Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

The singular forms “a,” “said,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms, and “multiple” generally includes at least two unless the context clearly indicates otherwise.
[0037] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.
[0038] It should be understood that although the terms first, second, third, etc., may be used in the embodiments of this application, these descriptions should not be limited to these terms. These terms are only used to distinguish the descriptions. For example, first may also be referred to as second without departing from the scope of the embodiments of this application, and similarly, second may also be referred to as first.

[0041] It should be noted that any symbols and / or numbers present in the specification that are not marked in the accompanying drawings are not reference numerals.
[0042] As mentioned in the background technology, current technologies ensure that the gain changes of a single audio gain module are not too abrupt and reduce pops by adding fade-in and fade-out processing to the gain of a single audio gain module. However, when multiple audio gain modules change simultaneously, current technologies cannot perform multi-module control according to the actual situation, and there is still a risk that the speaker will not respond properly and pops will occur.
[0043] Taking vehicles as an example, the inventors, after careful research, discovered that the reason for the aforementioned technical problems lies in:
[0044] Current automotive audio signal transmission systems commonly include a loudness compensation module. This module consists of several filters, each with a gain linked to the in-vehicle volume index. Externally, this means the gain increases as the volume decreases from high to low, and decreases as the volume increases from low to high. Additionally, the transmission system includes a gain module linked to the in-vehicle volume index, with the module gain decreasing sequentially from maximum to minimum volume.
[0045] When the volume index changes, both modules change simultaneously. If the overall gain effect undergoes a large abrupt change during this process, a pop will occur. For example: at t0, the volume index (corresponding to the pre-adjustment volume index below) is 30, the volume module gain (corresponding to the volume control gain item below) is 0, and the loudness compensation gain (corresponding to the loudness compensation gain item below) is 0; at t1, the volume index (corresponding to the post-adjustment volume index below) is 7, the volume module gain is -20dB, and the loudness compensation gain is 8dB. If both modules receive the index signal simultaneously and their gains change simultaneously, but the volume module gain changes slower than the loudness compensation module gain, then at the instant of t1, the gain of the loudness compensation module at the filter will be greater than the gain at t0. This instantaneous gain change will cause the speaker to fail to respond properly, resulting in a pop.
[0046] Similarly, at t0, the volume index is -7, the volume module gain is -20, and the loudness compensation gain is 8; at t1, the volume index is 30, the volume module gain is 0dB, and the loudness compensation gain is 0dB. If both modules receive the index signal simultaneously and their gains change simultaneously, the volume module gain changes faster than the loudness compensation module gain, and the loudness compensation module gain does not drop to 0. This will cause an additional increase in gain at the loudness compensation module filter at the instant of t1. This instantaneous gain change will also cause the speaker to fail to respond properly, resulting in a pop.
[0047] To address the aforementioned technical problems, the present invention proposes the following solutions:
[0048] Figure 1 This is a flowchart of an audio signal link control method provided by an embodiment of the present invention. This embodiment is applicable to at least any audio playback device (e.g., a car audio system) audio control scenario. The audio signal link control method can be, but is not limited to, executed by the audio signal link control device in this embodiment as the execution subject, which can be implemented in software and / or hardware. Figure 1 As shown, the audio signal link control method includes at least the following steps:
[0049] S1. In response to the user's volume adjustment action, at least the pre-adjustment volume index, the post-adjustment volume index, and at least one pair of follow-up gain terms corresponding to the volume adjustment action are determined.
[0050] The pre-adjustment volume index refers to the volume index of the audio playback device before the user performs the volume adjustment action, while the post-adjustment volume index refers to the volume index of the audio playback device after the user performs the volume adjustment action.
[0051] It is understandable that the adjustable gain term can be composed of two interconnected audio control gain terms (for "interconnected" as explained above: current automotive audio signal links generally include a loudness compensation module, which consists of several filters. The gain of each filter is linked by the in-vehicle volume index, and externally, the gain increases as the volume decreases from high to low and decreases as the volume increases from low to high. At the same time, there is also a gain module linked by the in-vehicle volume index in the link, and the module gain decreases sequentially from the maximum to the minimum volume), such as a volume control gain term and a loudness compensation gain term.
[0052] S2. Determine the index increment / decrement status based on the pre-adjustment volume index and the post-adjustment volume index.
[0053] There are two states for index addition and subtraction.
[0054] In one specific implementation, optionally, when the adjusted volume index is greater than the original volume index, the index increment / decrement state is determined to be an index increment state; when the adjusted volume index is less than the original volume index, the index increment / decrement state is determined to be an index decrement state.
[0055] S3. Determine the state priority gain term and state lag gain term in each pair of adjustable gain terms based on the index increment / decrement status.
[0056] Among them, the state priority gain term can refer to the gain term whose centering gain decreases before and after the volume index changes; adaptively, the state lag gain term can refer to the gain term whose centering gain increases before and after the volume index changes.
[0057] In another specific implementation, optionally, the state priority gain term is at least a volume control gain term; and the state lag gain term is at least a loudness compensation gain term.
[0058] In another specific implementation, optionally, the state priority gain term is at least a loudness compensation gain term; and the state lag gain term is at least a volume control gain term.
[0059] S4. The gain item is activated according to the adjusted volume index control state priority, and after a preset time delay, the gain item is activated according to the adjusted volume index control state lag.
[0060] The preset delay can be adaptively configured according to the actual application conditions, and its size and precision are not limited by this invention.
[0061] For example, Figure 4 This is a schematic diagram illustrating the application architecture of an audio signal link control method provided by an embodiment of the present invention in a vehicle. (See attached diagram.) Figure 4 After the user adjusts the volume on the vehicle's infotainment system, the system sends the current volume index A (the aforementioned post-adjustment volume index) and the previous volume index B (the aforementioned pre-adjustment volume index). The system then compares these indices to determine C (the aforementioned index increment / decrement state). If C > 0, index A is first sent to the loudness compensation module (the state-priority gain term in the index increment state), and then after a delay of t, it is sent to the volume module (the state-lag gain term in the index increment state). If C < 0, index A is first sent to the volume module (the state-priority gain term in the index decrement state), and then after a delay of t, it is sent to the loudness compensation module (the state-lag gain term in the index decrement state).
[0062] Furthermore, a scenario embodiment is provided below to support the aforementioned technical solution.
[0063] Table 1 is the volume curve table, and Table 2 is the loudness compensation table.

