This article first introduced the karaoke system based on So C core hardware sound processor

including the four characteristics of the four types of audio processors

the architecture analysis of the sound processor and the optimization of the signal flow based on the original architecture.Secondly

from the fi xed sound delay

change the sound delay on both aspects of the karaoke sound processing system hardware acceleration

a set of hardware architectures that meet the effects of echo

reverb

trim

chorus

and vibrato.Again

elaborate karaoke Vo D system analysis and design

to achieve full-featured

beautiful interface

easy to operate easy.Finally

breaking the traditional karaoke single singing mode

the scoring system for technical analysis and program research

so that through the scoring system to provide users with a new experience from the point of singing to entertainment.
