Abstract
An iterative method for finding which user characteristic data should be used for pruning a database of available HRTFs before selecting an HRTF from the database for a target user (target listener.) The selected HRTF is expected to be the one that is more suitable for target user. This is also referred to as having “personalized” the HRTF selection process for the target user. This is not about computing a suitable HRTF but rather how to use the user characteristic data to improve the chances of selecting the most appropriate one from a database of available HRTFs. Other aspects are also described and claimed.
