All reactor systems are single threaded by definition, but can exist in a multithreaded environment.

The reactor pattern completely separates application specific code the reactor implementation, which means that application components can be divided into modular, reusable parts.

Experimenal results show that the reverberating algorithms run well on the platform of this system and several natural reverberation effects of halls and rooms can be simulated.

Also, due to the synchronous calling of request handlers, the reactor pattern allows for simple coarse-grain concurrency while not adding the complexity of multiple threads to the system.

In this paper, the formulae are indicated firstly to design artificial reverberator.
