Stereophonic
简而言之，立体声是一种旨在通过声音的宽度和深度来模拟人耳自然听觉的声音记录和重放的方式。通过两个话筒（以及起着补充作用的辅助话筒），两个独立的声音信号分别被记录到两个通道上。同民用音响一样，电子声学音乐也广泛地采用了立体声。立体声可以通过任意数量扬声器的系统重放，并适合扩散声场和自由声场等诸多环境。这个词源于希腊语的stereos，意为“坚固的”，可见立体声所追求的是一种接近自然听觉的的效果。
Usually abbreviated to stereo, a form of sound recording and reproduction which aims to reproduce a spatial aural experience, in terms of width and depth, analogous to human binaural hearing. Two microphones (plus possible additional complementary microphones) are used to record two independent representations of sound to two channels. As well as representing a domestic audio standard, stereo has been widely adopted in electroacoustic music, stereo being suited to playback over any number of loudspeakers, and therefore used in diffusion systems, octophonic systems and so on. The term is derived from the Greek stereos, meaning solid, which is the aural effect it strives to achieve.
