1. An apparatus comprising:
- a binaural microphone system comprising a first transducer and a second transducer which are configured to be located proximate left and right ears of a user and located relative to each other for binaural recording; and
a voice microphone system comprising at least one third transducer configured to sense speaking activity of the user, where the voice microphone system is located on or around a head of the user for sensing the speaking activity; and
where the apparatus is configured, based at least partially upon a voice signal from the at least one third transducer, to remove components corresponding to sound of the speaking activity of the user from signals from the first and second transducers.

Abstract
An apparatus including a microphone array and a removing system. The microphone array includes a binaural microphone system having first and second transducers, and a voice microphone system having at least one third transducer. The removing system is configured to remove, from signals created from the binaural microphone system, components corresponding to sound of a user'"'"'s voice sensed at the at least one third transducer.

12. An apparatus comprising:
-
binaural recording inputs configured to receive left and right channel signals from first and second binaural ear transducers located proximate left and right ears of a user; a voice input configured to receive a voice signal from at least one third transducer located on or around a head of the user; and a system for removing from the left and right channel signals, based at least partially upon the voice signal from the at least one third transducer, components corresponding to sound of a user'"'"'s voice sensed at the at least one third transducer. - View Dependent Claims (13, 14, 15, 16)

21. A method comprising:
-
converting sound sensed at left and right transducers located proximate left and right ears of a user of a binaural microphone into respective first and second electrical signals; converting sound of the user'"'"'s voice sensed at one or more third transducers located on or around a head of the user into a third electrical signal; and removing components from the first and second electrical signals which correspond to the sound of the user'"'"'s voice sensed at the one or more third transducers. - View Dependent Claims (22)

23. A non-transitory program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine, the operations comprising:
-
removing from a first electrical signal, created from a first transducer located proximate a left ear of a user of a binaural microphone system, voice components which correspond to sound sensed at one or more third transducers located on or around a head of the user; and removing from a second electrical signal, created from a second transducer located proximate a right ear of a the user of the binaural microphone system, the voice components which correspond to the sound sensed at the one or more third transducers.
