Real-Time Correction of the Frequency Response of a Public Address System

Abstract
Correcting the public address (PA) system during a concert event is one of the crucial tasks in ensuring acoustic comfort. However, the existing approaches to such correction do not allow for real-time adaptation to changes in the acoustic properties of the venue that occur during the event. To address this limitation, this article proposes the use of a multiband compressor. It is shown that a zero-latency VST plugin can serve as a multiband compressor. Pink noise can be used as a test signal for system calibration. The results of testing the proposed algorithm, conducted through model and real-world experiments, demonstrate the feasibility and effectiveness of the proposed approach.
