一个新鲜词出现得多了,也就变得时髦了,到处都用。“数字”就是这样一个词,“数字生活”、“数字时代”、“数字地球”,还有“数字经济”、“数字健康”、“数字家庭”什么什么的。出现多了,就不新鲜了,挂在嘴边随便说,究竟是什么内容、什么涵义,反倒不清楚了。所以,我们在讲“数字音频”的时候,必须把数字音频的常见格式梳理一下,心中有个概念。 A new word appears much, it becomes fashionable, everywhere. “Number” is the term “digital life,” “digital age,” “digital earth,” and what is “digital economy,” “digital health,” and “digital home.” Appear more, it is not fresh, hanging around and said casually, what is the content, what meaning, but do not know. Therefore, when we talk about “digital audio”, we must sort out the common format of digital audio and have a concept in mind.
