基于音乐特征识别的喷泉控制系统研究

Research on Fountain Control System Based on Music Features Recognition

喷泉是现代园林艺术、工程建筑和景观观赏中的一项重要设施。普通喷泉采用水阀进行调整,喷泉的水柱拥有固定的高度,喷泉的高度无法进行灵活的变化,而音乐喷泉是一种具有极高观赏价值的景观,在实际生活中不仅美化了环境,更为人们带来了欢乐,是近几年一种比较流行的园林建筑与音乐欣赏现结合的产品。介绍一种通过计算机对音乐特征(乐曲旋律、节奏和音频的强弱程度等)的自动识别来控制喷泉系统的工作原理,它使喷泉高度与音乐相关联。不同音乐曲目的特点来通过音乐喷泉的形式进行表达,且通过对音乐特征的识别并对喷泉进行智能控制,使音乐旋律,喷水形式,节奏与情感相结合在一起,水流随着音乐节奏不断变化,加上灯光的渲染,格外迷人。还对音乐信号的本质、音乐信号的识别和信号的转换进行了详细阐述。

Fountain is an important facility in modern garden art,engineering architecture and landscape appreciation.Ordinary fountains are adjusted by water valves,the water column of fountains has a fixed height,and the height of fountains cannot be changed flexibly.Music fountain is a kind of landscape with high ornamental value.In real life,it not only beautifies the environment,but also brings people happiness.It has been becoming apopular product of combining garden architecture and music appreciation in recent years.This paper introduces the working principle of a fountain system controlled by computer automatic recognition of music features(melody,rhythm and audio intensity,etc.)so as to make fountain height related to music.The characteristics of different musical repertoires are expressed in the form of musical fountains.And music melody,water-spraying form,rhythm and emotion are combined by identification of musical features and intelligent control of fountains,the flow of water changes with the rhythm of music,and it becomes particularly attractive the with rendering of lights.This paper also elaborates the essence of music signal,the recognition of music signal and the conversion of music signal in detail.
