摘要

Method for estimating computacionalmente time of a seleu00c7u00e7o mu00e9sical system and estimation of time. Method and system of the various achievements of this invention relate to a computational time for a digitally encoded musical selection.In certain achievements of this invention, described below, a short portion of a musical selection is analyzed to determine the time of the musical selection.The sample of the musical selection is transformed computacionalmente digitally encoded to produce a power spectrum corresponding to the sample, again transformed to produce a two-dimensional matrix of power attack (618).The power matrix of attack is then transformed into two-dimensional (806) a set of functions of power attack / period (716) to each of a corresponding set of frequency bands (704 - 707). The functions of energy to attack / period are then analysed to find the range of attack more reliable (808, 8100) is processed in a time calculated returned for analysis (812).
