Sažetak
Psychophysical studies show that human listeners are highly sensitive to temporal asymmetry. When an amplitude modulator that is asymmetric in time is applied to a sinusoidal tone, the direction of the asymmetry affects the timbre of the sound. Magnetoencephalography study was carried out to investigate the temporal processing at the level of the auditory cortex by analyzing middle latency auditory evoked fields (MAEF). Spatio-temporal analysis revealed the effects of temporal asymmetry at the level of the primary auditory cortex. The resulting morphology of the source waveforms depended strongly on the temporal features of the envelope of the sounds and less on the specific spectral content of the carrier.
