三维立体声系统的数字化实现

利用数字信号处理技术，充分发挥多媒体计算机的能力，开发出Advance数字三维立体声系统。通过软件实现了对声音的环绕再生技术（简称SRT）和虚拟听觉空间（简称VAS）的实时处理。它不需要添加任何硬件，即可对WAVE文件、CD音轨、麦克风（MIC）、外接设备（Line）等多种声源进行处理，产生三维音效。文中对空间听觉的原理与Advance系统的软件实现方法进行了详细的论述。

By taking full advantage of the MMX computer and using the Digital Signal Processing technique, the Advance Digital 3D Stereo System is developed. This system implements the real time processing of the Surrounding Regeneration Technology (SRT) and the Virtual Auditory Space (VAS) in software without adding any hardware, it can process various sound sources(such as WAVE files, CD track, Microphone, and external line), and produce 3D sound effect. In this paper the spatial hearing theory and the software implementation of the Advance System are discussed in detail.
