Abstract: An exemplary sound extraction system generates an averaged set of audio signals by averaging values derived from different audio signals. For example, the sound extraction system generates an averaged set of audio signals by averaging values derived from a first set of audio signals captured at a particular location with respect to a capture zone, and values derived from a second set of audio signals captured at different locations with respect to the capture zone. Based on the averaged set of audio signals, the sound extraction system generates a location-diffused signal representative of sound in the capture zone. Corresponding systems and methods are also disclosed.

Abstract: An exemplary microphone capture simulation system accesses a captured set of audio signals captured by a plurality of directional microphones disposed at a plurality of locations on a perimeter of a capture zone of a real-world scene. The system identifies a location within the capture zone that corresponds to a virtual location at which a user is virtually located within a virtual reality space that is based on the capture zone. Based on the captured set of audio signals and the identified location, the system generates a simulated set of audio signals representative of a simulation of a full-sphere multi-capsule microphone capture at the identified location. The system processes the simulated set of audio signals to form a renderable set of audio signals configured to be rendered to simulate full-sphere sound for the virtual location while the user is virtually located at the virtual location.

Abstract: An exemplary ambient sound extraction system accesses a location-confined A-format signal that includes a first set of audio signals captured by different capsules of a multi-capsule microphone disposed at a first location with respect to a capture zone of a real-world scene. The ambient sound extraction system also accesses a second set of audio signals captured by a plurality of microphones disposed at a plurality of other locations with respect to the capture zone. The ambient sound extraction system generates a location-diffused A-format signal. The location-diffused A-format signal includes a third set of audio signals that is based on the first and second sets of audio signals. Based on the location-diffused A-format signal, the ambient sound extraction system generates a location-diffused B-format signal representative of ambient sound in the capture zone. Corresponding methods are also disclosed.
