AUDIO CAPTURE WITH MULTIPLE MICROPHONES
First Claim
1. An apparatus comprisingat least one processor;
- andat least one non-transitory memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to;
when the apparatus is configured to transmit a sound source in a voice phone call mode;
output at least one signal from at least one first microphone to the at least one processor as a primary speech signal, andoutput two or more signals from at least two or more second microphones to output a noise reduction signal to the at least one processor; and
/orwhen the apparatus is configured to operate for sound capturing in a multi-media mode;
output at least one signal from the same one or more of the first microphones, and two or more signals from the same at least two or more second microphones to the at least one processor.

Abstract
An apparatus including at least one processor and at least one memory including computer program code configured to: when the apparatus is in a voice phone call mode of sound capture, output a signal from a first microphone as a primary speech signal, and select one or more second microphones to output a noise reduction signal, where the apparatus comprises at least two of the second microphones, and where selection of the one or more second microphones is based at least partially upon a determined use of the apparatus being either a handportable or an integrated handsfree use; and/or when the apparatus is in a multi-media mode of sound capture select one or more of the microphones to output audio signals based upon both a determined type of sound capture feature being used by the apparatus and based upon a determined orientation of the apparatus.
