AB  - Perceptual audio coding achieves high compression ratio by exploiting the perceptual irrelevance and data redundancies. By the use of advanced and sophisticated signal processing techniques, perceptual coding has generated artifacts sounding very different from the traditional distortions. In audio industry, it is always an important step to maturing a technology by modeling, measuring, and listening the artifacts induced from the technology. In the past, there have been some types of artifacts defined in linear quantization or MP3 music tracks. With the advance of the new coding modules in AAC, SBR, and parametric coding, various new types of artifacts are generated. This paper models the frequently induced audible artifacts and analyzes the problematic encoder modules.
