Abstract
Transform coders artificially divide an source signal into blocks, then process and code each block independently of each other. This leads significant variations between blocks, which may become visible or audible as discontinuities at the block boundaries. Referred to as blocking artifacts or blocking effects, these artifacts may appear as “tiles” in decoded images or videos that were coded at low bit rates. In audio, blocking artifacts sound like periodic “clicking” which is considered as annoying by many people.While the human eye can tolerate a large degree of blocking artifacts, the human ear is extremely intolerant of such periodic “clicking”. Therefore, transform coding is rarely deployed in audio coding.
