[0019] The embodiments of the present application include but are not limited to an audio processing method, device, medium and product.

[0020] It is understood that the audio processing method mentioned in the embodiments of the present application can be applied to electronic devices. Among them, the electronic device can be called a terminal, user equipment (UE), mobile terminal (MT), etc. In some specific implementations, the electronic device can be a device with audio playback function, such as a car terminal, a smart phone, a portable music player, a smart watch, and a smart headset.

[0021] The following uses the electronic device as an in-vehicle terminal as an example to introduce the audio processing method mentioned in the embodiment of this application.

[0022] As previously mentioned, when a vehicle is in motion, road noise, wind noise, and other noise can interfere with the sound quality of the vehicle's audio system, thereby reducing the listening experience for users within the vehicle. To address this issue, in some implementations, the volume of the vehicle's audio system can be increased while the vehicle is in motion, thereby increasing the loudness of the audio output by the vehicle's audio system to be louder than the noise. However, if the volume of the vehicle's audio system is already at or near maximum, it cannot be increased further, resulting in poor noise suppression.

[0023] In order to solve the above problems, an embodiment of the present application provides an audio processing method. In this method, during the driving process of the vehicle, the on-board terminal can obtain the real-time speed of the vehicle and the audio being played, and determine the audio segment to be adjusted corresponding to the real-time speed of the vehicle and the adjustment parameters corresponding to each audio segment to be adjusted based on the first corresponding relationship. Among them, the first corresponding relationship is the frequency range of the audio played by the on-board terminal at different speeds affected by noise, and the adjustment parameters corresponding to each frequency range. Thus, the played audio can be adjusted based on the adjustment relationship corresponding to each audio to be adjusted. In this way, by adjusting the audio segment affected by noise in the audio, the noise suppression effect can be improved.

[0024] The following describes in detail the audio processing method mentioned in the embodiment of the present application, taking the scenario of playing audio while a vehicle is driving as an example.

[0025] like Figure 1 FIG. 1 shows a flow chart of an audio processing method. The method can be executed by an electronic device. Specifically, the audio processing method may include:

[0026] S101: Obtain a first speed of a vehicle at a first moment and a first audio to be processed.

[0027] It is understood that the first moment is any moment when the vehicle is in motion and playing audio. In some specific implementations, the electronic device may obtain the real-time speed of the vehicle as the first speed. Furthermore, the electronic device may obtain the audio currently being played by the vehicle as the first audio.

[0028] It is understood that the electronic device may be the vehicle-mounted terminal (also referred to as the vehicle-mounted host) mentioned above. The electronic device may be provided with a dynamic equalizer. In this way, the electronic device can obtain the real-time speed of the vehicle and the currently playing audio, and use the dynamic equalizer to perform noise reduction processing on the currently playing audio.

[0029] It is understood that the electronic device can also be a device connected to the vehicle-mounted terminal mentioned above and having audio processing capabilities. In addition, the electronic device can be provided with a dynamic equalizer. In this way, the electronic device can obtain the real-time speed and currently playing audio transmitted back by the vehicle-mounted terminal.

[0030] S102: Based on the first corresponding relationship, determine N adjustment parameters corresponding to the first speed, where N is a positive integer greater than or equal to 1.

[0031] It can be understood that the first correspondence may include: multiple frequency ranges affected by noise in the audio played by the vehicle at different speeds, and the adjustment parameters corresponding to each frequency range in the multiple frequency ranges. For example, when the vehicle speed is 80km / h, the adjustment parameter corresponding to the frequency range [100Hz, 200Hz] is 10, and the adjustment parameter corresponding to the frequency range [300Hz, 320Hz] is 5; when the vehicle speed is 75km / h, the adjustment parameter corresponding to the frequency range [100Hz, 200Hz] is 9.5; when the vehicle speed is 85km / h, the adjustment parameter corresponding to the frequency range [100Hz, 200Hz] is 10.5. It can be understood that the first correspondence understood above is only an illustration of the embodiment of the present application for the convenience of understanding the scheme listed. In actual application, it can be set according to user needs.

