Abstract

This paper presents the software implementation of binaural sound source localization employing interaural time difference (ITD) method on NIOS system built on FPGA Altera DE2-70. Hardware components on NIOS system were configured and generated using SOPC builder. FFT based cross correlation algorithm was developed for ITD computation. The developed system was tested in a semi-anechoic room and used white noise as sound source. Best sound arrival estimation obtained for sound coming from 0 to 80 degree in front horizontal plane with average estimation time 0.501 sec
