    Abstract: Embodiments herein relate generally to changing spatial audio fields that are defined for audio sources. In the embodiments, the spatial audio fields are indicated to a user performing audio mixing, for instance by displaying them as polygons on a touch screen. The spatial audio fields move as the related audio sources move, and/or as the position of a notional consumer changes. Apparatus of the embodiments is configured to detect whether at any time (initially, or after movement) there is overlapping of two spatial audio fields. If an overlap is detected, this is indicated to a user performing audio mixing The apparatus then responds to a user input (e.g. a gesture on the touch screen) by detecting the nature of the user input and then moving or sizing one or both of overlapping spatial audio fields and such that overlapping is avoided or reduced.

    Abstract: A method comprising: automatically processing recorded first sensor data from a scene to recognise automatically a first user input from user action in the scene; in response to recognition of the first user input, automatically entering a learning state to enable: automatic processing of the first sensor data from the scene to capture an ad-hoc sequence of spatial events in the scene subsequent to the first user input and automatic processing of subsequently recorded second sensor data from the scene different to the first sensor data of the scene, to recognise automatically a sequence of spatial events in the subsequently recorded second video corresponding to the captured sequence of spatial events.

    Abstract: A method comprising: causing display of a polyhedral virtual object, having a first number (M) of faces, in a virtual visual space, wherein each of at least a second number (N) of the M faces, displays content captured from an associated one of N different camera perspectives; causing rotation of the polyhedral virtual object in the virtual visual space to select a first face of the at least M faces of the polyhedral virtual object by orienting the first face in a predetermined direction within the virtual visual space; and causing display of the content captured from the camera perspective associated with the selected first face of the polyhedral virtual object.

    Abstract: An apparatus for generating at least one distance estimate to at least one sound source within a sound scene comprising the least one sound source, the apparatus configured to: receive at least two audio signals from a microphone array located within the sound scene; receive at least one further audio signal associated with the at least one sound source; determine at least one portion of the at least two audio signals from a microphone array corresponding to the at least one further audio signal associated with the at least one sound source; determine a distance estimate to the at least one sound source based on the at least one portion of the at least two audio signals from a microphone array corresponding to the at least one further audio signal associated with the at least one sound source.

    Abstract: A method including: obtaining at least two audio signals for reproduction, each of the at least two audio signals associated with a respective one of at least two reproduction locations within an audio reproduction space; obtaining within the audio reproduction space at least two zones; obtaining at least one location for a user's position within the audio reproduction space, the at least one location being relative to at least one of the at least two zones and the at least two reproduction locations; and processing the at least two audio signals based on the obtained at least one location for the user's position within the audio reproduction space to generate at least one output audio signal, the at least one output audio signal is reproduced from at least one of the at least two reproduction locations.
