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。本文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-channel reverberation processing has become a trend. The traditional methods are complex and difficult to achieve the best results. At present, most of the artificial reverb methods still stay in the mono and two-channel stages. In this paper, we designed and implemented a simple and easy multi-channel reverberation method, obtained the room impulse response experimentally, and calculated some important acoustic parameters. Finally, the room impulse response and a signal were convolved to achieve the reverberation effect . After the treatment of the dry signal, reproduce the reverberation of the original room, with a strong presence.
