[0040] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.
[0041] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
[0042] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The embodiments will be described in detail below in conjunction with the accompanying drawings.
[0043] The vehicle includes an in-vehicle panoramic sound system, which is equipped with multiple speakers, including front speakers, rear speakers, center speakers, ceiling speakers, etc., to create multiple sources of sound, aiming to provide a more immersive audio experience for passengers in the car.
[0044] However, the vocals in the in-car surround sound usually only occur through the center speaker, which will cause the vocals to be small for the rear passengers. If the vocals are mixed to the left and right channels and tuned together with the audio signals of the left and right channels, this will cause the overall sound field to be narrow after tuning.
[0045] Specifically, in order to solve the problems of the prior art, the embodiments of the present application provide an audio processing method, device, equipment, storage medium and vehicle. The audio processing method provided by the embodiments of the present application is first introduced below.
[0046] Figure 1 A schematic flow chart of an audio processing method provided by an embodiment of the present application is shown. The method comprises the following steps:
[0047] S110, obtaining a first audio signal to be played in a first speaker of a vehicle, wherein the first speaker is a center speaker in the vehicle, and the first audio signal is a human voice signal.
[0048] In this embodiment, the first audio signal refers to a sound signal generated by human vocal cords, which may be a human voice in a movie or song. The first audio signal is usually played by a center speaker in a vehicle. Before the center speaker plays the first audio signal, the first audio signal may be acquired by an audio processor in the vehicle.
[0049] S120: Perform a tuning operation on the first audio signal.
[0050] In this embodiment, after the audio processor obtains the first audio signal, a tuning operation can be performed on the first audio signal. The tuning operation may include one or more of equalization processing, compression processing, delay processing, adding reverberation effects, and adding distortion effects to the first audio signal to ensure the quality of the first audio signal when it is played.
[0051] S130: Mix the first audio signal and the second audio signal to obtain a third audio signal, wherein the second audio signal includes at least one of a left channel audio signal and a right channel audio signal.
[0052] In this embodiment, the second audio signal includes a left channel audio signal and a right channel audio signal, that is, an environmental sound signal or a background sound signal other than the human voice signal to be played in the left channel and the right channel. After the first audio signal is tuned, the tuned first audio signal and the second audio signal can be mixed together to synthesize a third audio signal.
[0053] Specifically, during the synthesis process, the volume of each audio signal can be adjusted, and audio effects such as equalization, reverberation, distortion, chorus, etc. can be added to change the sound quality or sound effect of the sound, and then all audio signals are mixed together to generate a single mixed output, that is, the third audio signal.
[0054] S140: Send the third audio signal to a second speaker, so that the second speaker plays the third audio signal.
[0055] In this embodiment, the second speaker is a left channel speaker installed on the left side of the vehicle and a right channel speaker installed on the right side of the vehicle, other than the center speaker in the vehicle. After the first audio signal and the second audio signal are mixed to obtain a third audio signal, the third audio signal can be sent to the second speaker, and the second speaker plays the third audio signal.
[0056] Since the third audio signal also includes a human voice signal, the second speaker and the first speaker will cooperate to play the human voice signal to improve the clarity of the human voice signal.
[0057] In the present application, by obtaining the first audio signal to be played in the first speaker of the vehicle, wherein the first speaker is the center speaker in the vehicle, and the first audio signal is a human voice signal; performing a tuning operation on the first audio signal; mixing the first audio signal and the second audio signal to obtain a third audio signal, wherein the second audio signal includes at least one of a left channel audio signal and a right channel audio signal; sending the third audio signal to the second speaker so that the second speaker plays the third audio signal. In this way, the human voice signal that was originally played only in the center player can be tuned first, and then mixed with the left channel audio signal and / or the right channel audio signal to obtain the third audio signal, and the third audio signal can be played in the second speaker. In this way, the human voice signal will not affect the sound field width of the original second audio signal, and the human voice signal can be played almost simultaneously from the first speaker and the second speaker, thereby enhancing the clarity of the human voice signal.
[0058] As an optional embodiment, the performing a tuning operation on the first audio signal includes:
[0059] performing equalization processing on the first audio signal;
[0060] Performing delay processing on the first audio signal after equalization processing;
[0061] The amplitude of the first audio signal after delay processing is adjusted.
