A method for selecting perceptually optimal HRTF filters in databases according to morphological parameters

摘要

The present invention relates to a method for selecting a perceptually optimal HRTF in a database according to a morphological parameter. The method uses a first database including HRTF of multiple subjects m, a second database containing morphological parameters of the subject, and a third database corresponding to the perceptual classification of HRTF. According to the present invention, the two most appropriate morphological parameters are sorted by correlating the second and third databases. For example, to obtain an optimized space, a multidimensional space is created to optimize spatial separation between HRTF according to the classification in the third database. An optimized projection model MPO is calculated which is suitable for correlating K optimal parameters with the corresponding position of the HRTF filter in an optimized space. In this manner, any user who does not include that HRTF in the database has the user K and KIt is possible to select at least one HRTF from the database BD1 according to the optimized projection model MPO.
