Abstract: The embodiments relate to a method, including writing a first and a second media entity in a container file; creating a media presentation description (MPD) with a first and a second Representation; the Representations belonging to Adaptation Sets; the Representations being associated with the media entities of the container file; when one of the Representations belongs to a media entity which is a thumbnail to a viewpoint or a thumbnail to an overlay, the method includes writing in the MPD file an association/correspondence/grouping information of the said one Representation with another Representation belonging to a media entity which is a viewpoint or an overlay, correspondingly. The embodiments also relate to a method for parsing, and technical equipment for implementing the methods.

Abstract: A spatial audio signal is received that is associated with a microphone array configured to provide spatial audio capture and additional audio signal(s) associated with an additional microphone, the additional audio signal having been delayed by a variable delay determined such that common components of the spatial audio signal and the additional audio signal(s) are time aligned. A relative position is received between a first position associated with the microphone array and a second position associated with the additional microphone Source parameter(s) are received classifying an audio source associated with the common components and/or space parameter(s) identifying an environment within which the audio source is located Processing effect ruleset is determined based on the source parameter(s) and/or the space parameter(s). Multiple output audio channel signals are generated by mixing and applying processing effect(s) to the spatial audio signal and the additional audio signal(s) based on the processing effect ruleset(s).

Abstract: Described herein are an apparatus, a computer program product, and a method for switching between rendering modes based on location data. The method can comprise based on location data indicative of a location of a user in an environment, causing rendering of audio content, via headphones worn by the user, to be switched from a first rendering mode, in which the audio content is rendered such that at least a component of the audio appears to originate from a first location that is fixed relative to the user, to a second rendering mode, in which the audio content is rendered such that at least the component of the audio content appears to originate from a second location that is fixed relative to the environment of the user. The method can further comprise causing rendering of additional audio content for the user via the headphones.

Abstract: Apparatus including a processor configured to: receive a spatial audio signal associated with a microphone array configured to provide spatial audio capture and at least one additional audio signal associated with an additional microphone, the at least one additional microphone signal having been delayed by a variable delay determined such that the audio signals are time aligned; receive a relative position between a first position associated with the microphone array and a second position associated with the additional microphone; generate at least two output audio channel signals by processing and mixing the spatial audio signal and the at least one additional audio signal based on the relative position between the first position and the second position such that the at least two output audio channel signals present an augmented audio scene.
