下面是音頻系列的第2部分由Windows景色酣然的隊程序管理員理查Fricks，第一個是理查的片斷 使用話筒列陣提高酣然的捕獲. 這篇第二代產品文章細節如何使更多脫離您的個人計算機通過使用一個數字式話筒。

數字式話筒是完善的適合為窗口景色的話筒列陣技術。 數字式話筒多年來，但近來，能力集成這樣技術每天便攜式計算機以一個付得起的價格沒有。 我是否是否是提及了他們難以置信地緊湊的？ 這底部口岸Akustica數字式話筒的圖片：

Akustica AKU2000

這是高質量，容易地集成膝上計算機個人計算機的有效的數字式話筒的一個了不起的例子。

有擔保提及這個特殊話筒的某些獨特的特徵。 首先， Akustica有給他們合併整個設計硅一塊唯一芯片的一個獨特的製造過程。 這個整體設計在一塊芯片一起安置傳感器、話筒電路、放大器和交換器全部。 這是提供重大好處模式話筒並且其他數字式話筒要求多塊芯片的一個了不起的進步。 明確表達的其中一最容易的好處是它的優越免疫到RF干涉。

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