[0032] The following describes how to set up the first correspondence. In actual application, you can first select a vehicle model and conduct a road driving test on the selected vehicle model. During the test, professional audio acquisition equipment and software are used to collect the noise inside the vehicle when the vehicle plays audio at different speeds, and transmit it to the electronic device. Then, the electronic device can analyze how the noise changes with vehicle speed, and select from the noise the frequency range in which the audio intensity significantly increases as the vehicle speed increases. Generally, noise in the low-frequency range increases rapidly as the vehicle speed increases. In this way, the electronic device can use the frequency range corresponding to the noise segment in the low-frequency range as the frequency range affected by the noise. For example, the frequency range [100Hz, 200Hz] mentioned above.

[0033] Specifically, the electronic device can identify a target noise segment from the noise based on the amplitude of the change in audio intensity of the noise over a preset duration, where the amplitude of the change in audio intensity of the target noise segment is greater than a threshold amplitude of change. Furthermore, the electronic device can determine the frequency range corresponding to the target noise segment as the audio range affected by the noise.

[0034] The following describes a method for determining the N adjustment parameters corresponding to the first speed. First, the electronic device can determine, based on the first corresponding relationship, the N frequency ranges to be adjusted corresponding to the first speed, and the adjustment parameters corresponding to each of the N frequency ranges to be adjusted, thereby obtaining N adjustment parameters. For example, based on the first corresponding relationship listed above, when the first speed is 80 km / h, the electronic device can determine the adjustment parameter 10 corresponding to the frequency range [100 Hz, 200 Hz] and the adjustment parameter 5 corresponding to the frequency range [300 Hz, 320 Hz].

[0035] S103: Adjust the audio intensity corresponding to the corresponding frequency range in the first audio according to N adjustment parameters to obtain an adjusted second audio.

[0036] It is understood that in some optional implementations, the electronic device may determine M audio segments to be adjusted from the first audio based on the N frequency ranges to be adjusted, where the M audio segments to be adjusted correspond to the M frequency ranges to be adjusted, and the M frequency ranges to be adjusted are frequency ranges to be adjusted among the N frequency ranges to be adjusted, and M is less than or equal to N. Furthermore, the electronic device may adjust the audio intensities of the M audio segments to be adjusted corresponding to the M frequency ranges to be adjusted in the first audio based on the M adjustment parameters corresponding to the M frequency ranges to be adjusted, to obtain the adjusted second audio.

[0037] like Figure 2 As shown, the electronic device can obtain the first speed of the vehicle at the first moment, and determine the M frequency ranges to be adjusted corresponding to the first speed according to the first corresponding relationship (for example Figure 2 The frequency range to be adjusted 1 to the frequency range to be adjusted M shown in FIG. 1 , and the adjustment parameters corresponding to each of the M frequency ranges to be adjusted (eg Figure 2 Thus, the electronic device can determine M audio segments to be adjusted corresponding to the N frequency ranges to be adjusted from the first audio, and adjust the audio intensities of the corresponding audio segments to be adjusted based on the adjustment parameters corresponding to the M frequency ranges to be adjusted to obtain the second audio.

[0038] In some specific implementations, when the frequency range to be adjusted is a low frequency range, the electronic device may use a low-pass filter as a dynamic equalizer and adjust the cutoff frequency of the low-pass filter to correspond to the frequency range to be adjusted. When the frequency range to be adjusted is a mid-frequency range, the electronic device may use a band-pass filter or a peak filter as a dynamic equalizer.

[0039] For example, assuming that the audio intensity of the audio segment to be adjusted corresponding to the frequency range 1 [100 Hz, 200 Hz] to be adjusted in the first audio is 60 dB, when the electronic device determines that the adjustment parameter corresponding to the frequency range 1 [100 Hz, 200 Hz] to be adjusted in the first audio is 10, the sum of the audio intensity of the audio segment to be adjusted and the adjustment parameter can be used as the adjusted audio intensity of the audio segment to be adjusted, that is, the audio intensity of the audio segment to be adjusted corresponding to the frequency range 1 [100 Hz, 200 Hz] to be adjusted in the second audio is 70 dB.

