Abstract
Description
Technical Field
[0001] This application relates to the field of intelligent driving technology, and in particular to an audio fidelity adjustment method, device, computer equipment, and storage medium. Background Technology
[0002] Frequency modulation (FM) distortion is a common problem in modern intelligent driving, especially in the application of automatic volume and audio control technologies. FM distortion typically occurs during the transmission or processing of audio signals. Changes in the waveform, frequency, or amplitude of the audio signal during transmission or processing lead to a reduction in the quality of the audio output compared to the original input, altered timbre, or the introduction of noise. Generally, FM distortion has several causes: First, if the gain of the audio signal is adjusted too high, the peak value of the signal will exceed the maximum level of the speaker or amplifier, causing clipping, which can result in distortion or noise. Second, if the equalizer of the audio equipment over-adjusts a certain frequency band, such as excessively boosting low or high frequencies, it will also lead to unnatural audio effects and distortion. Furthermore, errors in digital signal processing can also cause audio signal distortion, such as poor algorithm design, numerical approximations, and improper rounding. Proper audio processing, equalization, and gain control are crucial to ensure optimal audio output and avoid FM distortion. Summary of the Invention

[0022] Please see Figure 6 , Figure 6 This diagram illustrates an application scenario of the audio fidelity adjustment method provided in an embodiment of this application. The audio fidelity adjustment method is applied to… Figure 6 Among the 500 computer devices.
[0023] Figure 1 This is a flowchart illustrating the audio fidelity adjustment method provided in an embodiment of this application. Figure 1 As shown, the method includes the following steps S110-S160.
[0024] S110. Based on the obtained input volume value and maximum volume value, calculate the available gain space value of the audio signal corresponding to the input volume value.
[0025] Specifically, 1. Input volume: This refers to the input level of the audio signal, usually expressed in decibels (dB), and is the relative intensity of the sound. The higher the input volume, the louder the sound. 2. Maximum volume: This refers to the maximum level that the audio device can handle, also usually expressed in decibels. Exceeding the maximum volume will lead to distortion and noise problems. In this context, the available gain margin can be defined as the maximum volume minus the input volume. The specific calculation formula is as follows: Available gain margin = Maximum volume - Input volume. For example, if the maximum volume of an audio device is 100dB and the current input volume is 80dB, then the available gain margin is: Available gain margin = 100dB - 80dB = 20dB. This means that the gain of the audio signal can be adjusted to a maximum range of 20dB without causing distortion or noise problems.
[0026] S120. The obtained balance setting value is summed with the available gain space value to obtain the alternative gain space value.
[0027] Specifically, the obtained balance setting value is summed with the available gain margin value to obtain the alternative gain margin value. The specific calculation formula is as follows: Alternative gain margin value = Balance setting value + Available gain margin value. Here, the balance setting value refers to the volume adjustment made by the user to different frequency bands according to actual needs, usually expressed in decibels. The larger the balance setting value, the louder the volume of that frequency band. For example, if a user sets a +3dB balance in the low-frequency band, and the available gain margin of the audio device is 20dB, then the alternative gain margin value is: Alternative gain margin value = 3dB + 20dB = 23dB. This means that the volume of that frequency band can be increased by 23dB without causing distortion or noise problems.
[0028] S130. Summing the current speaker volume value with the alternative gain space value yields the current gain space value.
[0029] S140. Determine whether the current gain space value meets the preset gain judgment condition.
[0030] S150. If the gain judgment condition is met, the current gain space value is determined as the actual gain value of the audio signal corresponding to the input volume value.
[0031] S160: Calculate the predicted volume value based on the actual gain value and the input volume value to adjust the actual volume.
[0032] Specifically, the current speaker volume value is summed with the candidate gain space value to obtain the current gain space value. Current gain space value = Current speaker volume value + Candidate gain space value. It is then determined whether the current gain space value meets a preset gain judgment condition. The gain judgment condition can be a threshold or range set according to specific needs. If the current gain space value meets the gain judgment condition, proceed to the next step. If the current gain space value does not meet the gain judgment condition, appropriate adjustments are needed, such as lowering the balance setting or the current speaker volume value, and then recalculating the current gain space value. The current gain space value is determined to be the actual gain value of the audio signal corresponding to the input volume value. The current gain space value is the actual gain value. Based on the actual gain value and the input volume value, a predicted volume value is calculated, which is used to adjust the actual volume. Predicted volume value = Input volume value + Actual gain value.
