一种自适应音频控制方法 An audio control method for adaptively

技术领域 Technical Field

[0001] 本发明涉及家用电器,尤其涉及一种自适应音频控制方法。 [0001] The present invention relates to household appliances, particularly, to a method for adaptive audio control.

背景技术 Background technique

[0002] 在音频领域中,听到的最多的一个词,恐怕就要数声道了。 [0002] In the audio field, one of the most heard word, I am afraid the number of channels necessary. 的确,但从声卡或者音箱来看,都可以按它分成2.1声道、5.1声道以及7.1声道等,可见它的重要性。 Indeed, a sound card or speakers but from the point of view, you can press it into 2.1 channel, 5.1 channel and 7.1 channel, etc., we can see its importance.

[0003] 所谓声道,是指声音在录制或播放时在不同空间位置采集或回放的相互独立的音频信号。 [0003] The so-called channel refers to the sound recording or playback position to acquire at different spatial or playback of audio signals independently of each other. 而我们平时所说的声道数也就是声音录制时的音源数量或回放时相应的扬声器数量。 And we usually say is the number of channels corresponding to the number of speakers when playing back audio volume or sound recording.

[0004] 几十年以前,声音都是从一只扬声器中重放出来的,这就是单声道放声。 [0004] Several decades ago, the sound is reproduced from a speaker out, which is mono burst. 可以说,它是一种非常原始的声音复制形式。 I can say that it is a very primitive form of sound reproduction. 显然这与音乐厅里现场演奏的声音有很大的差别。 Obviously, this is very different from the music hall live performance sound. 在音乐厅里聆听音乐,可辨别乐器声音的方向和音乐厅的混响效果,单声道相当于一个点声源,当然无法重放这些效果,所以它的“现场感”受到很大限制。 In the music hall listening to music, musical reverb discernible direction and concert sound, mono sound source is equivalent to a point, of course, these effects can not be reproduced, so it's "live feel" is very restricted. 由于单声道缺乏对声音的位置定位,所以其声音的效果不够真实。 Due to the lack of a position fix mono sound, so the sound is not true effect. 而直到立体声技术的出现,才彻底改变了这一状况。 And until stereo technology was completely changed the situation. 在这种技术下,声音在录制过程中被分配到两个独立的声道,从而达到了很好的声音定位效果。 In this technique, the voice in the recording process was assigned to two independent channels, so as to achieve a good sound positioning effect. 这种技术在音乐欣赏中显得尤为有用,听众可以清晰地分辨出各种乐器来自的方向,从而使音乐更富想象力,更加接近于临场感受。 This technique is particularly useful for music appreciation, the audience can be clearly distinguished from the direction of a variety of musical instruments, making music more imaginative, feel closer to the spot.

[0005] 随着立体声的兴起,最先出现的当数双声道。 [0005] With the rise of the stereo, first appeared when the number of dual-channel. 它由左、右两组拾音器录音,两个声道存储和传送,两组扬声器放音,所以也称为2— 2— 2系统。 It playback from left and right two pickup recording, storage and transfer of two channels, two sets of speakers, it is also known as the 2-2-2 system.

[0006] 人们的欲望是无止境的,立体声虽然满足了人们对左右声道位置感体验的要求,但是随着技术的进一步发展,大家逐渐发现双声道已经越来越不能满足我们的需求。 [0006] people's desires are endless, although the stereo left and right channels to meet people experience a sense of requirements of the position, but with the further development of technology, we gradually discovered two channels has become increasingly unable to meet our needs. 此时,又诞生了一种新的声音效果一三维音效。 At this time, and the birth of a new sound effect a three-dimensional sound. 而要达到好的效果,仅仅依靠两个音箱是远远不够的,所以立体声技术在三维音效面前就显得捉襟见肘了,但四声道环绕音频技术则很好的解决了这一问题(这里所说的四声道,在实际使用时却是5声道既4.1声道)。 To achieve good results, relying solely on the two speakers is not enough, so three-dimensional sound stereo technology before it is stretched, but the four-channel surround audio technology is a good solution to this problem (mentioned here The four-channel, in actual use Shique both 4.1-channel 5-channel).

[0007] 四声道环绕规定了4个发音点:前左、前右,后左、后右,听众则被包围在这中间。 [0007] Four-channel surround provides four pronunciation points: front left, front right, rear left, rear right, the audience were surrounded in the middle. 同时还建议增加一个低音音箱,以加强对低频信号的回放处理(这也就是当年4.1声道音箱系统广泛流行的原因)。 It also proposed to add a subwoofer to enhance the low-frequency signal playback processing (which is then widely popular 4.1-channel speaker system reasons).

[0008] 就整体效果而言,四声道系统可以为听众带来来自多个不同方向的声音环绕,可以获得身临各种不同环境的听觉感受,给用户以全新的体验。 [0008] On the whole effect is concerned, quadraphonic sound system can bring to the audience from many different directions surround, you can achieve the same auditory experience a variety of different environments, giving users a whole new experience. 不过,四声道的音箱产品现在已经不很多了。 However, four-channel speaker is now not a lot. 取而代之的,便是它的所谓改进版本一5.1声道音箱。 Instead, it is an improved version of a so-called 5.1-channel speakers.

[0009] 在5.1的基础上7.1系统又增加了中左和中右两个发音点,以求达到更加完美的境界。 [0009] 5.1, based on the 7.1 system adds the left and right in two pronunciation points, in order to achieve a more perfect world.

[0010] 这些音频系统对用户的位置有要求,只有在用户处于预定的位置时,才能够得到最大的音乐效果,现有的音频系统一般不能根据用户的位置来调整不同声道的音频信号。 [0010] The audio system to the user's location is required, only when the user is in a predetermined position to be able to get the maximum musical effect, existing audio systems are generally not to adjust the audio signals of different channels according to the user's location.

[0011] 专利“音频系统及音频处理方法”(申请号:201210120285.3申请日:2012-04-23)公开了一种音频系统及音频处理方法。 [0011] Patent "audio system and audio processing method" (application number: 201210120285.3 filing date: 2012-04-23) discloses a method for the audio system and audio processing. 此音频系统包括中央处理单元、数字信号处理器及编码解码器。 The audio system includes a central processing unit, digital signal processor and the codec. 其中,数字信号处理器是连接中央处理单元,用以辅助中央处理单元处理音频信号。 Wherein the digital signal processor is connected to a central processing unit, a central processing unit for processing the auxiliary audio signals. 编码解码器是连接数字信号处理器,用以辅助中央处理单元处理声音文件的编码及解码。 A codec is connected to a digital signal processor for encoding and decoding auxiliary central processing unit of sound files. 数字信号处理器是接收中央处理单元输出的信号处理需求,据以导通中央处理单元与编码解码器之间的数据传输通道,以传输数据。 A digital signal processor is a central processing unit receiving an output signal processing requirements, according to the data transmission channel is turned on and the central processing unit between the codec to transmit data.

[0012] 该专利一方面不能根据用户的位置来调整不同声道的音频信号,另一方面,音频系统的开关均需要手动控制,非常不方便。 [0012] The patent on the one hand can not be adjusted according to the user's location audio signals of different channels, on the other hand, the audio system switches require manual control, very inconvenient.
