] S402, the vehicle computer node determines the computing power of the power amplifier node according to the computing power information.

[0100] Optionally, an embodiment of the present application provides another specific method for determining the computing power of the power amplifier node, which obtains the computing power information carried in the response message and determines the computing power of the power amplifier node based on this. Specifically, instead of using the computing power configuration table, after receiving the query request, the power amplifier node directly sends the computing power information of the power amplifier node to the vehicle-mounted node, so that the vehicle-mounted node can directly determine the computing power of the power amplifier node based on the received computing power information.

[0101] In one example, for some models or versions of amplifier nodes, their node information may be incomplete or inaccurate. If the computing power is obtained based on the node information alone, it may lead to acquisition failure or error. Therefore, directly feeding back the computing power information of the amplifier node to the vehicle computer node can directly obtain the computing power of the amplifier node, avoiding the failure or error in obtaining the computing power due to the lack or inaccuracy of the node information.

[0102] In another example, for example, the type and performance of a newly added or replaced power amplifier node may not match the existing computing power configuration table. If the computing power configuration table needs to be updated or maintained, it may cause increased workload or delays. Therefore, directly feeding back the computing power information of the power amplifier node to the vehicle computer node can flexibly adapt to power amplifier nodes of different types and performances, avoiding increased workload or delays caused by updating or maintaining the computing power configuration table.

[0103] In an optional implementation manner, the vehicle machine node sends a query request to the power amplifier node in the vehicle audio processing system, including:

[0104] S501, the vehicle computer node determines an audio transmission protocol supported by both the vehicle computer node and the power amplifier node;

[0105] S502, the vehicle computer node sends a query request to the power amplifier node based on the audio transmission protocol.

[0106] In an embodiment of the present application, a specific method for sending a query request is provided. The method obtains an audio transmission protocol supported by both the vehicle computer node and the power amplifier node, and sends a query request to the power amplifier node based on the audio transmission protocol on the transmission bus.

[0107] In one example, since the audio transmission protocols supported by certain types or versions of vehicle-mounted nodes or amplifier nodes may be different, if the matching of the audio transmission protocols is not considered, the query request may not be successfully sent or received. Therefore, the above method can ensure the successful sending and receiving of the query request and avoid communication failures or errors caused by mismatching of the audio transmission protocols.

[0108] In another example, for certain types or versions of vehicle-mounted nodes or amplifier nodes, the audio transmission protocols they support may have advantages and disadvantages. If the suitability of the audio transmission protocol is not considered, the query request may be transmitted slowly or of poor quality. Therefore, the above method can improve the transmission efficiency and quality of the query request and avoid communication delays or distortions caused by inappropriate audio transmission protocols.

[0109] In an optional implementation manner, the vehicle machine node distributes the audio code stream to be processed in the audio processing task to the vehicle machine node and / or the power amplifier node, including:

[0110] S601, the vehicle computer node determines an audio transmission protocol supported by both the vehicle computer node and the power amplifier node.

[0111] S602, based on the above-mentioned audio transmission protocol, the vehicle computer node transmits the audio code stream processed or unprocessed by the above-mentioned vehicle computer node to the above-mentioned power amplifier node, so that the above-mentioned power amplifier node processes the received audio code stream to obtain the above-mentioned processed audio code stream, or directly transmits the audio code stream processed by the above-mentioned vehicle computer node as the above-mentioned processed audio code stream to the above-mentioned speaker.

[0112] In one example, for certain types or versions of vehicle-mounted nodes or amplifier nodes, the supported audio transmission protocols may be different. If the compatibility of the audio transmission protocols is not considered, the audio code stream may not be successfully transmitted or received.

[0113] In the embodiment of the present application, by obtaining the audio transmission protocol supported by both the vehicle machine node and the power amplifier node, and based on this, transmitting the audio code stream to be processed or the processed audio code stream, the successful transmission and reception of the audio code stream can be guaranteed, and communication failure or error caused by mismatch of the audio transmission protocol can be avoided. In addition, the transmission efficiency and quality of the query request can be improved, and communication delay or distortion caused by inappropriate audio transmission protocol can be avoided.

[0114] In an optional implementation manner, the above method further includes:

[0115] The vehicle computer node dynamically adjusts the audio code streams to be processed allocated to the vehicle computer node and the power amplifier node according to the computing power of the power amplifier node and the computing power of the vehicle computer node, as well as the task volume of the audio processing task.

