Abstract
An engine sound generating system, positioned in a moving object, includes a repeating section selection unit for recognizing at least one vowel section from an input sound source, and selecting a repeating section to be repeated based on the vowel section; a repetitive waveform generating unit for generating a repetitive waveform based on the selected repeating section; and an engine sound output unit for generating and outputting an engine sound by interpolating the generated repetitive waveform.
Claims19
An engine sound generating system based on a string sound source, positioned in a moving object, the system comprising:
- a repeating section selection unit configured to recognize a vowel section from an input sound source and to select a repeating section to be repeated based on the vowel section;
- a repetitive waveform generating unit configured to generate a repetitive waveform based on the selected repeating section;
- and
- an engine sound output unit configured to generate and output an engine sound by interpolating the repetitive waveform.
An engine sound generating method based on a string sound source of an engine sound generating system which is positioned in a moving object, the engine sound generating unit including a repeating section selection unit, a repetitive waveform generating unit, and an engine sound output unit, the method comprising:
- (a) recognizing, by the repeating section selection unit, a vowel section from an input sound source, and selecting a repeating section to be repeated based on the recognized vowel section;
- (b) generating, by the repetitive waveform generating unit, a repetitive waveform based on the selected repeating section;
- and
- (c) generating and outputting, by the engine sound output unit, an engine sound by interpolating the repetitive waveform.
