Abstract :
We propose a VLSI architecture for the 3-D sound generator. The main feature of the proposed 3-D sound architecture is the high performance for sound source localization. We maintain high localization cues owing to the long length of head related transfer function (HRTF). Though short length HRTF can reduce the computation load, the localization cues will degrade. A fast algorithm and an efficient architecture are proposed to generate 3-D sound by the long length HRTF at a 44.1 kHz sampling rate. In addition, the crossfading effect is used for smoothly moving sound source