[0068] Referring to Tables 1 and 2, at time t0, the volume index is 16, the volume module gain is -16, and the loudness compensation gain is 0. At time t1, the volume index is 7, the volume module gain is -37dB, and the loudness compensation gain is 8dB. At this time, C = 7 - 16 = -9 < 0, the volume control module takes effect first, changing from -16 to -37. After time t, the loudness compensation gain changes from 0 to 8.
[0069] The technical solution provided in this embodiment firstly determines, in response to the user's volume adjustment action, at least a pre-adjustment volume index, a post-adjustment volume index, and at least one pair of follow-up gain terms corresponding to the volume adjustment action; further, it determines the index increment / decrement state based on the pre-adjustment volume index and the post-adjustment volume index; further, it determines the state priority gain term and the state lag gain term in each pair of follow-up gain terms based on the index increment / decrement state; finally, it controls the state priority gain term to take effect based on the post-adjustment volume index, and after a preset time delay, continues to control the state lag gain term to take effect based on the post-adjustment volume index. Therefore, this embodiment can at least dynamically set the processing order of any pair of follow-up gain terms by determining the direction of volume adjustment, ensuring that when changing from high volume to low volume, volume is adjusted before EQ, and when changing from low volume to high volume, EQ is adjusted before volume, thereby effectively suppressing pops caused by parameter changes in the audio signal link, which helps improve the smoothness of audio playback and user experience.
[0070] It should be noted that, by precisely controlling the order in which the control modules take effect, this embodiment of the invention can fundamentally avoid transient impacts caused by the mismatch between signal amplitude and filter gain in audio playback devices. Simultaneously, by automatically identifying whether the volume is increasing or decreasing, it requires no user intervention and exhibits a high degree of intelligence. Furthermore, this control logic can be deployed at the software DSP layer or as part of a hardware state machine, making it suitable for various embedded audio devices.
[0071] Figure 2 This is a schematic diagram of an audio signal link control device provided in an embodiment of the present invention. This embodiment is applicable to at least any audio control scenario of an audio playback device. The audio signal link control device can be implemented in software and / or hardware. Figure 2 As shown, the audio signal link control device includes at least:

[0073] The status determination module 120 is used to determine the index increment / decrement status based on the pre-adjustment volume index and the post-adjustment volume index.
[0074] The gain term determination module 130 is used to determine the state priority gain term and the state lag gain term in each set of adjustable gain term pairs based on the index increment / decrement status.
[0075] The activation control module 140 is used to activate the priority gain item according to the adjusted volume index control state, and after a preset time delay, to activate the lag gain item according to the adjusted volume index control state.

[0080] Optionally, the status determination module 120 is specifically used for:
[0081] When the adjusted volume index is greater than the original volume index, the index increment / decrement state is determined to be the index increment state.
[0082] When the adjusted volume index is less than the original volume index, the index increment / decrement state is determined to be the index decrement state.
[0083] The technical solution provided in this embodiment firstly, in response to the user's volume adjustment action, determines at least the pre-adjustment volume index, the post-adjustment volume index, and at least one pair of follow-up gain terms corresponding to the volume adjustment action through the parameter determination module; further, the state determination module determines the index increment / decrement state based on the pre-adjustment volume index and the post-adjustment volume index; further, the gain term determination module determines the state priority gain term and the state lag gain term in each pair of follow-up gain terms based on the index increment / decrement state; finally, the activation control module controls the state priority gain term to take effect based on the post-adjustment volume index, and after a preset time delay, continues to control the state lag gain term to take effect based on the post-adjustment volume index. Therefore, this embodiment can at least dynamically set the processing order of any pair of follow-up gain terms by judging the direction of volume adjustment, ensuring that when changing from high volume to low volume, volume is adjusted before EQ, and when changing from low volume to high volume, EQ is adjusted before volume, thereby effectively suppressing pops caused by parameter abrupt changes in the audio signal link, which helps improve the smoothness of audio playback and user experience.
