    Abstract: In respect of first and second virtual-or-augmented reality content each comprising at least respective visual imagery for display in a three-dimensional virtual space; based on real-world space information comprising at least a first and second determined sub-space comprising a different part of a real-world space in which a first user is located, and second-user information indicative of the presence of a second user; provide for display of a three-dimensional hybrid virtual space that is user-explorable, the hybrid virtual space based on a combination of virtual spaces generated from at least the first and the second virtual-or-augmented reality content and respectively presented in positions to correspond to the first and second sub-spaces; and provide for display to the second user, who is not presented with said hybrid virtual space, of an indication of the boundary of one or both of the first and second sub-spaces.

    Abstract: An apparatus comprising means configured to: obtain at least one parameter value (106) associated with at least two time-frequency parts of at least one audio signal (104); obtain at least one similarity value based on the at least one parameter value (106) associated with the at least two time-frequency parts of at least one audio signal (104); determine at least one group of time-frequency parts from the at least two time-frequency parts of at least one audio signal (104), the at least one group of time-frequency parts based on the at least one similarity value; and generate for the at least one group of time-frequency parts at least one associated group parameter (204), the at least one group parameter (204) based on the at least one parameter value (106) associated with the time-frequency parts.

    Abstract: There is inter alia disclosed an apparatus for spatial audio encoding comprising: means for determining at least two of a type of spatial audio parameter for one or more audio signals, wherein a first of the type of spatial audio parameter is associated with a first group of samples in a domain of the one or more audio signals and a second of the type of spatial audio parameter is associated with a second group of samples in the domain of the one or more audio signals; and means for merging the first of the type of spatial audio parameter and the second of the type of spatial audio parameter into a merged spatial audio parameter.

    Abstract: An apparatus comprising means for: capturing an audio scene using multiple microphones; determining that the captured audio scene has unacceptable detected noise; in dependence upon determining that the captured audio scene has unacceptable detected noise, searching both different sets of one or more microphones and different physical rotation angles of the microphones to find a combination of a first set of one or more microphones and a first physical rotation angle of the microphones that captures the audio scene with acceptable detected noise; and controlling the physical rotation angle of the microphones to be the first physical rotation angle of the microphones and capturing the audio scene using the combination of the first set of one or more microphones and the first physical rotation angle of the microphones.
