Abstract

Den foreliggende oppfinnelse relaterer seg til et audiokommunikasjonssystem og en fremgangsmåte for forbedret akustisk karakteristikk. Den foreliggende oppfinnelse utnytter Haas-effekten for å simulere et lydbilde som gir en bedre subjektiv følelse av stereolyd sammenlignet med det objektive stereobilde. Det tilveiebringer et system og en fremgangsmåte for å presentere stereobildet på en optimal måte for en assosiert ekkokansellator uten å gå på kompromiss med den subjektive opplevelsen av stereo.
