Abstract(in English) | The basic concept of artificial reverberation based on a convolution algorithm has been proposed since early times. Expensive and large-scale systems have been required to implement that concept, however, because of the huge number of operations to be computed in real time. The recent progress in semiconductor technology has made the concept feasible at a reasonable cost and on a practical scale. This paper describes the usability of the real-time convolution system, not only as a simple reverberator, but also in the field of multi-channel sound field creation, by weighing it against conventional IIR type reverberators. Taking a commercial convolution-type reverberator (Yamaha SREV1) as an example, it introduces an overview of the configuration, application-specific LSI and sound field creation of the reverberator, and also describes its application to multi-channel surround-sound systems. |
