Artefacts due to MPEG layer III (MP3) coding are analyzed: non uniform quantization noise, hybrid filter bank aliasing, MDCT pre- and post-echoes. Both objective and subjective evaluation of several MP3 decoded audio files are presented. Finally, it is shown how to predict the subjective perceived quality based on objective measures.

Abstract
Artefacts due to MPEG layer III (MP3) coding are analyzed: non uniform quantization noise, hybrid filter bank aliasing, MDCT pre- and post-echoes. Both objective and subjective evaluation of several MP3 decoded audio files are presented. Finally, it is shown how to predict the subjective perceived quality based on objective measures.
