A "democracy of sound" is typically the goal in live sound, where every member of the audience receives the same high-quality listening experience. One of the most significant challenges in achieving this ideal comes from comb-filtering between coherent low-frequency sound sources and/or early reflections. This tutorial will describe the cutting edge in audio signal decorrelation, namely Diffuse Signal Processing (DiSP), demonstrating how such a decorrelation procedure, if implemented properly, can significantly limit the effects of comb-filtering without perceptually coloring the audio signal. Multiple potential applications will be explored, ranging from large-scale live event subwoofer systems to single subwoofer home theater systems.
