Abstract

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 HRTF 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.
