Since removal of perceptual irrelevance through quantization contributes the largest part of compression for a lossy audio coder, significant distortion or impairment is inherent in the reconstructed audio signal that the decoder outputs. The whole promise of perceptual audio coding is based on the assumption that quantization noise can be hidden behind or masked by the prominent signal components in such a way that it is inaudible.
