Abstract
A device and method for providing spatialized audio with dynamic head tracking that includes, in a static phase, providing a spatialized acoustic signal to a user that is perceived as originating from a virtual soundstage at a first location, and, upon determining one or more predetermined conditions are satisfied, which can include whether the users head has exceeded an angular bound, rotating the virtual soundstage to track the movement of the user's head.
Claims20
A pair of headphones, comprising:
- a sensor outputting a sensor signal representative of an orientation of a user's head;
- and
- a controller, receiving the sensor signal, the controller programmed to output a spatialized audio signal, based on the sensor signal, to a pair of electroacoustic transducers for transduction into a spatialized acoustic signal,
- wherein the spatialized acoustic signal is perceived by the user as originating from a virtual soundstage comprising at least one virtual source, each virtual source of the virtual soundstage being perceived as located at a respective position distinct from the location of the electroacoustic transducers and being referenced to an audio frame of the virtual soundstage, the audio frame being disposed a first location aligned with a reference axis of the user's head;
- wherein the controller is further programmed to determine, from the sensor signal, whether a characteristic of the user's head satisfies at least one predetermined condition, the at least one predetermined condition including whether the orientation of the user's head is outside a predetermined angular bound,
- wherein, upon determining the characteristic of the user's head does not satisfy the at least one predetermined condition, the controller is programmed to maintain the audio frame at the first location,
- wherein, upon determining the orientation of the user's head is outside the predetermined angular bound, the controller is programmed to rotate the location of the audio frame about an axis of rotation to reduce an angular offset with the reference axis of the user's head.
