Abstract

The invention relates to a music rhythm extracting system based on an MCU hardware platform and a method thereof. The system of the invention comprises a program-controlled gain module, a communication module, a buffer amplification module, an analog-to-digital conversion module and an MCU control module, wherein the buffer amplification module, the analog-to-digital conversion module and the MCU control module are sequentially connected; and the program-controlled gain module and the communication module are respectively connected with the MCU control module. Audio signals of sound systems such as CD drivers, radios and the like are acquired by algorithms such as signal frequency measurement, rhythm extraction, program-controlled gain and the like, thereby extracting rhythm signals of music and outputting energy of music. Meanwhile, the system is provided with interfaces for being communicated with external equipment, thereby being convenient for controlling the external equipment. The invention can be applied to micro music systems such as music toys, household music fountains and the like. The invention has the advantages of small system volume, high portability, low cost, simple interfaces, convenient control, and the like.

Description

technical field [0001] The invention relates to the field of intelligent music emotion analysis, in particular to a music rhythm extraction system based on an MCU hardware platform and a method thereof. Background technique [0002] Music rhythm extraction is widely used in various music systems, ranging from common toys in the market to large music fountains that are currently popular. Music rhythm extraction technology is used. When playing music, the rhythm of the music is extracted to control the peripheral mechanical equipment, so that the action of the entire music system echoes the rhythm of the played music, that is, the behavior and sound are synchronized, giving people visual and auditory enjoyment. [0003] In recent years, as the interactive development of computer technology, communication technology and multimedia technology has become more and more mature, the computer, as a powerful calculation and analysis tool, has continuously penetrated into various field...
