... They explored these characteristics further by introducing spectral modifications to the sound pairs (Grey and Gordon 1978). The confirmed acoustic dimensions defining this geometric space, later referred to as the timbral space (Wessel 1979), are: spectral centroid, attack time and spectral irregularity (McAdams and Giordano 2009). The spectral centroid relates to the perceived spectral brightness, the attack time relates to sound onset characteristics, and spectral irregularity relates to the consistency and stability of a spectrum over time. ...
