Apparatus comprising means for: receiving or accessing, in data form representation, one or more constellations, each constellation defining a spatial arrangement of points forming a shape or pattern; receiving positional data indicative of the spatial positions of a plurality of audio sources in a capture space; identifying, based on the received positional data, a positional correspondence between a subset of the audio sources and at least one of the one or more constellations based on the relative spatial positions of audio sources in the subset and their movement; and responsive to identifying said correspondence, automatically applying at least one mixing action prior to rendering a virtual space version of the audio sources using the video data and/or audio data, the mixing action comprising one or more of: an audio modification action applied to audio signals of one or more audio sources; a visual modification action to change the appearance of one or more captured audio sources; a controlling action applied to perform one or more of modifying the spatial position(s) of one or more captured audio sources, filtering spatial position(s) of one or more captured audio sources, applying a repelling movement to spatial position(s) of one or more captured audio sources, applying an attracting movement to spatial position(s) of one or more captured audio sources, controlling movement of one or more capture devices in the capture space and applying selected audio sources to a first audio channel and other audio sources to one or more other audio channels. receiving or accessing, in data form representation, one or more constellations, each constellation defining a spatial arrangement of points forming a shape or pattern; receiving positional data indicative of the spatial positions of a plurality of audio sources in a capture space; identifying, based on the received positional data, a positional correspondence between a subset of the audio sources and at least one of the one or more constellations based on the relative spatial positions of audio sources in the subset and their movement; and responsive to identifying said correspondence, automatically applying at least one mixing action prior to rendering a virtual space version of the audio sources using the video data and/or audio data, the mixing action comprising one or more of: an audio modification action applied to audio signals of one or more audio sources; a visual modification action to change the appearance of one or more captured audio sources; a controlling action applied to perform one or more of modifying the spatial position(s) of one or more captured audio sources, filtering spatial position(s) of one or more captured audio sources, applying a repelling movement to spatial position(s) of one or more captured audio sources, applying an attracting movement to spatial position(s) of one or more captured audio sources, controlling movement of one or more capture devices in the capture space and applying selected audio sources to a first audio channel and other audio sources to one or more other audio channels. an audio modification action applied to audio signals of one or more audio sources; a visual modification action to change the appearance of one or more captured audio sources; a controlling action applied to perform one or more of modifying the spatial position(s) of one or more captured audio sources, filtering spatial position(s) of one or more captured audio sources, applying a repelling movement to spatial position(s) of one or more captured audio sources, applying an attracting movement to spatial position(s) of one or more captured audio sources, controlling movement of one or more capture devices in the capture space and applying selected audio sources to a first audio channel and other audio sources to one or more other audio channels.
