摘要
对现有的、将双通路立体声信号转换为前方三扬声器重发信号的虚拟声信号处理方法进行了改进,加入了音色均衡的信号处理。同时对该方法进行了主观和客观实验验证,结果表明,经虚拟声信号处理,三扬声器重发不但可得到和普通立体声重发一样的声像效果,而且可提高声像的稳定性,扩大听音区域。
An improvement on current method for converting stereophonic signal to three-front- channel signals by virtual sound signal processing is proposed and a signal processing algorithm with timbre equalization is also introduced. It is proved by subjective and objective experiments that by using virtual signal processing, three-front-channel reproduction is not only able to recreate the same front image as that of stereophonic reproduction, but also able to stabilize image and enlarge listening area.
