Abstract: There are disclosed various methods, apparatuses and computer program products for audio encoding and reproduction. In accordance with an embodiment the method for audio encoding comprises generating audio tracks from sound signals from sound object (402-406); defining quality limits for playback of the audio tracks; combining the audio tracks into an audio presentation; and attaching information regarding the quality limits with the audio presentation. In accordance with an embodiment the method for audio decoding comprises receiving an audio presentation comprising audio tracks; receiving information regarding quality limits for playback of the audio tracks; obtaining information about a playback environment; estimating the playback environment to determine an optimal listening area (400) within the playback environment by using information regarding the quality limits.

Abstract: A method, an apparatus and a computer program are provided. The method comprises defining a first mapping that maps a virtual space to a real space; using a tracked real point of view of a user in the real space and the first mapping to determining a virtual point of view of the user within the virtual space defined by the user's virtual location and virtual orientation; causing rendering to the user of at least part of a virtual scene determined by the virtual point of viewof the user within the virtual space, while the virtual space is mapped to the real space using the first mapping; altering, based on a grasp and move gesture performed by the user on a virtual location in the virtual space that differs from the virtual location partially defining the user's virtual point of view, the mapping of the virtual space to the real space from the first mapping to a second mapping; using a tracked real point of view of the user in the real space and the second mapping to determine a virtual point of view of the user within the virtual space defined by the user's virtual location and virtual orientation; and causing rendering to the user of at least part of a virtual scene determined by the virtual point of view of the user within the virtual space, while the virtual space is mapped to the real space using the second mapping.

Abstract: A method comprising: using a tracked real point of view of a user in a real space and a first mapping between the real space and a virtual space to determine a point of view of a virtual user within the virtual space; causing rendering to the user at least part of a virtual scene determined by the point of view of the virtual user within the virtual space; and using a selected one of a plurality of different mappings to map tracked user actions in the real space to actions of the virtual user in the virtual space. wherein, when a first mode is selected, the method comprises mapping tracked user actions in the real space, using the first mapping, to spatially-equivalent actions of the virtual user in the virtual space, and wherein, when a second mode is selected, the method comprises mapping tracked user actions in the real space, using a second mapping different to the first mapping, to non-spatially-equivalent actions of the virtual user in the virtual space, wherein the second mapping makes available user interactions within a zone of the virtual space unavailable using the first mapping.
