摘要:
VIrtual bass has drawn wide attention from consumer electronics manufacturers who demand good bass quality from small loundspeakers that have no low-frequency capability. Based on the missing fundamental phenomena, virtual bass aims to extend the low frequency bandwidth psychoacoustically by generating a series of harmonics in the mid-frequency range where loudspeakers can reproduce well. State-of-the-art virtual bass systems usually combine the phase vocoder (PV) approach and the non-linear dev ...More
