摘要

随着多通道音频制作技术的发展,多通道的混响效果处理成为发展的趋势。传统方法操作复杂,且难以达到最佳效果,而人工混响方法目前大多还停留在单声道和双声道实现阶段。设计并实现了一种简单易行的多通道混响方法,通过实验得到房间脉冲响应,由此计算出了一些重要声学参数,最后将房间脉冲响应与一干信号进行卷积,实现混响效果。处理后的干信号,再现了原房间的混响,具有较强的临场感。
        With the development of multi- channel audio production technology,multi- path effect becomes the trend of the development of the processor. Traditional method is complex,and hard to achieve the best effect,and the method of artificial reverberation now still stays mostly in mono and double track implementation phase. A simple and easy method of multi- channel reverberation is designed and realized. Room impulse response is obtained by the experiment,then counting out some important acoustic parameters,and finally the room impulse response is convoluted with a dry signal to produce the reverb effect. After processing the dry signal,it reproduces the original room reverberation,and get the stronger sense of presence.