[0116] In an embodiment of the present application, audio processing tasks can be dynamically adjusted and switched. For example, in the first second, the vehicle-mounted computer node is used to perform one operation, such as decoding processing, and the power amplifier node is used to perform two operations, such as rendering and post-processing. In the second second, it can be switched to using the vehicle-mounted computer node to perform two operations. After the decoding operation is completed, rendering processing is required, and the power amplifier node is used to perform one post-processing operation.

[0117] By dynamically adjusting the audio code streams to be processed allocated to the car-machine node and the power amplifier node according to the computing power of the power amplifier node and the car-machine node and the task volume of the audio processing task, it is possible to adapt to the changes in computing resources and task requirements at different time points, and avoid the waste or shortage of computing resources caused by fixed task allocation schemes. For example, for audio processing tasks that require more computing resources at certain time points, this method can allocate more audio code streams to be processed to nodes with stronger computing power, thereby improving processing speed and quality; for audio processing tasks that require fewer computing resources at certain time points, this method can allocate fewer audio code streams to be processed to nodes with weaker computing power, thereby saving computing resources and electricity.

[0118] On the other hand, the above-mentioned dynamic adjustment processing method can improve the flexibility and adaptability of the task allocation scheme, and avoid unreasonable or unbalanced task allocation caused by a fixed task allocation scheme. For example, for abnormal situations that occur at certain time points, such as failure, freeze, restart, etc. of the vehicle machine node or the power amplifier node, this method can adjust the task allocation scheme in time according to the actual situation, thereby ensuring the normal processing of the audio signal.

[0119] In an optional implementation manner, the audio code stream is processed by the vehicle machine node and / or the power amplifier node, including:

[0120] S701, using the above-mentioned vehicle machine node and / or the above-mentioned power amplifier node to decode the above-mentioned audio code stream to obtain a decoded audio code stream.

[0121] S702: Use the vehicle computer node and / or the power amplifier node to render the decoded audio code stream to obtain a rendered audio code stream.

[0122] S703: Post-process the rendered audio code stream using the vehicle machine node and / or the power amplifier node to obtain a post-processed audio code stream.

[0123] Optionally, in an embodiment of the present application, the above-mentioned post-processing may include but is not limited to: noise reduction processing, which can improve the purity and clarity of the audio by removing noise, such as electrical noise, background noise, etc.; equalization processing, which can make the sound quality of the audio more balanced by adjusting the volume of different frequency bands in the audio; compression processing, which can make the volume of the audio more stable by adjusting the dynamic range of the audio to avoid excessive or insufficient volume differences; reverberation processing, which can make the audio sound more natural, three-dimensional, and have depth by adding reverberation effects; editing processing, which can remove unnecessary parts by editing the audio to make the audio more compact and smooth; synthesis processing, which can make the audio more complete and coherent by synthesizing multiple audio files into one.

[0124] An embodiment of the present application also provides a specific method for processing an audio code stream, which decodes, renders and post-processes the audio code stream by adopting a spatial audio decoding algorithm, a spatial audio rendering algorithm and a spatial audio post-processing algorithm.

[0125] In one example, for some audio signal types that need to have a sense of space and stereo, such as surround sound, 3D sound, etc., this method can restore its original spatial information and effects through a spatial audio decoding algorithm, a spatial audio rendering algorithm, and a spatial audio post-processing algorithm. This method can improve the sense of space and stereo of the audio signal and avoid the bland or monotonous sound quality caused by ordinary audio decoding algorithms, ordinary audio rendering algorithms, and ordinary audio post-processing algorithms.

[0126] In another example, this method can improve the adaptability and compatibility of audio signals and avoid sound quality differences or distortion caused by different types or versions of vehicle-mounted nodes or power amplifier nodes. For example, for different types or versions of vehicle-mounted nodes or power amplifier nodes, the spatial audio decoding algorithms, spatial audio rendering algorithms, and spatial audio post-processing algorithms they support may be different. If these differences are not taken into account, it may lead to sound quality differences or distortion. The consistency and compatibility between the nodes can be ensured by adopting a unified spatial audio decoding algorithm, spatial audio rendering algorithm, and spatial audio post-processing algorithm.
