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. |
