Abstract
An enhanced virtual sound imaging system using triple elevated-speaker projection is proposed. Based on the robustness analysis, an efficient auditory image correction scheme is developed to improve system performance. This is achieved by specially designed inverse filter together with HRTF filtering. The sound imaging algorithm is implemented on a TMS320C6201 EVMDSP board and subjective testing is also carried out to demonstrate the virtual sound effects.
