【摘要】 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。更多还原

【Abstract】 Reverberation is an important characteristic 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 discusses the hardware interface and software. The experiments show that this method can achieve realtime reverberation well under the premise of that the signal is distortionless.更多还原
