  • Method and apparatus for processing data representing a time history
    Patent number: 6448484
    Abstract: A method and apparatus for processing data representing a time history of a sonic waveform. A portion of the data is processed to determine a beat frequency by performing a transformation from the time domain to the frequency domain and, based on the energy of the frequencies of the sonic waveform, produce an energy vector for each frequency band. The data is also processed to detect and order transients found in the sonic waveform and use these transients to establish the tempo of the sonic waveform.
