The VisiSonics Digital Microphone Array (VDAM) system’s patented digital microphone array technology offers the ultimate in flexibility. The VDAM system provides the ability to chain several microphones together in series, significantly reducing wire clutter. Since the A to D conversion is done right at the microphone capsule, the architecture completely eliminates the costly add-ons (preamplifiers, analog to digital equipment, and processing computers) necessary to the operation of other microphone arrays.
VisiSonics数字麦克风阵列(VDAM)系统的专利数字麦克风阵列技术提供了最终的灵活性。VDAM系统提供了将几个麦克风串联在一起的能力，显著地减少了杂乱无章的电缆连接线。由于模拟信号到数字信号的转换是在集成的麦克风舱内完成的，所以这种结构完全消除了其他麦克风阵列所必需的昂贵附加设备(前置放大器、模拟到数字转换设备和后处理计算机)。
Our system easily connects directly to your computer over USB 2.0, and data can be streamed into Matlab, enabling you to tryout your algorithms on the fly. Data can also be recorded for later, more detailed, analysis.
我们的系统可以通过USB 2.0轻松地直接连接到您的计算机，数据可以传输到Matlab，使您可以快捷地检验您的算法。数据也可以被记录下来，供以后进行更详细的分析。

VDAM In-Depth
VisiSonics数字麦克风阵列（VDAM）的终极解决方案
Microphone arrays have long been considered a promising technology for diverse applications in audio engineering, including spatially selective source capture, capturing a live event, ambisonics, video-conferencing, and the analysis of a listening space. Despite this promise, microphone arrays have, in practice, been extremely hard to use. Setting up an array used to require microphones, preamplifiers, digitizers, data acquisition, and cabling between all components — an expensive and cumbersome proposition.
麦克风阵列一直被认为是一种在音频工程的各种应用领域很有前途的技术，包括空间噪声源捕获，捕获现场事件，高保真环境立体声，视频会议，和听力领域的分析。尽管有这样的承诺，但在实际应用中，麦克风阵列的使用极其困难。建立一个阵列，需要用到麦克风、前置放大器、模数转换器、数据采集系统以及电缆等所有组件，这是一个既昂贵又麻烦笨重的设施。
VisiSonics Digital Array Microphones™ (VDAM) address all of these issues and offer users substantial performance with high quality 24-bit digitization in an integrated module. VDAM features a patent-pending interconnection architecture that allows several microphones to be interconnected in a serial chain over a compact digital bus to a small controller unit. This unit supports up to four VDAM chains and connects through a single industry standard USB2.0 cable to a PC. VDAM software provides the ability to stream recordings to disk. The gain and sampling rate (up to 48 kHz) are digitally settable. The provided drivers support standard applications.
VisiSonics数字阵列麦克风™ （VDAM）解决了所有这些问题，并在集成模块中为用户提供高质量的24位数字化。VDAM的特点是一个正在申请专利的互连架构，允许多个麦克风通过一个紧凑的数字总线以串行链的形式连接到一个小型控制器单元。该设备支持多达四个VDAM链，并通过一根工业标准USB2.0电缆连接到PC。VDAM软件提供了将录音文件传输到磁盘的能力。增益和采样率（高达48 kHz）可数字设置。提供的驱动程序支持标准应用程序。
VDAM represents a disruptive new technology, offering users substantial price and performance improvements over commercial alternatives. Advantages include simplified cabling, the elimination of cumbersome and expensive racks of A/D equipment, and the provision of standards based interfacing.
VDAM代表了一种颠覆性的新技术，与传统的商业替代品相比，为用户提供了实质性更低廉的价格和更先进的性能。其优点包括简化布线，消除了繁琐和昂贵的A/D设备机架，并提供了基于标准的接口。
