ABSTRACT:
The invention concerns a method for characterizing the timbre of a time-varying sound signal s(t) using at least one descriptor, where the at least one descriptor includes a harmonic spectral spread of the sound signal s(t). The sound signal s(t) may be compared to other sound signals using the at least one descriptor. The at least one descriptor may also include a harmonic spectral deviation of the sound signal s(t).
