立体声上变换5.1环绕声的原理

Principle of Stereo Transformation on 5.1 Surround Sound

除了最基本的方向、响度、音调和音色以外,人耳的听觉还包括反映声音空间特性的因素,即双耳对周围环境产生的一种综合的整体印象,包括临场感、空间感和温暖感等。不断增加声音重放系统的声道数,也就是为了能够将这些信息尽可能多的予以实现。

In addition to the basic direction, loudness, pitch and timbre, the auditory factors include the sound spatial characteristics, which is an overall impression that ears generate in response to the surrounding environment, including telepresence, the sense of space and warmth. Increasing the number of channels in sound reproducing system is to produce those effects as much as possible.
