Abstract: A method of sound-object oriented analysis and of note-object oriented processing a polyphonic digitized sound recording present in the form of a time signal F(A, t) includes the following analytical and processing steps: portion-wise readouts of the time signal F(A, t) using a window function and overlapping windows; Fourier-transforming the readout signal into frequency space, in particular by applying a discrete Fourier transform; calculating an energy value E at each bin from the frequency amplitude resulting from the Fourier transformation, in particular by squaring the real and imaginary parts or forming energy values derived from them; generating a function F(t, f, E); identifying event objects; identifying event objects; identifying note objects; comparing the temporal occurrence of event objects and note objects and associating event objects to note objects in the case of plausible time occurrences; calculating spectral proportion factors for each note object.
