US Patent 9693009 Sound source selection for aural interest

A viewer-selectable audio display region is associated with certain pixels of a video feed visible to the viewer of the video. Directional microphones provide audio signals for specific audio sources within a three-dimensional (3-D) video recording space. The recorded video signal is augmented with the audio signals and identified sound sources. The sound sources are mapped to pixels on the display. When the viewer selects the pixels, one or more audio recordings are: (i) played; (ii) amplified; (iii) mixed; and/or (iv) otherwise processed.
