Digital signal processing method and system for music fountain

Abstract

The present invention provides a digital signal processing method and system for a music fountain. The method comprises the following steps that: S101, a music file is decoded, and quantized data obtained through decoding are extracted according to a certain sampling frequency; S102, a plurality of times of filtering processing are performed on extracted data information obtained in step S101; S103, the data information processed in the S102 are saved as data information of a fixed encapsulation format, and the data information of the fixed encapsulation format is stored; and S104, when music playing signals are detected, the data information stored in the S103 is read, and frequency converter control signals are generated according to the data information. The digital signal processing method and system for the music fountain provided by the invention have the advantages of simple processing process, convenient use and suitability for high and low-end music fountains of various scales.

Description

technical field [0001] The invention relates to the technical field of musical fountain processing, in particular to a music digital signal processing method and system applied to musical fountains. Background technique [0002] As a kind of artistic waterscape with high ornamental value, musical fountain is welcomed by people in various tourist attractions, large squares, garden landscapes and other occasions. The musical fountain is a combination of waterscape and music appreciation that has emerged in recent years. It is a perfect combination of high technology and nature. The music fountain can integrate waterscape and music, giving people the feeling of shocking and surging with the music, as well as the value of landscape appreciation, music appreciation and infection. [0003] Existing music fountain control devices mainly contain two types: computer digital control music fountain system and analog music fountain control system. With the rapid development of compute...

Problems solved by technology

As the musical fountain becomes larger in scale and more complex in form, and with the rapid development of power electronics technology, modern digital control technology has been able to handle larger and more precise control objects, which is also in line with the development of musical fountains. trend, and the traditional analog control technology has been difficult to continue to adapt to such technical requirements. In addition, the analog control method still has some inherent technical problems in the application of musical fountains, such as control lag and water sound out of sync. Therefore, the use of modern digital signals Processing technology has become an inevitable trend of music fountain control system

[0004] However, the digital signal processing in the existing digital music fountain is mainly based on signal processing technologies such as simple Fourier transform and wavelet transform. The processing process is complicated, the control lags, and the flexibility is not enough. actual needs
