Abstract

This paper presents three schemes for re-compressing MP3 (MPEG-1 Layer III) audio bitstreams. The first two schemes are lossless ones, which exploit the inter-frame redundancies of the main data (the scale factors and the quantized MDCT coefficients) of the MP3 bitstream. The third scheme is a lossy approach, which exploit the redundancies between consecutive beat-patterns. The aim is to study the potential of the new coding schemes. Preliminary results are demonstrated in this paper.
