摘要： An apparatus including circuitry configured for: displaying content within a viewport; displaying a symbol representing a sound source within the viewport; detecting one or more gestures that place the displayed symbol in the displayed content; disambiguating between a first placement method, performed for the symbol, that locks the sound source to a position that moves with displayed content moving within the viewport and a second placement method performed for the symbol that is different to the first placement method and locks the sound source to a position that does not move with displayed content moving within the viewport, wherein the first placement method includes a disambiguating gesture relative to the viewport, for the symbol, indicating movement of the symbol relative to the viewport that disambiguates the first placement method from the second placement method.

摘要： An audio processing technique including obtaining a multi-channel audio signal, a first sound direction of interest and a second sound direction of interest; determining, for one or more frequency bands, a respective first range of sound directions encompassed by a first focus pattern directed to said first sound direction of interest and a respective second range of sound directions encompassed by a second focus pattern directed to said second sound direction of interest; determining, for said one or more frequency bands, respective overlap between the first and second ranges of sound directions; and deriving, based on the multi-channel audio signal and in accordance with said first and second focus patterns, a processed audio signal where sounds in said first and second sound directions of interest are emphasized in relation to sounds in other sound directions, said derivation including controlling emphasis in dependence of the determined overlap.

摘要： A method is provided for providing various operational states based on user input type. In particular, an example method may include providing for operation in a first operational state, receiving a user input, and determining if the user input is of a first input type. A second operational state based on the user input may be determined in response to the user input being of the first input type. Methods may include providing for operation in the second operational state, different from the first operational state, in response to receiving the user input of the first input type, where the second operational state precludes input of a second input type and allows input of a first input type, where the first and second input types are different from one another.

摘要： A method, apparatus and computer program wherein the method includes: obtaining at least three ambient audio signals wherein at least one of the ambient audio signals is to be processed with a first directional transfer function pair and at least one other of the ambient audio signals is to be processed with a second directional transfer function pair wherein the directional transfer function pairs to be used are based on target directions of the ambient audio signals; determining a change of the target direction for the at least one ambient audio signal to an updated target direction; selecting an updated directional transfer function pair associated with the updated target direction wherein the updated directional transfer function pair is selected from a plurality of directional transfer functions and the updated directional transfer function pair is more closely associated with the updated target direction than the first directional transfer function pair; and processing the at least one ambient audio signal with the selected updated directional transfer function pair and processing the at least one other ambient audio signal with the second directional transfer function pair.
