Abstract:
An audio signal processing apparatus, comprising a memory configured to store a set of pairs of predefined left ear and right ear transfer functions, which are predefined for a plurality of reference positions relative to the listener, a processor configured to determine a pair of left ear and right ear transfer functions on the basis of the set of predefined pairs of predefined left ear and right ear transfer functions for the azimuth angle and the elevation angle of the virtual target position and an adjustment filter configured to filter the input audio signal on the basis of the determined pair of left ear and right ear transfer functions and an adjustment function configured to adjust a delay between the left ear transfer function and the right ear transfer function to obtain a left ear output audio signal and a right ear output audio signal.

Claim (Index 3):
The audio signal processing apparatus of  claim 1 , wherein the adjustment filter is further configured to adjust the delay between the left ear transfer function and the right ear transfer function of the determined pair of the left ear and right ear transfer functions as a function of the azimuth angle of the virtual target position by compensating for sound travel time differences associated with a distance between the virtual target position and a left ear of the listener and a distance between the virtual target position and a right ear of the listener.
