摘　　要：针对构造家庭影院音响系统的种种弊端,提出一种基于虚拟环绕声(Virtual Surround Sound,VSS)技术的设计方案。以PIC单片机为主控制器,利用QSound实验室的虚拟环绕处理技术,通过可编程调节器实现对音源、音量等的数字化调节。该方案可在无需改造的情况下实现理想的家庭影院音响效果,不但有效克服了传统方案投资大、调试麻烦等缺点,并且系统构成简洁、操作方便。This paper presents an new design method based on Virtual Surround Sound（VSS）technology,aiming at various drawbacks during creation of home theater audio system.In this program,PIC is chosen as the main controller,VSS technology of QSound laboratory and programmable regulator are used to realize the digital adjustment of voice source and voice volume.It realizes of the ideal effect of family theater without any transformation,not only effectively overcoming the shortcomings of huge investment and difficult debugging of traditional methods,but also making the system simple and easy to operate.
