Sound is a wave and so we describe sound. I say in computer ) in terms of sample wave sit. A ] so a describes its max value ie . amplitude . I loudness ) f is the frequency , ie : how fast is the wave repeating . I from 0 to yz goes goes see. A singer described by something like singing a perfect. 2h ( 880 ) t ) basic tone. 5 sin ( 2e ( 1760 )t small terms . If even a moment of sound at loss which of a or b.
