Abstract: A method including receiving an audio scene including at least one source captured using at least one near field microphone and at least one far field microphone. The method includes determining at least one room-impulse-response associated with the audio scene based on the at least one near field microphone and the at least one far field microphone, accessing a predetermined scene geometry corresponding to the audio scene, and identifying best match to the predetermined scene geometry in a scene geometry database. The method also includes performing RIR comparison based on the at least one RIR and at least one geometric RIR associated with the best matching geometry and rendering a volumetric audio scene based on a result of the RIR comparison.

Abstract: A method including recognizing at least one gesture to define at least one computer-implemented virtual boundary in a monitoring space, wherein the gesture includes a motion along a path and at a location in a monitored scene space wherein there is a correspondence between the monitoring space and the monitored scene space; causing implementation of the at least one virtual boundary in the monitoring space corresponding to the scene space, wherein at least part of the virtual boundary is determined by the path in the monitored scene space and the at least part of the virtual boundary is located in the monitoring space at a corresponding location equivalent to the path location; and processing received data to generate a response event when there is, relative to the at least one virtual boundary, a change in a portion of the monitored scene space.
