As we have seen from the above definition of the AC 97 sound card, it represents only an audio processing technology, an abstract specification, not a specific sound card product category. I would like to clarify here that many friends treat the AC 97 sound card with the soft sound card, or confuse the AC 97 sound card with the motherboard integrated sound card, in fact these are not correct. Now on the market of multimedia sound card, in addition to CMI8738, and so on a few exceptions, mostly follow the AC 97 standard, including the famous innovation Sound Blaster live! series sound card. AC 97 is a technical specification, in short, it employs a dual-chip architecture that allows ADC and DAC to remain relatively independent as far as possible, in order to reduce interference and improve sound quality. This is by Intel, analog devices and other related manufacturers to develop the audio circuit system standards, and has been widely recognized by the industry. Very interesting article, perhaps I can install this advanced-driver for the codec on my D1215!ĪC 97 is all called "Audio Codec 97", meaning "audio multimedia digital Signal codec".
