Patent Abstract
The following is a brief description of each of the United States patents that Founder Dr.Olu Lafe and some of his associates were awarded.
| Patent Number | 6567781 |
| Title | Method and apparatus for compressing audio data using a dynamical system having a multi-state dynamical rule set and associated transform basis function |
| Issue Date | 2003-05-20 |
| Inventor | Olurinde E. Lafe |
| Abstract | Digital audio is transformed using a set of filters derived from the evolving states of a dynamical system (e.g., cellular automata). The ensuing transform coefficients are quantized using a psycho-acoustic model that is a function of a fidelity parameter and the distribution of the transform coefficients in critical bands within the transform space. The technique results in compression of the original audio data. Recovery of a close approximation of the original audio data is obtained via a rapid inverse transformation. An encoding method is provided for accelerating the transmission of audio data through communications networks and storing the data on a digital storage media. |
