Methods and Systems for Synthesising an HRTF

This abstract first appeared for US patent application 20250099854 titled 'Methods and Systems for Synthesising an HRTF

Original Abstract Submitted

a computer-implemented method of synthesising an hrtf is disclosed. the method comprising: providing the hrtf of a subject measured at a particular measurement angle; processing the hrtf to remove localisation perception features of the hrtf, where the processing comprises: removing spectral notches from the measured hrtf, the resulting processed hrtf referred to as the hrtf′; and calculating a subject's hrtf timbre by subtracting a baseline hrtf at the measurement angle from the subject's hrtf, the baseline hrtf comprising a generalised response component such that the hr tf timbre comprises subject-specific variations in the hrtf. the method further comprises using the hrtf timbre to synthesise an hrtf. the method allows for generating a personalised timbre component of an hrtf to provide better personalisation of an hrtf, thereby providing improved binaural audio.
