Paper Abstract:
|
The field of audio compression has been of huge significance over the last decade, especially with the proliferation of the popular MP3 file format for storing music, and distributing audio over data networks, in particular, the Internet. This paper proposes new methods of compression based on the frequently fundamental compositional element of repetition within music. By exploiting the musical content of a piece of audio, data can be discarded that is perceptually redundant, without the removal of frequency components and variable rate encoding found in other compression techniques, such as MP3. Frameworks for a new method of compression are presented and several techniques considered, as possible solutions to the problem of implementing an effective process of data reduction |
