下面是音频系列的第2部分由Windows景色酣然的队程序管理员理查Fricks，第一个是理查的片断 使用话筒列阵提高酣然的捕获. 这篇第二代产品文章细节如何使更多脱离您的个人计算机通过使用一个数字式话筒。

数字式话筒是完善的适合为窗口景色的话筒列阵技术。 数字式话筒多年来，但近来，能力集成这样技术每天便携式计算机以一个付得起的价格没有。 我是否是否是提及了他们难以置信地紧凑的？ 这底部口岸Akustica数字式话筒的图片：

Akustica AKU2000

这是高质量，容易地集成膝上计算机个人计算机的有效的数字式话筒的一个了不起的例子。

有担保提及这个特殊话筒的某些独特的特征。 首先， Akustica有给他们合并整个设计硅一块唯一芯片的一个独特的制造过程。 这个整体设计在一块芯片一起安置传感器、话筒电路、放大器和交换器全部。 这是提供重大好处模式话筒并且其他数字式话筒要求多块芯片的一个了不起的进步。 明确表达的其中一最容易的好处是它的优越免疫到RF干涉。

比较目的，细听以下音频夹子。 这些夹子使用被装备的同一台膝上计算机被做了

The following post comes from my colleague Steve Ball, Senior Program Manager for Sound in Windows Vista, and continues his team's on-going series on how Windows Vista treats various forms of audio.

Part I: Why does my Windows sound sometimes "glitch?"

Windows is a rich and complex OS designed for multi-tasking users whose tasks must share access to scarce system hardware and resources. Unfortunately, despite multiple decades of incredible advances in PC and CPU architectures, there are non-trivial, complex interactions between applications, processes, and devices in even the most advanced personal computers that make a supposedly "easy" task -- like playing back music without occasional glitches -- much more difficult than it may seem at first glance.

Another way of thinking about this: it seems odd that a modern >$2000 PC may sometimes have trouble seamlessly playing back music when $20 CD players can effortlessly playback music without glitches.

So why do many $2000 PCs occasionally glitch while playing back music? The quick answer is this: Windows is not a single-function device like a CD player.

A slightly longer answer goes like this: even an average Windows machine today is commonly used simultaneously as a media player, word processor, presentation projector, spreadsheet number cruncher, authoring tool, photo editor, media server, video recorder, music composition tool, communications device, search engine, virus detector, data compressor and decompressor, and backup manager. And these are only a few of the possible tasks and processes that are run at the same time on

Below is a post from my colleague Richard Fricks, a Program Manager on the Windows Vista Audio team, discussing Windows Vista's treatment of microphone arrays when used to capture audio. If this entry prompts questions, let me know via the Comments section below and I'll pass them along to Richard.

Providing a solid audio capture experience is not a simple task. It requires a holistic approach that takes into consideration the entire life-time of the audio signal. A weakness at any one point in the path can result in a degraded signal. Take as an example this recording:

This was made from my laptop. Can you hear all that noise? It's caused by electrical interference from components inside the laptop itself. As you can tell, even the physical layout of the components in the PC can impact the quality of the audio signal. When you consider room acoustics such as reverberation and background noise you may find that the signal that is going into the microphone may not be that good to start out with. Couple that with potential electrical interferences from other sources and chances for a high-quality signal arriving at the application can be bleak.

The solution? You could invest in a recording booth, high-end studio microphone, and some high-quality shielded cables. Or, you could use Windows Vista's new Microphone Array technology. The former can cost many thousands of dollars. The latter comes free with Windows Vista and when coupled with a
