Abstract

Apparatus comprising at least one processor and at least one memory including computer code, the at least one memory and the computer code configured to with the at least one processor cause the apparatus to at least perform: generating a message comprising a first part for determining a sensory space associated with the apparatus; determining a capture control parameter dependent on a sensory space apparatus distribution; and capturing a signal based on the capture control parameter.

Claims

1. Apparatus comprising at least one processor and at least one memory including computer code, the at least one memory and the computer code configured to with the at least one processor cause the apparatus to at least:

generate a message comprising a first part for determining a sensory space associated with the apparatus, wherein the message first part comprises at least one of;

a captured audio signal;

an estimated location of the apparatus; and

an estimated direction of the apparatus;

determine a capture control parameter dependent on a sensory space apparatus distribution; and

capture a signal based on the capture control parameter.

3. The apparatus as claimed in claim 1, wherein the capture control parameter comprises at least one of:

a capture time period;

a capture frequency range; and

a capture direction.

4. The apparatus as claimed in claim 1, further caused to determine the sensory space apparatus distribution by determining whether at least one further apparatus is associated with the sensory space associated with the apparatus.

6. The apparatus as claimed in claim 4, further caused to receive a further message comprising a first part for determining a sensory space associated with the at least one further apparatus.

7. The apparatus as claimed in claim 1, further caused to:

output the signal based on the capture control parameter; and

output the message comprising the first part for determining a sensory space associated with the apparatus to a further apparatus.

9. The apparatus as claimed in claim 1, further caused to receive the sensory space apparatus distribution from a further apparatus in response to outputting the message comprising the first part for determining a sensory space associated with the apparatus to a further apparatus.

11. An apparatus comprising at least one processor and at least one memory including computer code, the at least one memory and the computer code configured to with the at least one processor cause the apparatus to at least:

determine, for at least one sensory space, a sensory space apparatus distribution information by determining whether there is at least one apparatus configurable to capture at least one event in the at least one sensory space; and

generate information on the at least one sensory space apparatus distribution for controlling the capture apparatus in the sensory space.

13. The apparatus as claimed in claim 11, further caused to output the information for controlling the capture apparatus in the sensory space to at least one capture apparatus in the sensory space.

14. The apparatus as claimed in claim 11, wherein the information for controlling the capture apparatus is at least one of:

time division multiplexing information;

spatial division multiplexing information; and

frequency division multiplexing information.

15. The apparatus as claimed in claim 11, further caused to:

combine at least two capture signal clips to produce a combined capture signal by filtering each capture signal clip and combining each filtered capture signal clip; and

receive at least one capture clip from a further apparatus.

18. The apparatus as claimed in claim 11, wherein the information for controlling the capture apparatus in the sensory space comprises a capture handover request.

19. The apparatus as claimed in claim 11, wherein the apparatus caused to determine, for at least one sensory space, a sensory space apparatus distribution information further causes the apparatus to:

determine whether at least one further apparatus is associated with the at least one sensory space.

20. The apparatus as claimed in claim 19, wherein the apparatus caused to determine whether at least one further apparatus is associated with the at least one sensory space further causes the apparatus to:

receive at least one further apparatus message comprising a first part for determining a sensory space associated with the apparatus; and

determine whether at least one further apparatus is associated with the at least one sensory space based on the at least one further apparatus message.
