| Abstract: | A reecho system which is implemented by a one-step IIR all-pass filter which is based upon TMS320C5509＇ s DSP has been introduced in this paper.The system could introduce sound which comes from microphone directly or the edited sound-wave file into DSP, then implement the reecho output from the DSP. The system make use of the sound chip AD73311L,has good input＆output characteristic,and could change the characteristic of reecho by change the sampling frequency |
