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數字麥克風陣列(VDAM)系統(tǒng)的專利數字麥克風陣列技術提供了最終的靈活性。VDAM系統(tǒng)提供了將幾個麥克風串聯(lián)在一起的能力，顯著地減少了雜亂無章的電纜連接線。由于模擬信號到數字信號的轉換是在集成的麥克風艙內完成的，所以這種結構完全消除了其他麥克風陣列所必需的昂貴附加設備(前置放大器、模擬到數字轉換設備和后處理計算機)。

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.

我們的系統(tǒng)可以通過USB 2.0輕松地直接連接到您的計算機，數據可以傳輸到Matlab，使您可以快捷地檢驗您的算法。數據也可以被記錄下來，供以后進行更詳細的分析。

VDAM In-Depth

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.

麥克風陣列一直被認為是一種在音頻工程的各種應用領域很有前途的技術，包括空間噪聲源捕獲，捕獲現場事件，高保真環(huán)境立體聲，視頻會議，和聽力領域的分析。盡管有這樣的承諾，但在實際應用中，麥克風陣列的使用極其困難。建立一個陣列，需要用到麥克風、前置放大器、模數轉換器、數據采集系統(tǒng)以及電纜等所有組件，這是一個既昂貴又麻煩笨重的設施。

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數字陣列麥克風™ （VDAM）解決了所有這些問題，并在集成模塊中為用戶提供高質量的24位數字化。VDAM的特點是一個正在申請專利的互連架構，允許多個麥克風通過一個緊湊的數字總線以串行鏈的形式連接到一個小型控制器單元。該設備支持多達四個VDAM鏈，并通過一根工業(yè)標準USB2.0電纜連接到PC。VDAM軟件提供了將錄音文件傳輸到磁盤的能力。增益和采樣率（高達48 kHz）可數字設置。提供的驅動程序支持標準應用程序。

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代表了一種顛覆性的新技術，與傳統(tǒng)的商業(yè)替代品相比，為用戶提供了實質性更低廉的價格和更先進的性能。其優(yōu)點包括簡化布線，消除了繁瑣和昂貴的A/D設備機架，并提供了基于標準的接口。

VisiSonics currently uses the VDAM to produce its innovative RealSpace™ Panoramic Audio/Visual Camera. Contact VisiSonics to find out how you can create microphone arrays to support your test and measurement, or how you can incorporate VDAM in your products.
