The invention relates to a driving sound library, an apparatus for generating the driving sound library and a vehicle comprising the driving sound library. The driving sound library provides driving sounds classified in various themes to a user by analyzing frequency characteristics and temporal characteristics of sound sources classified into categories and determining a chord corresponding to each sound source based on the frequency characteristics and the time characteristics. Modulated sound sources in which each sound source is modulated are generated by applying a chord corresponding to each sound source. The driving sound sources are generated using the sound sources and the modulated sound sources as input data. Pitches of the driving sound sources are then changed based on the driving sound sources and engine sound orders corresponding to an engine RPM of a preset range. Scores for each theme for the driving sounds are generated.
本发明涉及行驶声音库、用于生成行驶声音库的装置以及包括行驶声音库的车辆。行驶声音库通过分析被分类为类别的声源的频率特性和时间特性并基于频率特性和时间特性来确定与每个声源相对应的和弦,向用户提供被分类为各种主题的行驶声音。生成通过应用与每个声源相对应的和弦对每个声源进行调制的调制声源。利用声源和调制声源作为输入数据来生成行驶声源。然后,基于行驶声源和与预定范围的发动机RPM相对应的发动机声音级数来改变行驶声源的音高。生成行驶声音的每个主题的分数。
