This paper presents a hybrid reverberation processor, i.e. a realtime audio signal processing unit that combines a convolution reverb for recreating the early reflections of a measured impulse response (IR) with a feedback delay network (FDN) for synthesizing the reverberation tail. The FDN is automatically adjusted so as to match the energy decay profile of the measured IR. Particular attentio...

In this paper we present a reverberation system based on a multiloudspeaker configuration. The aim of this work is to produce a natural sounding reverberation system with a similar pattern to the produced in real rooms. A new method for sound spatialization is presented, and it is used to locate on the virtual room’s surfaces the early reflections produced in a reverberant space. Each loudspeak...

Supermassive black holes reside at the centers of most, if not all, massive galaxies: the difference between active and quiescent galaxies is due to differences in accretion rate relative to the Eddington rate and thus radiative efficiency. In this contribution, methods for measuring the masses of supermassive black holes are discussed, with emphasis on reverberation mapping which is most gener...

Proper room acoustics play an integral role in the effectiveness of a given chamber for aural communication. This investigation explored the effectiveness of the Electro-Acoustical Simulator for Engineers (EASE), a computer simulation, in determining critical properties of room acoustics by comparing data compiled with the computer model to measured physical data in a detailed case study. The s...
