Problems solved by technology

Common problems can be found with undesired shading, positioning errors, and failure to form a good externalization, but such findings often do not lead to reliable renderings, as there are still significant individual differences and there is currently no well-established selection method

Embodiment Construction

[0043] In the present invention, a system and method for generating a head-related transfer function is presented. The invention also includes computer program applications and kits that can obtain target user information based on at least the exact shape of the user's head, outer ears, upper torso (known to affect HRTF), and other data that may affect the transfer function. Measurement setup of the head-related transfer function. In addition, the present invention also proposes audio hardware capable of implementing head-related transfer functions without user calibration.

[0044] The head-related transfer function (HRTF) is a separate filter for each ear with different values ​​for each direction of arrival in the horizontal plane (azimuth) and vertical plane (elevation), combining all spectral and temporal domains Effect. HRTF describes all the changes in sound produced from a sound approaching the ear from a given direction. To fully understand the directional effect o...
