Engine sound synthesizer, motor vehicle and game machine employing the engine sound synthesizer, engine sound synthesizing method, and recording medium containing computer program for engine sound synthesis

Abstract

An engine sound synthesizer includes an engine sound storing section, and a synthetic engine sound data generating section which generates synthetic engine sound data on the basis of engine sound data stored in the engine sound storing section. The engine sound storing section stores therein plural groups of plural entities of engine sound data recorded in different driving states, the plural groups of plural engine sound data entities being stored therein in correspondence with predetermined plural driving state ranges. The synthetic engine sound data generating section generates the synthetic engine sound data by selectively reading out of the engine sound storing section plural engine sound data entities in a group corresponding to one of the driving state ranges specified by externally input driving state specification information and selectively combining the read engine sound data entities. The driving states are each defined, for example, by a throttle opening degree and an engine rotation speed.
