Abstract
The invention relates to a method for determining transfer functions of the HRTF type for an individual, that includes: measuring, for a first number of directions, the transfer functions of the HRTF type specific to the individual; matching the directivity functions associated with the measured functions of the HRTF type, with reference directivity functions associated with reference transfer functions of the HRTF type, the reference functions of the HRTF type being determined for a second number of directions higher that the first number of directions and reconstructing the measured directivity functions from the reference directivity functions.
