美国Listen公司于1995年由前丹麦B&K著名电声工程师Steve Temme创立，他创立了世界上第一套应用最为广泛的软件以及基于声卡的音频分析仪。
Soundcheck是一套模块化基于PC的电声测试系统,它能高性能地完成电声产品各种参数的测试。无论对于生产线质量控制(QC)简易操作的要求,还是对研发（R&D）应具备各种扩展功能的要求,Soundcheck都能很好的满足并适用于整个设计和生产过程。通过在标准的PC上使用专业的声卡,Soundcheck确实是作为传统电声检测设备硬件更好更新的替换品。

Listen, Inc. was founded in 1995 by a group of former Brüel & Kjær 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.