[0033] In summary, when a user adjusts audio functions such as volume, balance, bass, and treble, the gain space is calculated based on the user-set volume value. The gain space is adjusted based on the user-set balance value and the speaker volume setting. The maximum gain value (Eq_Max) of the EQ is calculated based on the EQ setting, and the actual gain value (EqGain) of the EQ is adjusted according to its relationship with the gain space. Finally, the gain value of the internal DSP module is calculated based on the preceding gain data. This process is primarily used to calculate and adjust the gain values of various audio functions based on the user's audio settings. By converting the user-set volume, balance, speaker volume, and EQ settings into gain spaces and adjusting them according to certain rules, the final gain value can be obtained to control the attenuation or enhancement of the audio signal. Technically, this process provides precise gain adjustment based on the user's audio settings. By converting the settings of different audio functions into gain spaces and calculating and adjusting them according to established rules, fine-grained control of the audio signal can be achieved. This ensures that the audio output meets the user's needs and provides a better listening experience. Furthermore, by comparing the gain range and EQ settings, issues such as excessive gain or distortion can be avoided, ensuring the stability and accuracy of audio quality. Precise gain adjustment based on the user's audio settings provides a better audio experience and prevents audio quality problems.
[0034] like Figure 2 As shown, in a more specific embodiment of this solution, step S140 further includes steps S141-S142:
[0035] S141. Determine the maximum gain space value of the corresponding audio signal based on the current equalization setting value of the gain judgment condition.
[0036] Specifically, the gain determination conditions include:
[0037] S142. Determine whether the current gain space value is not greater than the maximum gain space value, so as to determine whether the current gain space value meets the gain judgment condition.
[0038] If the current gain space value is not greater than the maximum gain space value, then the current gain space value is determined to meet the gain judgment condition.
[0039] Specifically, the gain determination condition includes the following two steps:
[0040] S141: Determine the maximum gain space value of the corresponding audio signal based on the current equalization setting value of the gain judgment condition.
[0041] S142: Determine whether the current gain space value is not greater than the maximum gain space value, so as to determine whether the current gain space value meets the gain judgment condition.
[0042] In S141, the maximum gain space value of the corresponding audio signal can be determined based on the current equalization setting value of the gain judgment condition. The specific calculation method involves the characteristics of the audio signal, the range of equalization settings, and the algorithm, and needs to be determined according to the specific situation. In S142, by comparing the current gain space value with the maximum gain space value, it can be determined whether the current gain space value meets the gain judgment condition. If the current gain space value is not greater than the maximum gain space value, then it can be determined that the current gain space value meets the gain judgment condition.
[0043] like Figure 3 As shown, in a more specific embodiment of this solution, before executing step S130, step S131 must also be executed:
[0044] S131. Determine whether the maximum gain space value is greater than zero.
[0045] Specifically, if the maximum gain space value is not greater than zero, then the current gain space value is set to zero;
[0046] If the maximum gain space value is greater than zero, then proceed to step S142.
[0047] In another, more specific embodiment of this solution, step S132 must be performed before step S130:
[0048] S132. Determine if the current speaker volume is less than zero.
[0049] If the current speaker volume value is not less than zero, then proceed to step S130.
[0050] If the current speaker volume value is less than zero, the current speaker volume value is retrieved again to calculate the current gain space value.
