<p>A method is provided for analysis and noise reduction in a complex waveform using the methods of Fast Find, Harmonic Adjustment and Partial Accentuation. The Fast Find method determines the harmonic content of each tone spectra in the complex waveform. The Harmonic Adjustment method amplifies harmonics in the tone spectra below a crossover frequency. The Partial Accentuation amplifies partials in the complex waveform above the crossover frequency. A Partial Consolidation method consolidates partials by frequency and time into narrow, short term frequency bands for modification by Partial/Resonant Band Accentuation. By combining these methods, noise reduction, audio clarification and other audio enhancements and characterizations are accomplished.</p> |
