  • Time–frequency analysis for music signals - Wikipedia

    Time–frequency analysis for music signals is one of the applications of time–frequency analysis.Musical sound can be more complicated than human vocal sound, occupying a wider band of frequency. Music signals are time-varying signals; while the classic Fourier transform is not sufficient to analyze them, time–frequency analysis is an efficient tool for such use.
