基于C54X DSP的实时混响效果器

Real-time reverberation processing system based on C54X DSP

混响是重要的声学特性,在音频应用中极为广泛。文章针对Moorer人工混响算法,设计了基于TMS320VC5402 DSP,STC89C51单片机以及音频芯片TLV320AIC23的实时音频混响器,着重讨论了系统硬件接口以及软件实现。实验结果证明该方法能够很好地在保证声音信号不失真的前提下实现实时混响。

Reverberation is an important charac teristic of sound, which is applied in audio extensively. This paper designs a real-time reverberation processing system based on TMS320VC5402 DSP, STC89C51 MCU and codec chip of TLV320AIC23 in terms of Moorer reverberation algorithm and mainly discmsses the hardware interface and software. The experiments show that this method can achieve real-time reverberation well under the premise of that the signal is distortionless.
