Abstract: We explore the performance of applying fractal coding on audio data. Some conventional fractal coding problems have been studied with audio data to provide an overview on this subject. A review of fractal coding is presented. We implement a fractal audio coding scheme to carry out the experiments. The performance of the scheme can be controlled by a number of different parameters, including mapping tolerance, scaling factor, partition range, domain specification and bit allocation. Empirical results have been obtained from experimentation on various audio data in our testing set under different parameter combinations.

Keywords: fractal coding; WAVE files; PIFS; partitioned iterated function systems; audio data; mapping tolerance; scaling factor; partition range; domain specification; bit allocation.
