3D环绕立体声技术的数字化

The Digitalization of 3D Surround Stereophonic Technology

ＳＲＳ３Ｄ 环绕立体声技术充分利用“耳廓效应”，只需两只音箱，就能从任何音源（无需杜比编码）中恢复出３Ｄ环绕立体声，故ＳＲＳ环绕声效处理器在市面上倍受欢迎。文中利用数字信号处理技术和心理声学方面研究的最新成果，基于计算机多媒体系统，以ＶｉｓｕａｌＣ＋ ＋ 为工具开发出了一播放器软件。该播放器可对Ｗａｖｅ 和ＣＤ音频实时地进行处理播放，产生ＳＲＳ环绕声效处理器所具有的３Ｄ环绕立体声效果，成功地实现了３Ｄ环绕立体声技术的数字化，从而克服了模拟技术带来的局限性。

The SRS surround effect processors are very popular in market since SRS 3D surround stereophoic technology can retrieve 3D surround effect from any kind of sound source (without Dolby encoding) with only two sound boxes by well using 'pinnae effect'. Based on computer multimedia system a softeware player was developed with Visual C++ by using the digital processing technology and latest research achievements in auditory psychology. The player can achieve the 3D surround stereophonic effect of the SRS surround effect processors on Wave nd CD audio by processing them in real time. The successful digitalizaton of 3D surround stereophonic technology overcomes the limitations brought forward by analogy technology.