[0051] Specifically, before executing step S130, either step S131 or step S132 needs to be executed first. Specifically, step S131 determines whether the maximum gain space value is greater than zero. If it is not greater than zero, the current gain space value is set to zero; if it is greater than zero, step S142 continues. Step S132, based on step S131, additionally determines whether the current speaker volume value is less than zero. If it is less than zero, the current speaker volume value is re-acquired to calculate the current gain space value. In step S131, the maximum gain space value is first determined to be greater than zero. If it is not greater than zero, it means that gain adjustment cannot be performed, so the current gain space value is set to zero. This avoids the gain space value exceeding a reasonable range, leading to sound distortion or other problems. If the maximum gain space value is greater than zero, step S142 continues to be executed to determine and adjust the gain space value. In step S142, the maximum gain space value of the corresponding audio signal is determined based on the current equalization setting value, and it is determined whether the current gain space value meets the gain judgment condition. If the conditions are met, step S130 is executed to adjust the gain; if not, adjustments or other processing are performed according to the specific situation. In step S132, it is additionally determined whether the current speaker volume value is less than zero. If it is less than zero, it indicates that the speaker has a fault or abnormality, and the current speaker volume value needs to be re-acquired to calculate the current gain space value. This ensures that the calculated gain space value accurately reflects the current speaker status, avoiding inaccurate gain adjustment or other problems caused by abnormal speaker status.
[0052] like Figure 4 As shown, in another more specific embodiment of this solution, steps S121-122 must be performed before step S120:
[0053] S121. Obtain the preset tuning optimization value.
[0054] S122. Determine whether the sum of the preset tuning optimization value and the input volume value is greater than the available gain space value of the audio signal corresponding to the input volume value.
[0055] If the sum of the preset tuning optimization value and the input volume value is greater than the available gain space value of the audio signal corresponding to the input volume value, then the balance setting value is set to zero, and step S120 is executed.
[0056] Specifically, before executing step S120, steps S121 and S122 need to be executed first. Specifically, step S121 is used to obtain a preset tuning optimization value, while step S122 is used to determine whether the sum of the preset tuning optimization value and the input volume value is greater than the available gain space value of the audio signal corresponding to the input volume value. If it is greater, the balance setting value is set to zero. To ensure the reasonableness of the tuning optimization value and volume value, and to avoid sound distortion or other problems caused by excessively high tuning optimization values, in step S121, a preset tuning optimization value is first obtained. This value can be preset according to system requirements and user preferences, and is used to adjust the balance of the audio signal or other sound effect parameters. In step S122, the preset tuning optimization value is compared with the sum of the input volume value. If it is greater than the available gain space value of the audio signal corresponding to the input volume value, it indicates that the tuning optimization value is too high, which will lead to exceeding the available gain range. To avoid sound distortion or other problems, the balance setting value is set to zero, i.e., balance adjustment is canceled.
[0057] The actual adjustment process is as follows: 1. Master Volume Adjustment: Controlled using the Fader Volume module, with maximum volume set to 0dB and minimum volume set to -79dB. 2. Fader / Balance Function Adjustment: Controlled using the Fader Volume module, ranging from 0dB to -79dB. 3. Speaker Level Function Adjustment: Also controlled using the Fader Volume module, ranging from 10dB to -24dB. 4. EQ Function Adjustment: Achieved by simultaneously adjusting the Dvol (Att), EQ, Dvol (Boost), and Fader Volume modules. The EQ module's adjustable range is -12dB to +12dB, the Dvol (Att) module's adjustable range is 0dB to -95dB, and the Dvol (Boost) module's adjustable range is 0dB to 36dB. Generally, the audio signal, after processing by the Dvol (Att), EQ, Dvol (Boost), and Fader Volume modules, is finally output to the power amplifier. To avoid sound distortion, the DSP output signal should not exceed 0dB, as this will cause distortion. Therefore, this solution uses an algorithm to balance various functional modules, preventing excessive gain that could lead to sound distortion. By appropriately adjusting the gain values of modules such as Dvol (Att), EQ, Dvol (Boost), and Fader Volume, the audio signal can be attenuated or amplified within an appropriate range to achieve the user's desired volume and sound quality. Simultaneously, this adjustment ensures the stability and accuracy of the audio output, providing a better listening experience. By controlling the internal functional modules of the DSP and considering their adjustment ranges and characteristics, combined with algorithmic gain balancing, precise adjustment of the audio signal can be achieved, preventing sound distortion and providing excellent sound quality.
