Abstract

Abstract: Aimed at the problem which generated by fire sound simulation in virtual reality field, a new fire sound synthesis method was proposed. Most of the sound synthesis methods currently separate the fire sound into low and high frequencies for synthesizing. The influence of low frequency fire sound models was considered and the low frequency signal was synthesized based on the physical visual fire model data. The high frequency sound signal was synthesized based on high frequency blend clips matching method. According to the characteristics of the fire's high frequency, the different frequency bands of high noise signal were generated and separated into the same size windows. The sub-signals with the low frequency signal were matched with the same window size. Various examples and comparisons are presented to verify the plausible method.

Key words: fire, sound, low frequency, high frequency, blend clips
