说到“解码器”,相信影音行业人士以及音响发烧友对它并不陌生,解码器是一种将离散型数字信号还原为连续性模拟信号的器材或部件,被广泛地用于影音设备、通讯设备、电脑等与影像,或声音有关的数码电子产品里面。

在我们的影音行业和发烧友里面,对解码器的定义,通常就是指在两声道立体声音响系统里面数模转换器(DAC、Digital to Analog Converter)和家庭影院系统里面的环绕声处理器(Surround Sound Processor)这两种设备。它们都是我们影音系统中几乎必备的器材设备,也是决定声音品质的最关键设备之一,是优美音乐和震撼音效的源泉。

随着时代和科技的发展,保存数字音乐的存储设备不断变化的情况下,解码器无论从支持数字音频规格、性能、功能、输入/输出接口、操作方式以及体积上都出现了很大的变化。正是因为解码器出现变化,使得数字音乐播放系统的组建变得多样化。与此同时,在发展的道路上也出现过很多优秀的代表作品,让不同时期的发烧友津津乐道。

所以,在本期的专题策划中,我们分别以数模转换器和环绕声处理器来展开话题,畅谈一下它们的设计、发展以及应用,为大家解读它们的过去与未来,目的是让大家了解它们的方方面面。
