Abstract:
1. A computer readable medium bearing computer executable instructions for: applying audio data to a peak detection process; detecting the location of at least one prominent peak represented by the audio data in a frequency spectrum and determining the energy of the at least one prominent peak; storing the location of the at least one prominent peak and the energy of the at least one prominent peak into at least one output matrix as output matrix data; applying the output matrix data stored in said at least one output matrix to critical band masking filtering; applying the output matrix data stored in said at least one output matrix to a peak continuation process; and applying the output matrix data stored in said at least one output matrix to an intervals calculation process where a frequency of ratios between peaks are stored into an output vector for the audio data being classified.
