Claim Text:
1. A method of processing an original domain signal, comprising: receiving an input signal comprising an original domain signal and creating a first window data set and a second window data set from the signal, wherein an initiation of the second window data set is offset from an initiation of the first window data set; converting the first window data set and the second window data set to a frequency domain and storing the resulting data as data in a second domain different from the original domain; performing complex spectral phase evolution (CSPE) on the second domain data to estimate component frequencies of the first and second window data sets; using the component frequencies estimated in the CSPE, sampling a set of second-domain high resolution windows to select a mathematical representation comprising a second-domain high resolution window that fits at least one of the amplitude, phase, amplitude modulation and frequency modulation of a component of an underlying signal wherein the component comprises at least one oscillator peak; generating an output signal from the mathematical representation of the original signal as at least one of: an audio file; one or more audio signal components; and one or more speech vectors; and outputting the output signal to an external system.
