文章针对真实条件下声音的回音和空间感,解释了产生的原因和各种环境条件对其构成的影响,阐述了数字化音频处理中生成声音混响效果的原理。在介绍混响基本原理的基础上,比较深入地分析其特点,并采用参数化各影响混响的条件,分别对高中低各频段处理之后再次合成,同时给出了具体的实现方案。通过对混响效果的解释,总结出声音信号特效处理的一般规律。数字化音频处理无疑,是未来音频处理的主要发展方向。
In this paper, the echoes and spatial perception of sound under real conditions are explained, and the causes of formation and the influence of various environmental conditions on its composition are explained. The principle of generating sound reverberation in digital audio processing is expounded. Based on the introduction of the basic principles of reverberation, the characteristics of the reverberation are analyzed in depth and the conditions affecting the reverberation are parameterized. The high, medium and low frequency bands are processed again and then synthesized again. At the same time, the specific implementation scheme is given. Through the interpretation of the reverberation effect, summed up the general rule of sound signal processing. Digital audio processing is undoubtedly the main direction of future audio processing.
