Patent ID: 7215776

Claim:
A method of compressing an audio file comprising: choosing a chaotic system; applying selected digital initialization codes to the chaotic system such that each initialization code produces a periodic orbit and stabilizes the otherwise unstable orbit; generating a basic waveform for each periodic orbit such that the basic waveform is in a one-to-one correspondence to the initialization code for the periodic orbit; selecting and analyzing a section of audio file to be compressed; selecting the basic waveforms to be used and storing their corresponding initialization codes; transforming the section of audio file and the selected basic waveforms to a proper frequency range and storing frequency information describing the transformation; calculating weighting factors to create a weighted sum of the selected basic waveforms to approximate the section of audio file and storing the weighting factors; and combining the stored initialization codes, the stored frequency information and the stored weighting factors to comprise a compressed audio file.
