以前对AC′97声卡的印象是:不值钱,只配做附赠品的AC′97软声卡,甚至痛恨主板厂家添加这种无用组件增加成本,可是实际的情况究竟如何呢? AC′97全称Audio Codec′97(简称AC′97,意为“音效多媒体数字信号编/解码器”)是Intel、Creative Labs、NS、Analog Device与Yamaha共同制定的音频电路系统标准,现在大部分声卡都遵循AC′97标准,包括主流的Creative Sound Blaster Live!和Audigy。所谓AC′97软声卡,就是用CPU模拟硬声卡的主处理芯片的功能进行各种数字处理,将数字信号处理后交由外置DAC或者板载Codec输出。
AC’97 sound card before the impression is: worthless, only with accessories AC’97 soft sound card, or even hate the motherboard manufacturers to add such useless components to increase costs, but the actual situation how? AC’97 full name Audio Codec’97 (referred to as AC’97, meaning “audio multimedia signal encoder / decoder”) is a standard audio circuit system jointly developed by Intel, Creative Labs, NS, Analog Device and Yamaha, and now most of the sound cards follow AC ’ 97 standards, including the mainstream Creative Sound Blaster Live! And Audigy. The so-called AC’97 soft sound card, is to use the CPU simulation hard sound card’s main processing chip features a variety of digital processing, the digital signal processing by external DAC or on-board Codec output.
