Sound signal tone characterization system adds spectral range to parameters |
摘要 |
A sound signal s(t) tone characterization system uses a time varying harmonic spectral range descriptor calculated by Fast Fourier Transform over a sliding time window and a spectral deviation from the centroid with distance between two signals measured as centroid and logarithmic attack time (to, t1).
