SOUND SIGNAL PROCESS SYSTEM FOR MEASURING POSITION OF SOUND SOURCE

摘要

A voice signal processing system for measuring the location of a sound source is provided to reduce the operational load by converting two or more analog sound source signals into digital signals having plural bits and then sampling the converted signals. An analog processor(20) converts two or more analog sound source signals into digital signals having plural bits. A controller(30) produces a delay time from the digital signals. The controller is a low-performance 8-bit processor. The analog processor comprises an amplifier(210) for amplifying two or more analog sound source signals and a comparator(220) for converting the amplified signals into the digital signals having plural bits.
