Abstract
A method and system for reducing head related transfer function (HRTF) storage requirements for 3-D sound processing of an input sound having a specified source angle increment is provided. Interaural time difference (ITD) values are selected based directly on the source angle increment; and HRTFs for processing the input sound are stored in angle increments larger than the source angle increment.
