creating auditorial sense

I have started implementation; I have almost completed "auditorial sense" and can "hear" the sound surrundings of the PC. Memory function in a brain.. i have consiered "HOW?" for relatively many days; I DO NOT want to create "Apparent memory" likewise "here is memory..!":

聴覚にあたる部分のプログラミングを行い,ほぼ,完成.これで,PCの周囲の音を聞くことができるようになった.結構長い間「記憶」をどのように実装するかを考えた.いかにも「これが記憶でござい」みたいな実装は避けたいところ.
