Abstract: Arrangement for acquiring images for producing a head related transfer function filter is disclosed. In the arrangement the camera of a mobile phone or similar portable device is adjusted for the imaging. All acquired images are analyzed and only suitable images are sent further for producing the head related transfer filter. The arrangement is further configured to provide instructions to the user so that the whole head and other relevant body parts are sufficiently covered.

Abstract: A media system and a method of using the media system to reproduce spatial audio based on head-to-torso orientation, are described. The method includes determining a head-to-source orientation and a head-to-torso orientation based on head orientation data generated by a head tracking device. Determining the head-to-torso orientation includes determining torso movements based on movements of the head. The torso can be determined to move when the head movements meet a head movement condition, such as a predetermined angle of movement or pattern of movement. A binaural audio filter that is based on a head-related transfer function corresponding to both the head-to-source orientation and the head-to-torso orientation is applied to an audio input signal to generate an audio output signal. The audio output signal is played to accurately recreate spatial audio having sounds emitted to the user by a sound source. Other aspects are also described and claimed.

Abstract: Audio processing for a headworn device can include obtaining ear geometry of a user. A frequency response or transfer function can be determined, based on the ear geometry of the user and a model of the headworn device, where the frequency response or transfer function characterizes an effect of a path between a speaker of the headworn device and an ear canal entrance of the user on sound. An equalization filter profile can be generated based on the based on the frequency response or transfer function. The equalization filter profile can be applied to an audio signal, and the audio signal can be used to drive the speaker of the headworn device.
