In our paper, we discuss direct processing of MP3 audio codes as well as audio artifacts introduced by MP3 compression and tandem coding problem. We also illustrate advantages, disadvantages, problems, and limits of audio processing in MP3 compressed domain with respect to time resolution, hybrid filter bank, alias artifacts, and unmasking effects. Our final section provides a multi-level approach to direct process MP3 codes and possible algorithms to handle MP3 in compressed domain.

Abstract
In our paper, we discuss direct processing of MP3 audio codes as well as audio artifacts introduced by MP3 compression and tandem coding problem. We also illustrate advantages, disadvantages, problems, and limits of audio processing in MP3 compressed domain with respect to time resolution, hybrid filter bank, alias artifacts, and unmasking effects. Our final section provides a multi-level approach to direct process MP3 codes and possible algorithms to handle MP3 in compressed domain.
