A machine-implemented method for computerized digital signal processing including obtaining a digital signal from data storage or from conversion of an analog signal, and determining, from the digital signal, one or more measuring matrices. Each measuring matrix has a plurality of cells, and each cell has an amplitude corresponding to the signal energy in a frequency bin for a time slice. Cells in each measuring matrix having maximum amplitudes along a time slice and/or frequency bin are identified as maximum cells. Maxima that coincide in time and frequency are identified and a correlated maxima matrix, called a "Precision Measuring Matrix" is constructed showing the coinciding maxima and the adjacent marked maxima are linked into partial chains. |
