Methods and Systems for Synthesising an HRTF

Original Abstract Submitted

a computer-implemented method of training a deep learning model for use in synthesis of a head-related transfer function, hrtf, is disclosed. the method comprises: providing a training dataset comprising a plurality of timbre features, each timbre feature comprising an hrtf measurement of a subject at a particular measurement angle, where the hrtf measurement has been processed to remove localisation perception features of the hrtf; training an autoencoder model, that is conditioned using the measurement angle, to encode the input timbre feature into a latent vector space and reconstruct the input timbre feature from the latent vector space, thereby learning a latent vector space that encodes timbre information independent of the measurement angle, such that the latent vector space is usable to synthesise a timbre component of 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.
