Wannamaker, R.A., and E.R. Vrscay, "Fractal Wavelet Compression of Audio Signals,"
J. Audio Eng. Soc., vol. 45, 1997 Jul./Aug.
ABSTRACT
A novel approach to audio signal compression is described which
marries wavelet transform coding with fractal-based compression
techniques. The signal is divided into frames which are subjected to
a Fast Wavelet Transform, with subsequent fractal coding of high
frequency wavelet coefficients using a collage approach. Results
from initial implementations are examined. Compression ratios above
6:1 should ultimately be attainable with good fidelity signal
reconstruction.
