Abstract
This paper presents issues relating to information and musical content dealt with as part of the development of an innovative audio compression system, designed to exploit repetition sequences in audio, and particularly, music. The paper briefly introduces and describes how musical content and structure within audio can be exploited to achieve compression. A new system to take advantage of these hypotheses is described. The paper introduces a new file format to deal with high-level data chunks and repetitive structuring. The practicalities of searching for large blocks of audio data are discussed and evidence provided of the high amounts of complexity involved in performing brute-force searches for self-similar matching. This high complexity is the subject of current work by the authors and research to date so far reveals that search time can be reduced by considering content analysis, this time to reduce complexity rather than data volume.
