Document Type and Number:
WIPO Patent Application WO/2018/100233
Kind Code:
A3
Abstract:
An apparatus for identifying which sound sources are associated with which microphone audio signals, the apparatus comprising a processor configured to: determine/receive a position/orientation of at least one sound source relative to a microphone array (107); receive at least one microphone audio signal (a1, a2, a3), each microphone audio signal received from a microphone (101,103,105); receive an audio-focussed audio signal (ab,) from the microphone array, wherein the audio-focussed audio signal is directed from the microphone array towards the one of the at least one sound source so as to enhance the audio-focussed audio signal; compare the audio-focussed audio signal against each microphone audio signal to identify a match between one of the at least one microphone audio signal and the audio focussed audio signal; and associate the one of the at least one microphone with the at least one sound source, based on the identified match.