[0040] It is understood that vehicle speed changes in real time. To reduce the impact of emergency braking or rapid acceleration on vehicle speed, which causes adjustment parameters to change significantly in a short period of time and, in turn, requires significant or continuous adjustment of the audio intensity of the audio segment to be adjusted, thereby introducing noise, the electronic device can perform gain smoothing on the first audio. That is, when the vehicle speed changes significantly, the audio segment to be adjusted in the first audio is adjusted based on the adjustment parameter with a larger change amplitude; when the vehicle speed changes slightly, the audio segment to be adjusted in the first audio is adjusted based on the adjustment parameter with a smaller change amplitude.

[0041] In some methods for gain smoothing the first audio, the electronic device may obtain a second speed of the vehicle at a second moment and, based on a first correspondence, determine Q frequency ranges to be adjusted corresponding to the second speed and an adjustment parameter corresponding to each of the Q frequency ranges to be adjusted, thereby obtaining Q adjustment parameters. Furthermore, the electronic device may determine a parameter difference corresponding to each of the M audio segments to be adjusted from the M adjustment parameters and the Q adjustment parameters, and, based on the relationship between the parameter difference and a parameter difference threshold, select different processing methods to adjust the audio intensity of the frequency segment to be adjusted.

[0042] like Figure 3 As shown, the electronic device can obtain the first speed of the vehicle at the first moment and the second speed at the second moment, and determine the M frequency ranges to be adjusted corresponding to the first speed according to the first corresponding relationship (for example Figure 2 The frequency range to be adjusted 1 to the frequency range to be adjusted M) and the adjustment parameters corresponding to each of the M frequency ranges to be adjusted (for example Figure 2 Furthermore, the electronic device may determine, based on the first corresponding relationship, Q frequency ranges to be adjusted corresponding to the second speed and adjustment parameters corresponding to each of the Q frequency ranges to be adjusted.

[0043] It can be understood that the second moment is earlier than the first moment, and the duration between the second moment and the first moment is less than the duration threshold.

[0044] Furthermore, if Figure 4 As shown, the electronic device can determine the parameter difference corresponding to each of the M audio segments to be adjusted from the M adjustment parameters and the Q adjustment parameters, and determine whether the parameter difference is greater than a parameter difference threshold. If the parameter difference is greater than the parameter difference threshold, a fast gain update can be performed on the first audio to obtain the updated M adjustment parameters. If the parameter difference is less than or equal to the parameter difference threshold, a slow gain update can be performed on the first audio to obtain the updated M adjustment parameters.

[0045] Specifically, if the parameter difference is greater than the parameter difference threshold, the electronic device may adjust the audio intensity of the audio segment to be adjusted corresponding to each frequency range to be adjusted based on the first step size to obtain the second audio. If the parameter difference is less than or equal to the parameter difference threshold, the electronic device may adjust the audio intensity of the audio segment to be adjusted corresponding to each frequency range to be adjusted based on the second step size to obtain the second audio.

[0046] For example, based on the first correspondence relationship listed above, when the first speed is 80 km / h, the electronic device can determine that the adjustment parameter corresponding to the frequency range 1 to be adjusted [100 Hz, 200 Hz] is 10. When the second speed is 75 km / h, the electronic device can determine that the adjustment parameter corresponding to the frequency range 1 to be adjusted [100 Hz, 200 Hz] is 9.5. Assume that the audio intensity of the audio segment to be adjusted corresponding to the frequency range 1 to be adjusted [100 Hz, 200 Hz] in the first audio is 60 dB, the parameter difference threshold is 1, the first step length is 0.1, and the second step length is 0.01. Since the adjustment parameters corresponding to the frequency range 1 to be adjusted are 10 and 9.5, which are smaller than the parameter difference threshold, the electronic device can first adjust the adjustment parameter 10 corresponding to the first speed based on the second step size of 0.01, and adjust the adjustment parameter 9.5 corresponding to the second speed to 9.51, and use the sum of the audio intensity of the audio segment to be adjusted and the updated adjustment parameter as the adjusted audio intensity of the audio segment to be adjusted, that is, the audio intensity of the audio segment to be adjusted corresponding to the frequency range 1 [100Hz, 200Hz] to be adjusted in the second audio is 69.51dB.

