A system for dynamically updating a head-related transfer function (HRTF) model that is customized to a user. The system receives one or more images of the user captured by one or more imaging devices. The system determines a pose of the user using the one or more captured images. The pose of the user includes a head-torso orientation of the user. The system updates a HRTF model for the user based on the determined pose including the head-torso orientation. The system generates one or more sound filters using the updated HRTF model and applies the one or more sound filters to audio content to generate spatialized audio content. The system provides the spatialized audio content to the user.
