Abstract: During an initialization of a head pose tracker for a spatial audio system, a spatial audio ambience bed is rotated about a boresight vector to align the boresight vector with a center channel of the ambience bed. The boresight is computed using source device motion data and headset motion data. The ambience bed includes the center channel and one or more other channels. An ambience bed reference frame is aligned with a horizontal plane of a headset reference frame, such that the ambience bed is horizontally level with a user's ears. A first estimated gravity direction is fixed (made constant) in the ambience bed reference frame. During head pose tracking, the ambience bed reference frame is rolled about the boresight vector to align a second estimated gravity direction in the headset reference frame with the first estimated gravity direction fixed in the ambience bed reference frame.

Abstract: A method of enhancing sound heard by a hearing-impaired listener comprises monitoring the sound in an environment in which the listener is located; and manipulating the frequency of high frequency components of the sound in a high frequency band, with little, if any, distortion to components of the sound in a speech frequency band, to enhance spectral cues to aid the listener in sound externalisation and spatialisation.

Abstract: A system for customising the synthesis and generation of spatial hearing in virtual auditory space (VAS) for individual listeners includes a measuring ruler (12) and a digital processing unit (DPU) (14) to which the ruler (12) is connected. The ruler (12) is used for measuring various physical dimensions of the morphology of a person's external auditory periphery (16). The ruler (12) comprises a base (18) insertable into an ear canal (20) of the person's ear. A robotic measuring arm (22) extends from the base (18) and has a measuring tip (24) to enable the ruler (12) to record the Cartesian (x,y,z) coordinates of the tip (24) relative to the base (18). By suitable manipulation of the robotic arm (22), the tip (24) can be positioned at desired locations on the person's external auditory periphery (16) to enable the morphological measurements of the person's external auditory periphery (16) to be effected.

Abstract: A system for recording and reproducing a three dimensional auditory scene for individual listeners includes one or more microphone arrays (2 and 16); a support (3) for holding, moving the microphone array and also for attaching other devices (14); a data storage and encoding device (9); a control interface (13), and a processor and decoding device (10). The microphones in the microphone array (2) preferably have strong directional characteristics. The microphone array support mount (4) can support one or more physical structures (5) to provide directional acoustic filtering. The directional microphone array is electrically connected via a lead (8) to the sound encoding processor (9) and sound decoding processor (10).
