METHOD AND APPARATUS FOR SOUNDSTAGE EXTENSION BASED ON THE METHOD HRTF-

原文（中文）

A computing apparatus with the proposed Method HRTF—for soundstage extension, upon which some inherent issues of the conventional Method HRTF such as the need for pre-measuring or simulating, highly individual dependence, small sweet spot, etc., have been effectively resolved. With the approaches that decoupling the individual-dependent segment from the entire HRTF chain, moving the intersection-point forward outside the ear, and simplifying the frequency response with relative-quantity approximations, the goal—“listening with one's own ear” is achieved with robustness improved and sweet spot enlarged. The present invention can be deployed in diverse scenarios: the stereo speakers; a foundational algorithmic module for advanced applications such as home theater systems, etc.; and an audio file in a particular encoding format can be also generated upon the invention that the soundstage can be extended readily through replaying with conventional stereo speakers.
