Abstract: Disclosed is a method for determining an audio filter. The method includes obtaining head-tracking data representing a head pose, also referred to as a head position, relative to a torso pose of an intended subject, and selecting a representation of a Head Related Transfer Function, HRTF, from a HRTF database, based on the head-tracking data and information representative of the position and/or direction of a sound source. The method also includes determining the audio filter based on the selected HRTF representation.

Abstract: Disclosed is a method for creating a filter database using head-tracking data. The method includes measuring, for a given sound source, and constructing Head Related Transfer Functions, HRTFs, each HRTF associated with a head pose, also referred to as a position of the head of an intended subject, relative to a torso pose in addition to a position and/or direction of the sound source. The method further includes tracking the head pose relative the torso pose for each measurement to obtain associated head-tracking data, and storing representations of the HRTFs together with the associated head-tracking data and information of the position and/or direction of the sound source in the database.
