 Abstract
A purpose of developing a sound source tracking system in this paper is to reduce the noise efficiently from the received signal by microphone array and measure the signal`s time delay between the microphones. I have applied the wavelet analysis algorithm to the system and calculated the sound source`s relative position For the performance evaluation, I have compared with the results of utilizing the digital filtering methods based on the FIR LPF using Kaiser window function and the inverse Chebyshev IIR LPF. As a result, I have confirmed the fact that `time-scale` filter using inverse discrete wavelet transform was suitable for this system.
