What is the title of the paper?

Signal decorrelation for sound reinforcement system crossovers

What is the paper about?

The paper focuses on employing diffuse signal processing (DiSP) for minimizing coherent interference in sound reinforcement system crossovers (both spatial and spectral). By using such signal decorrelation, it aims to reduce spatial variance across an audience area, enhancing sound quality and consistency in live event settings.

Why should people be interested in this work?

People involved in live sound reinforcement, such as audio engineers and event organizers, may find this research interesting. It offers a software-based solution to a common problem, potentially improving the auditory experience at live events by ensuring more uniform sound distribution and reducing position-dependent listening experiences. This work could lead to advancements in sound system design and operation.