[0062] In this embodiment, after the audio processor acquires the first audio signal, it may first perform equalization processing on the first audio signal, that is, adjust the sound quality of the first audio signal by adjusting the volume of different frequency ranges in the first audio signal.
[0063] After the equalization process, a time delay may be introduced, the position and timing of the first audio signal may be adjusted, and the amplitude of the first audio signal may be adjusted to adjust the playback volume of the human voice.
[0064] By tuning the first audio signal, the quality of the human voice signal can be ensured, and when the human voice signal is played through each speaker, multiple speakers are played in coordination to enhance the user's hearing effect and clarity.
[0065] As an optional embodiment, performing delay processing on the first audio signal after equalization processing includes:
[0066] Obtaining a location area where the user in the vehicle is located;
[0067] Determine the sound range corresponding to the position area;
[0068] The first audio signal is subjected to delay processing, wherein a delay duration of the delay processing is associated with a relative position of the sound zone and the second speaker.
[0069] In this embodiment, the position of the user in the vehicle can be determined by a camera installed in the vehicle, and then the sound zone corresponding to the position can be determined. For each speaker in the vehicle, the time required for the sound played by it to propagate to different sound zones is different. After determining the sound zone where the user is located, the first audio signal can be delayed according to the position of the sound zone to adjust the playback timing of each speaker playing the first audio signal, so as to control the human voice signals played by each speaker to reach the user's ears at the same time.
[0070] As an optional embodiment, the delay processing of the first audio signal includes:
[0071] Acquire a first distance from the first speaker to a midpoint of the sound range;
[0072] Obtaining a second distance from the second speaker to the midpoint of the sound range;
[0073] The first audio signal is delayed according to the delay time, wherein the delay time is determined by the first distance and the second distance.
[0074] In this embodiment, after determining the sound zone where the user is located, a first distance from the first speaker to the midpoint of the sound zone can be determined, and the first distance can be approximately considered as the distance from the sound output by the first speaker to the user's ears; similarly, the second distance can be approximately considered as the distance from the sound output by the second speaker to the user's ears.
[0075] If the second distance is greater than the first distance, the first audio signal can be delayed and then mixed with the second audio signal to obtain a third audio signal. Then the first speaker will play the first audio signal first, and then the second speaker will play the third audio signal. In this way, the human voice in the first audio signal and the human voice in the third audio signal will reach the user's ears almost at the same time, ensuring that the user can hear the human voice clearly.
[0076] As an optional embodiment, before performing delay processing on the first audio signal according to the delay duration, the method further includes:
[0077] determining a first quotient of the second distance divided by a speed of sound, and a second quotient of the first distance divided by the speed of sound, the speed of sound being a speed at which sound propagates in air;
[0078] A first difference value of the first quotient minus the second quotient value is determined as the delay duration corresponding to the second speaker.
[0079] In this embodiment, after obtaining the second distance from the second speaker to the midpoint of the sound zone and the first distance from the first speaker to the midpoint of the sound zone, a first quotient value can be calculated with the second distance as the dividend and the sound speed as the divisor. The first quotient value is the first time required for the audio signal to propagate from the first speaker to the user's ear. Similarly, a second quotient value is calculated with the first distance as the dividend and the sound speed as the divisor. The second quotient value is the second time required for the audio signal to propagate from the second speaker to the user's ear.
[0080] Then, if the first speaker and the second speaker play the human voice signal at the same time, the first difference between the first quotient and the second quotient is the time interval between when the user hears the human voice signals emitted by the two speakers. Therefore, the time interval can be directly used as the delay time of the first audio signal. After the delay, the user can hear the audio signals played in the two speakers at the same time. Through the above delay processing, the clarity of the human voice signal perceived by the user can be guaranteed.
[0081] As an optional embodiment, the door speaker is installed in a door of the vehicle.
[0082] In this embodiment, the second speaker may be a door speaker installed in a door of the vehicle. As an optional embodiment, there are two second speakers, one installed at the bottom of the door panel of the left rear door, and the other installed at the bottom of the door panel of the right rear door. For each second speaker, the first audio signal may be tuned and mixed once to generate a corresponding third audio signal. This ensures that the speakers are used in conjunction to provide a clear human voice signal to the user.
