Design and Simulation of Artificial Reverberator Based on Simulink

Abstract

Artificial reverberator is now widely used in broadcasting station, television station, singing and dancing hall, etc. It plays an important role in beautifying music, sugaring singing, glorifying phonetic timbre and the artistic re-creation. It can also produce many kinds of special acoustics. However, artificial reverberator is a very complex system related with many important items especially its time-delay and feedback. And it is hard for designers to find the parameter of these items accurately. Simulink is perfect tool to design the artificial reverberator and set the optimal parameter through simulation, which can result in better acoustics. In this paper, the design of artificial reverberator based on Simulink is introduced in detail. Also, a realistic simulation package is presented on the base of the discussion of the interface between Simulink and GUI. Experimental results show that the acoustics of artificial reverberation are much more natural than before.

A Genetic Algorithm For Parameter Adjustment Of An Artificial Reverberation Model

“…GAs have been successfully used in a wide variety of applications in engineering and science [3], [4]. The use of Genetic Algorithms (GA) for searching the parameters of Infinite Impulse Response (IIR) filters was presented by [5]. Another GA approach, was also proposed by [6] as part of experiments with reverberation algorithms.…”
