美國Listen, Inc
美國Listen公司于1995年由前丹麥B&K著名電聲工程師Steve Temme創(chuàng)立，他創(chuàng)立了世界上第一套應(yīng)用最為廣泛的軟件以及基于聲卡的音頻分析儀。
Soundcheck是一套模塊化基于PC的電聲測試系統(tǒng),它能高性能地完成電聲產(chǎn)品各種參數(shù)的測試。無論對于生產(chǎn)線質(zhì)量控制(QC)簡易操作的要求,還是對研發(fā)（R&D）應(yīng)具備各種擴(kuò)展功能的要求,Soundcheck都能很好的滿足并適用于整個設(shè)計和生產(chǎn)過程。通過在標(biāo)準(zhǔn)的PC上使用專業(yè)的聲卡,Soundcheck確實是作為傳統(tǒng)電聲檢測設(shè)備硬件更好更新的替換品。

Listen, Inc. was founded in 1995 by a group of former Brüel & Kj?r engineers and project managers who recognized that manufacturers of electroacoustic products were frustrated with being forced to use different and typically incompatible measurement systems for production testing and R&D. By not having a common test and measurement platform, Production and R&D groups had great difficulty comparing measurement results. From this, Listen's SoundWare? product development philosophy was born - create application-specific software modules that satisfy particular measurement requirements.

Instead of relying on proprietary hardware for data acquisition and generating test signals, Listen incorporates high-quality sound cards used in professional audio applications. Their large dynamic range, high sampling rates, 24-bit A/D and D/A converters, and low per-channel cost provide a front-end that easily competes with dedicated audio test and measurement instrumentation. Listen's software products are developed using National Instruments LabVIEW? and specialized algorithms. By utilizing this approach, National Instruments chose Listen's premier SoundWare product, SoundCheck?,
as the Best Application of The Year in 1998.

From the company's beginnings in the military communication headset market, today's major manufacturers in loudspeakers, hearing aids, and wireless communication now use Listen's SoundWare products thus enabling our customers to transform sound into knowledge.
