Content-based retrieval of audio example on MP3 compression domain

This paper considers content-based retrieval of a MP3-based (MPEG 1 layer III) digital music archive. In our approach, two kinds of value, scale-factor (SCF) and sub-band coefficient (SBC), in a MP3 frame are used. These two values are extracted from the MP3 decoder to compute the MP3 features for indexing the MP3 objects. Evaluations on a content-based MP3 retrieval system indicate that our approach can achieve a good performance.
