摘要： An audio personalisation method for simulating perception of a vertical displacement of a sound source, the method comprising the steps of: obtaining an input head related transfer function, HRTF, associated with a user; determining an intended vertical displacement for the sound source; selecting at least one frequency region in the input HRTF; and adjusting the amplitude of the selected frequency region(s) to simulate the intended vertical displacement for the sound source. This provides improvements to the generation and/or manipulation of HRTFs to allow adjustment of the perceived location of a sound source.

摘要： A method for obtaining a position of a peripheral device for an audiovisual entertainment system , the method comprising: controlling an audio source to output an audio signal at a first time; determining a second time at which the audio signal arrives at an audio detector, wherein the peripheral device comprises at least one of the audio source and audio detector; and estimating a position of the peripheral device based on an acoustic time-of-flight between the first time and the second time

摘要： A controller for a multimedia entertainment system is provided. The controller comprises a weighted component connected to the controller, wherein the weighted component is rotationally movable relative to the controller. The controller is configured to rotate the weighted component from a start position to an end position to shift the centre of mass of the controller in response to a trigger event; wherein the weighted component stops moving at the end position. This movement of the weighted component provides directional haptic feedback to a user of the controller.

摘要： The invention provides techniques for intelligently positioning speech in a virtual environment. Factors such as user preferences, the location of virtual environment audio and/or visual events, avatar location, and others can be taken into account when selecting a suitable location for the speech. The virtual environment can be a game environment, a meeting environment, an augmented reality environment, a virtual reality environment, and the like. The invention can be implemented by an audio processing unit which may be part of a game console.

摘要： A system for generating a personalised Head-Related Transfer Function, HRTF, for a user, the system comprising: a sound source at a first position; a user device comprising: a left microphone arranged to be at a left ear of the user, when the user device is worn; a right microphone arranged to be at a right ear of the user, when the user device is worn; and a controller configured to: prompt the user to move to series of different second positions; control the sound source to emit a predetermined sound signal when the user is at each second position; obtain a detected sound signal from each of the left and right microphones when the user is at each second position; generate a personalised HRTF based on the predetermined sound signal and the detected sound signal for each microphone and each second position.
