欣赏高保真的立体声音乐是一种享受。立体声的重放效果是单声道所无法比拟的。但是目前的调幅广播、电视伴音及一些调频广播台均为单声道播放,一些老式收、放音设备也属单声道系统。为了充分利用这些设备和提高单声道广播的接收效果,可以将单声道信号进行处理,使之分割成具有一定时间差、相位差和强度差的模拟立体声信号,然后,再通过立体声放音设备进行重放,使我们也能从老式单声道设备中体会到立体声的魅力。
Enjoy hi-fi stereo music is a pleasure. Stereo playback is unmatched by mono. However, the current AM broadcasts, TV sound recordings and some FM radio stations are all played in mono mode. Some old-style receiving and playback devices are also mono systems. In order to make full use of these devices and improve the receiving effect of monaural broadcasting, the mono signal can be processed to be divided into analog stereo signals with a certain time difference, phase difference and intensity difference, and then, through a stereo playback device Replay, so that we can also experience the charm of stereo from the old mono equipment.
