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(shù)字麥克風(fēng)陣列(VDAM)系統(tǒng)的數(shù)字麥克風(fēng)陣列技術(shù)提供了最終的靈活性。VDAM系統(tǒng)提供了將幾個(gè)麥克風(fēng)串聯(lián)在一起的能力，顯著地減少了雜亂無(wú)章的電纜連接線。由于模擬信號(hào)到數(shù)字信號(hào)的轉(zhuǎn)換是在集成的麥克風(fēng)艙內(nèi)完成的，所以這種結(jié)構(gòu)消除了其他麥克風(fēng)陣列所必需的昂貴附加設(shè)備(前置放大器、模擬到數(shù)字轉(zhuǎn)換設(shè)備和后處理計(jì)算機(jī))。
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.

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(fēng)陣列一直被認(rèn)為是一種在音頻工程的各種應(yīng)用領(lǐng)域很有前途的技術(shù)，包括空間噪聲源捕獲，捕獲現(xiàn)場(chǎng)事件，高保真環(huán)境立體聲，視頻會(huì)議，和聽力領(lǐng)域的分析。盡管有這樣的承諾，但在實(shí)際應(yīng)用中，麥克風(fēng)陣列的使用極其困難。建立一個(gè)陣列，需要用到麥克風(fēng)、前置放大器、模數(shù)轉(zhuǎn)換器、數(shù)據(jù)采集系統(tǒng)以及電纜等所有組件，這是一個(gè)既昂貴又麻煩笨重的設(shè)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(shù)字陣列麥克風(fēng)™ （VDAM）解決了所有這些問題，并在集成模塊中為用戶提供高質(zhì)量的24位數(shù)字化。VDAM的特點(diǎn)是一個(gè)正在申請(qǐng)的互連架構(gòu)，允許多個(gè)麥克風(fēng)通過一個(gè)緊湊的數(shù)字總線以串行鏈的形式連接到一個(gè)小型控制器單元。該設(shè)備支持多達(dá)四個(gè)VDAM鏈，并通過一根工業(yè)標(biāo)準(zhǔn)USB2.0電纜連接到PC。VDAM軟件提供了將錄音文件傳輸?shù)酱疟P的能力。增益和采樣率（高達(dá)48 kHz）可數(shù)字設(shè)置。提供的驅(qū)動(dòng)程序支持標(biāo)準(zhǔn)應(yīng)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.
