摘　　要：介绍一种高保真的音频信号处理系统,给出了前端音频信号调理电路设计,实现了DSP芯片TMS320VC5410与语音转换芯片TLC320AD50C的硬件接口设计,并通过FIR算法实现了对音频信号的处理。测试结果表明,此音频处理系统达到预期要求。This paper designs a kind of Hi-Fi real-time audio signal processing system. The design gives the signal conditioning circuit, accomplishes the hardware interface design of DSP chip TMS320VC5410 and chip-to-speech TLC320ADSOC, and processes audio signal by FIR arithmetic. It is tested that the audio signal processing effect has reached the expected requirements.
