Claim 1:
2. The method of claim 1, wherein the filtering comprises:
sliding, by the computer, the two-dimensional diamond-shaped spectrogram area filter along time and frequency axes of the spectrogram to a first position;
determining, by the computer at the first position of the two-dimensional diamond-shaped spectrogram area filter, whether a central spectral peak magnitude is greater than remaining spectral peak magnitudes; and
in response to the computer determining that the central spectral peak magnitude is greater than the remaining spectral peak magnitudes for the first position of the two-dimensional diamond-shaped spectrogram area filter:
adding, by the computer, the central spectral peak in the subset of the spectral peaks that form the spectral distribution of the audio in the time spread range.
