Abstract
Although data model and quantization have been discussed in detail in the earlier chapters as the tool for effectively removing perceptual irrelevance, a question still remains as to which part of the source signal is perceptually irrelevant. Feasible answers to this question obviously depend on the underlying application. For audio coding, perceptual irrelevance is ultimately determined by the human ear, so perceptual models need to be built that mimic the human auditory system so as to indicate to an audio coder which parts of the source audio signal are perceptually irrelevant, hence can be removed without audible artifacts.
