音乐的音频很宽,一般由10Hz至20KHz。音乐由录制到重放的过程中,损失的中高频信号较多,尤其是信号微弱的高频。这样人们听到重播出来的音乐就不那么动听,有干感。为了解决这一缺陷。80年代初,音响工程师研制了一种名叫“音频激励器”的音响设备。音频激励器不但对原音源进行矫正和修饰,还能够根据原 The music audio is very wide, usually from 10Hz to 20KHz. Music from recording to playback in the process, the loss of more high-frequency signals, especially the signal weak high-frequency. So people hear the replay of the music is not so sweet, dry feeling. In order to solve this defect. In the early 1980s, sound engineers developed a sound device called “Audio Exciter.” Audio stimulator not only the original source correction and modification, but also according to the original
