Abstract

Apparatus including: a plurality of microphones arranged in a geometry around a first axis such that the apparatus is configured to capture sound from predetermined directions around the formed geometry; a locator configured to receive at least one remote location signal such that the apparatus may locate an audio source associated with a tag generating the remote location signal, the locator including an array of antenna elements, the antenna elements being arranged around the first axis; and a mount configured to mechanically couple the plurality of microphones and the locator.

Claims

1. Apparatus comprising:

a plurality of microphones arranged in a geometry around a first axis such that the apparatus is configured to capture sound from pre-determined directions around the formed geometry;

a locator configured to receive at least one remote location signal such that the apparatus may locate an audio source associated with a tag generating the remote location signal, the locator comprising an array of antenna elements, the antenna elements being arranged around the first axis; and

a mount configured to mechanically couple the plurality of microphones and the locator.

2. The apparatus as claimed in claim 1, wherein the mount is configured to provide an offset perpendicular to the first axis between the plurality of microphones and the locator.

3. The apparatus as claimed in claim 2, wherein the mount is a telescopic mount configured to adjustably change the offset perpendicular to the first axis.

4. The apparatus as claimed in claim 2, wherein the plurality of microphones are arranged in a first ring around the first axis, the locator comprising the antenna elements arranged in a second ring around the first axis, wherein the first ring is one of:

located above the second ring;

located below the second ring; and

located inside the second ring.

5. The apparatus as claimed in claim 1, wherein the plurality of microphones are arranged in a first ring around the first axis, the locator comprising the antenna elements arranged in a second ring around the first axis, wherein the first ring is located outside the second ring.

8. The apparatus as claimed in claim 1, wherein the plurality of microphones is further configured to have a first reference orientation and the locator is further configured to have a second reference orientation, wherein the mount is configured to define an orientation offset between the first reference orientation and the second reference orientation.

9. The apparatus as claimed in claim 8, wherein the mount is configured to align the first reference orientation and the second reference orientation.

10. The apparatus as claimed in claim 1, wherein the locator comprising the array of antenna elements are configured to produce a 360 degree azimuth coverage around the first axis.

11. The apparatus as claimed in claim 1, wherein the plurality of microphones are configured to produce a 360 degree azimuth coverage around the first axis.

12. The apparatus as claimed in claim 1, wherein the tag is associated with at least one remote microphone configured to generate at least one of:

at least one remote audio signal from the audio source, wherein the apparatus is configured to receive the remote audio signal; and

an external audio signal from the audio source, wherein the apparatus is configured to transmit the audio source location to a further apparatus.

26. The apparatus as claimed in claim 1, wherein the apparatus further comprises a plurality of cameras configured to assist the locator to at least one of:

track and locate the audio source.

providing a mount configured to mechanically couple the plurality of microphones and the locator.

15. The method as claimed in claim 14, wherein the mount is configured to provide an offset perpendicular to the first axis between the plurality of microphones and the locator.

16. The method as claimed in claim 15, wherein the mount is a telescopic mount configured to adjustably change the offset perpendicular to the first axis.

17. The method as claimed in claim 15, further comprising arranging the plurality of microphones in a first ring around the first axis, arranging the antenna elements in a second ring around the first axis, wherein the first ring is one of:

located above the second ring;

located below the second ring; and

located inside the second ring.

18. The method as claimed in claim 14, further comprising arranging the plurality of microphones in a first ring around the first axis, arranging the antenna elements in a second ring around the first axis, wherein the first ring is located outside the second ring.

21. The method as claimed in claim 14, wherein the plurality of microphones is further configured to have a first reference orientation and the locator is further configured to have a second reference orientation, wherein the mount is configured to at least one of:

define an orientation offset between the first reference orientation and the second reference orientation; and

align the first reference orientation and the second reference orientation.

23. The method as claimed in claim 14, wherein the locator comprising the array of antenna elements are configured to produce a 360 degree azimuth coverage around the first axis.

24. The method as claimed in claim 14, wherein the tag is associated with at least one remote microphone configured to generate at least one remote audio signal from the audio source, wherein the method comprises at least one of:

receiving the remote audio signal; and

transmitting the audio source location to a further apparatus.

27. The method as claimed in claim 14, wherein the method further comprising a plurality of cameras configured to assist the locator to at least one of:
