Digital Processing of Audio to Identify Voices in Fields of View

A device for digital processing audio, comprising:

• a front camera to capture a front field of view;
• a rear camera to capture a rear field of view;
• one or more microphones to capture a sound field;
• and
• one or more processors configured to:
• receive a front video signal from the front camera, a rear video signal from the rear camera, and an audio signal from the one or more microphones;
• digitally process the audio signal to:
• identify voices of persons captured in the front field of view and the rear field of view, and ambient sounds of sound sources outside of the front field of view and the rear field of view;
• and
• generate an audio track to enable an audio renderer to render the voices, and selectively attenuate the ambient sounds, during playback of the front video signal and the rear video signal concurrently;
• and
• store a video container comprising the front video signal, the rear video signal, and the audio track.