[0047] Next, combine Figure 5 Introduce the structure of the vehicle. Figure 5 A structural schematic diagram of a vehicle provided in an embodiment of the present application is shown.

[0048] Figure 5 This is a possible functional framework diagram of a vehicle provided in an embodiment of the present application. Figure 5 As shown, the functional framework of the vehicle may include various subsystems, such as the sensor system 10, the control system 20, one or more peripheral devices 30 (one is shown as an example), a power supply 40, and a computer system 50. Optionally, the vehicle may also include other functional systems, such as an engine system that provides power to the vehicle, etc., which are not limited in this application.

[0049] The sensor system 10 may include several detection devices that can sense the information being measured and convert the sensed information into electrical signals or other required forms of information output according to certain rules. Figure 5As shown, these detection devices may include a global positioning system 11 (GPS), a vehicle speed sensor 12 , an inertial measurement unit 13 (IMU), etc., which is not limited in this application.

[0050] The Global Positioning System (GPS) 11 utilizes GPS positioning satellites for real-time positioning and navigation worldwide. In the present application, the GPS 11 can be used to achieve real-time positioning of a vehicle and provide information about the vehicle's geographic location. The vehicle speed sensor 12 is used to detect the vehicle's speed. The inertial measurement unit (IMU) 13, which may include a combination of an accelerometer and a gyroscope, is a device for measuring the vehicle's angular velocity and acceleration. For example, while the vehicle is in motion, the IMU can measure changes in the vehicle's position and angle based on the vehicle's inertial acceleration, such as the vehicle's acceleration and angular velocity.

For example, the user performs touch operations on the content data displayed on the touch screen 32 according to actual needs to implement the function corresponding to the touch operation, such as playing multimedia files such as music and videos. The user interface 33 can specifically be a touch panel for detecting operating instructions on the touch panel. The user interface 33 can also be a physical button or a mouse. The user interface 33 can also be a display screen for outputting data, displaying images or data. Optionally, the user interface 33 can also be at least one device belonging to the category of peripheral devices, such as a touch screen, a microphone, and a speaker.

[0055] Several functions of the vehicle are controlled and implemented by a computer system 50. The computer system 50 may include multiple processors, such as a processor 51, a CDC 52, an MDC 53, and a T-BOX 54, as well as a memory 55 (also referred to as a storage device) and a gateway 56. In actual applications, the memory 55 is also internal to the computer system 50, or it can be external to the computer system 50, for example, as a cache in the vehicle, etc. This application is not limited to this.

The processor 51, CDC 52, MDC 53, and T-BOX 54 may be configured to execute related programs or instructions corresponding to the programs stored in the memory 55 to implement corresponding vehicle functions, such as network switching on a service-by-service basis.

[0057] The T-BOX 54 may include a first storage unit 200 and a communication unit 210. The first storage unit 200 may be an embedded multimedia card, and the capacity of the first storage unit 200 may be a standard specification of 4GB, 8GB, 16GB or 32GB.

The communication unit 210 may include radio frequency front-end (RFFE) 211, filter 212, modem 213 and power amplifier 214 and other radio frequency components. The radio frequency front-end 211, filter 212, modem 213 and power amplifier 214 and other radio frequency components may be integrated on a radio frequency integrated circuit (RFIC). The communication unit 210 may also include a central processing unit (CPU) 220 and a second storage unit 230. The second storage unit 230 can store calibration parameters of radio frequency components such as the radio frequency front-end (RFFE) 211 , the filter 212 , the modem 213 , and the power amplifier 214 .

[0058] The memory 55 may include volatile memory, such as RAM; the memory may also include non-volatile memory, such as ROM, flash memory, HDD or solid-state drive (SSD); the memory 55 may also include a combination of the above types of memory. The memory 55 can be used to store a set of program codes or instructions corresponding to the program codes, so that the processor 51 can call the program codes or instructions stored in the memory 55 to implement the corresponding functions of the vehicle.
