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: Arrangement for distributing head related transfer function filters. In the arrangement a user device sends a request for a head related transfer function filter to the service being used. The service verifies if the user of the device has a subscription for a head related transfer function filters in the service being used and retrieves a filter as a response to a positive verification result. The service may filter audio channels and transmit filtered audio further. In an alternative embodiment the service transmits the filter to the user device for filtering the audio.

Abstract: An audio system and a method of determining an audio filter based on a position of an audio device of the audio system, are described. The audio system receives an image of the audio device being worn by a user and determines, based on the image and a known geometric relationship between a datum on the audio device and an electroacoustic transducer of the audio device, a relative position between the electroacoustic transducer and an anatomical feature of the user. The audio filter is determined based on the relative position. The audio filter can be applied to an audio input signal to render spatialized sound to the user through the electroacoustic transducer, or the audio filter can be applied to a microphone input signal to capture speech of the user by the electroacoustic transducer. Other aspects are also described and claimed.
