Abstract
The present study showed that differences in perceived timbre associated with spectral centroid and spectral irregularity are reflected by fluctuations in the amplitude of the N1 and P2 potentials. Perceived differences in spectral centroid are sufficiently distinctive that generation of auditory images of sounds differing in this property induces changes in the amplitude of the late positive component (LPC), recorded during auditory imagery. This means that the LPC is sensitive to changes in the timbre of the imagined sound. Musicians are more accurate in performing auditory imagery task related to timbre than non-musicians. However, musical expertise does not affect the amplitude of the N1, P2 and LPC potentials.
