Abstract
An apparatus including a body, a plurality of microphones arranged in a predetermined geometry relative to the body such that the apparatus is configured to capture sound substantially from all directions around the body to produce direction and ambience information for the captured sound, and electronics for processing signals from the plurality of microphones.
Claims21
Apparatus comprising
- a body,
- a plurality of microphones arranged in a predetermined geometry on the body such that the apparatus is configured to capture a sound field in a plurality of directions around the body based on the predetermined geometry, wherein the plurality of microphones of the predetermined geometry are configured to enable capture of the sound field from any direction around the body such that substantially at least three microphones of the plurality of microphones receive sound without acoustic shadowing in any direction around the body while at least one other microphone of the plurality of microphones receives said sound with acoustic shadowing relative to a capture direction of said at least three microphones so as to ensure that sounds from the capture direction are captured without acoustic shadowing using the at least three microphones, and
- electronics for processing signals from the plurality of microphones, where the electronics is configured to determine ambience information of the sound field and direction information of at least one sound source within said sound field around the body based, at least partially, upon the plurality of microphones.
A method for capturing sound, comprising:
- capturing a sound field with a plurality of microphones, located in a predetermined geometry on a body of a capture apparatus, from a plurality of directions around the body based on the predetermined geometry, wherein the plurality of microphones of the predetermined geometry are configured to enable capture of the sound field from any direction around the body such that substantially at least three microphones of the plurality of microphones receive sound without acoustic shadowing in any direction around the body while at least one other microphone of the plurality of microphones receives said sound with acoustic shadowing relative to a capture direction of said at least three microphones so as to ensure that sounds from the capture direction are captured without acoustic shadowing using the at least three microphones, and
- processing signals from the plurality of microphones, where the processing of the signals from the plurality of microphones is configured to produce direction information of at least one sound source within said sound field and ambience information of said sound field around the body based, at least partially, upon the plurality of microphones.
