Professional Digital Audio System Based On TAS3204

Along with economic and technological development,digitization brings convenience to people in many aspects of our lives.In the audio field,the same transformation is in progress.Traditional audio cannot satisfy the demands of people because it just adjusted the volume level,while the heavy structure and complex debugging pattern seem destined to weigh down the professional simulation tuning.The requirements for audio technology are enhanced with the improvement of people's life,professional audio processing is the future trend.The digital audio effect based on DSP(Digit arithmetic processor)discussed and designed in this articl,satisfied all kinds of effects in different conditions.This system applied the method of DSP in signal processing to achieve all kinds of common filtering effects in audio input signals.There were 8 equilibrium points to debug from 20 Hz to 20 KHz.This paper first proposed performance requirements of professional digital audio systems based on DSP.In t.he design of hardware,we choose high cost-performance DSP-TAS3204 produced by TI compared with many main DSP.In the meantime,we introduced the design,the selection of components and implement of a practical system.In software design,we introduced the design,debugging and implement.IIR filtering algorithm was applied in filtering algorithm,and maked simulation by MATLAB.At the last,the system was tested by professional audio test intruments.The system had completed debugging,all functional models were successed in debugging,the performances achieved the desired results,and customers approved the effect.The professional audio system in this article taked tunning requiremens of different audio into account,functional models in this system taked a full consideration of expansibility and applicability to improve follow-up function.
